* m4/largefile.m4 (AC_SYS_LARGEFILE_FLAGS): Work around a

@noindent where appropriate.
|

1999-11-07 Paul Eggert
|

* src/grep.c (usage): Fix misspelling.
|

|
||||
1999-11-07 Paul Eggert
|
||||
|
||||
Don't assume that the C library has re_set_syntax and friends.
|
||||
* src/Makefile.am (base_sources): Add regex.c, regex.h.
|
||||
(EXTRA_DIST): Remove regex.c, regex.h.
|
||||
|
||||
* src/grep.c (prtext): Use out_quiet, not not_text, to decide
|
||||
whether to set pending to zero at the end.
|
||||
(not_text): Remove static variable, undoing latest change.
|
||||
(grep): Likewise.
|
||||
|
||||
* doc/grep.texi: Tighten up the text, and fix some minor
|
||||
spelling and usage errors. Use @enumerate rather than @table
|
||||
@samp, since it's better for Q&A format. Add cross
|
||||
references.

1999-11-01 Alain Magloire
|
||||
|
||||
* src/search.c: Use the more portable [[:alnum:]]
|
||||
to define a word instead of Ascii dependent [0-9A-Za-z]
|
||||
* src/grep.c: make not_text global to not display text when
|
||||
the context switches -A/-B/-C are use on binary files.
|
||||
* make grep-2.3g available for testing.
|
||||
* configure.in: drop support for --without-included-regex.
|
||||
This was generating bogus bug reports, since many GNU/Linux
|
||||
users have different version of glibc. And glibc maintainers
|
||||
decided to drop k&r support.
|
||||
|
||||
1999-11-01 Arnold D. Robbins
|
||||
|
||||
* regex.c (init_syntax_once): move below definition of
|
||||
ISALNUM etc., then use ISALNUM to init the table, so that
|
||||
the word ops will work if i18n'ed.
|
||||
(SYNTAX): And subscript with 0xFF for Latin-1 characters.
|
||||
|
||||
1999-10-26 Alain Magloire
|
||||
|
||||
* src/regex.c: Merge changes from GNU lib C.
|

* Updated the *.po files
|
||||
|
||||
1999-10-26 Paul Eggert
|
||||
|
||||
* src/grep.c (fillbuf): Don't report buffer size overflow if
|
||||
newalloc == save and maxalloc == save. This can happen
|
||||
e.g. when reading a large page-aligned file that contains
|
||||
no newlines.
|
||||
|
||||
1999-10-21 Paul Eggert
|

|
||||
Explain exit status more clearly.
|

1999-10-12 Paul Eggert
|
||||
|

* doc/grep.texi: Shorten the commentary about egrep and {.
|
||||
"BSD grep" -> "traditional grep".
|
||||
* doc/grep.1: Match recent changes to grep.texi.
|
||||
|
||||
1999-10-11 Paul Eggert
|
||||
|
||||
* NEWS, doc/grep.1, doc/grep.texi: New option --mmap.
|
||||
* src/grep.c (mmap_option): New variable.
|
||||
(long_options, reset, usage): Add --mmap.
|
||||
Default is now read, not mmap.
|
||||
|
||||
* doc/grep.1: Document -Z or --null.
|
||||
|
||||
1999-10-11 Paul Eggert
|
||||
|

* doc/grep.texi: Fix texinfo glitches. POSIX -> POSIX.2 where
|
||||
appropriate.
|

|
||||
1999-10-11 Paul Eggert
|
||||
|
||||
* acconfig.h (ssize_t): New #undef.
|
||||
|
||||
* configure.in (AC_CHECK_TYPE): Add ssize_t.
|
||||
|
||||
* src/grep.c (PREFERRED_SAVE_FACTOR): New macro.
|
||||
(reset): If the buffer has already been allocated, set bufsalloc to
|
||||
be bufalloc / PREFERRED_SAVE_FACTOR. This avoids problems when
|
||||
bufsalloc == bufalloc (possible after reading a large binary file).
|
||||
(reset): Use PREFERRED_SAVE_FACTOR instead of magic constant.
|
||||
Do not set bufbeg; nobody uses it.
|
||||
Always set buflim.
|
||||
Check for lseek error.
|
||||
Use SEEK_CUR, not a magic constant.
|
||||
(fillbuf): Return an error indication, not a count.
|
||||
All callers changed.
|
||||
Do not assume ssize_t fits in int.
|
||||
Use PREFERRED_SAVE_FACTOR instead of magic constant.
|
||||
Clean up mmap code.
|
||||
Do not attempt to mmap zero bytes.
|
||||
Check for lseek error.
|
||||
Use SEEK_SET, not a magic constant.
|
||||
Work correctly if read is interrupted.
|

(grepfile): Work correctly if open or close is interrupted.
|
||||
|
||||
* src/system.h (SEEK_SET, SEEK_CUR): New macros.

1999-10-02 Paul Eggert
|
||||
|
||||
* NEWS: egrep is now equivalent to `grep -E'.
|
||||
The lower bound of an interval is not optional.
|
||||
You can specify a matcher multiple types without error.
|
||||
-u and -U are now allowed on non-DOS hosts, and have no effect.
|
||||
* doc/grep.texi: Likewise.
|
||||
* doc/grep.1: Likewise.
|
||||
Fix some troff bugs that prevented `groff' from rendering the page.
|
||||
|
||||
* src/egrepmat.c, src/fgrepmat.c, src/grepmat.c (default_matcher):
|
||||
Remove.
|
||||
(matcher): Add.
|
||||
* src/grep.h (default_matcher): Remove.
|
||||
(matcher): Now exported from ?grepmat.c, not grep.c.
|
||||
|
||||
* src/dfa.c (lex): If { would start an invalid interval specification,
|
||||
treat it as a normal character.
|
||||
Remove (broken) support for {,M} meaning {0,M}.
|
||||
Diagnose bogus intervals like {1,0}.
|
||||
(closure): maxrep is now -1 to indicate no limit, not zero;
|
||||
zero is a valid value for maxrep, meaning an upper bound of zero.
|
||||
|
||||
* src/grep.c (short_options): New constant.
|
||||
(long_options, main): -u and -U are now supported on Unix,
|
||||
with no effect.
|
||||
(matcher): Removed; now defined by ?grepmat.c.
|
||||
(install_matcher): Renamed from setmatcher.
|
||||
(setmatcher): New function.
|
||||
(usage): Report new, more uniform option scheme.
|
||||
(main): Do not initialize matcher; ?grepmat.c now does this.
|
||||
Rely on setmatcher to catch matcher conflicts.
|
||||
Default matcher is "grep".
|
||||
|
||||
* src/search.c (matchers):
|
||||
Remove "posix-egrep" matcher; no longer needed.
|
||||
(Ecompile): Likewise.
|
||||
The egrep matcher now has POSIX behavior.
|
||||
|
||||
* tests/bre.tests: grep '\{' is no longer an error.
|
||||
Fix test for interval too large, and enable it.
|
||||
* tests/ere.tests: grep -E {1 is no longer an error
|
||||
Likewise for a{1, a{1a, a{1a}, a{1,x}.
|
||||
|
||||
1999-09-22 Paul Eggert
|
||||
|
||||
* largefile.m4 (AC_SYS_LARGEFILE_FLAGS): Work around GCC
|
||||
2.95.1 bug with HP-UX 10.20.
|
||||
|
||||
1999-09-12 Paul Eggert
|
||||
|
||||
* src/grep.c (fillbuf): Fix typo: we sometimes reported
|
||||
arithmetic overflow even when there wasn't any.
|
||||
|
||||
1999-09-12 Paul Eggert
|
||||
|
||||
* configure.in (AC_CHECK_FUNCS): Add memmove.
|
||||
|
||||
* src/system.h (S_ISREG): New macro.
|
||||
(memmove): Define if ! defined HAVE_MEMMOVE && ! defined memmove,
|
||||
not if !defined STDC_HEADERS. This is needed for SunOS 4.1.4,
|
||||
which defines STDC_HEADERS but lacks memmove.
|
||||
|
||||
* src/grep.c (bufoffset): Needed even if !defined HAVE_MMAP.
|
||||
(reset): Always fstat the file, since we always need its size if it is
|
||||
regular.
|
||||
Similarly, get the buffer offset of every regular file.
|
||||
Set bufmapped to 0 if the file's initial offset is not a multiple
|
||||
of the page size.
|
||||
(fillbuf): Calculate an upper bound on how much memory we should
|
||||
allocate only for regular files, since we don't know the sizes of
|
||||
other files.
|
||||
Don't bother to check whether the file offset is a multiple of the page
|
||||
size, since we now do that just once in `reset'.
|
||||
When an mmapped area would fall past the end of the file, trim it to
|
||||
just before instead of giving up immediately and doing a `read';
|
||||
that avoids a worst-case behavior that could read half an mmapped file.
|
||||
Fix bug when computing offsets on hosts that don't have mmap.
|
||||
|
||||
1999-08-27 Paul Eggert
|
||||
|
||||
* src/system.h (memmove): New macro.
|
||||
|
||||
* src/grep.c (page_alloc): Reallocate the old buffer instead
|
||||
of having both old and new buffers active simultaneously.
|
||||
Remove valloc debugging variant, which no longer applies.
|
||||
|
||||
(fillbuf): Rejigger the buffer allocation mechanism. The old
|
||||
mechanism could allocate more than 10*N bytes for an N-byte
|
||||
file, which was excessive. Check for arithmetic overflow a
|
||||
bit more carefully.
|
||||
|
||||
1999-08-25 Paul Eggert
|
||||
|
||||
* src/grep.c (grepdir):
|
||||
Don't assume that st_ino and st_dev must be integers;
|
||||
POSIX.1 allows them to be floating-point (!).
|
||||
|
||||
* src/vms_fab.h (arr_ptr): `:' -> `;' to fix typo.
|
||||
|
||||
1999-08-18 Alain Magloire
|
||||
|
||||
* 2.3e snapshot.
|
||||
|
||||
1999-08-18 Alain Magloire
|
||||
|
||||
* src/search.c: On a CRAY J90 system running UNICOS 8.0.
|
||||
Compilation of ./src/search.c failed because the declaration of
|
||||
the variable "regex":
|
||||
static struct re_pattern_buffer regex;
|
||||
conflicted with a previous declaration search.c #includes "system.h",
|
||||
which #includes <stdlib.h>, which declares :
|
||||
extern char *regex __((char *_Re, char *_Subject, ...));
|
||||
The declaration in search.c is local to that one source file.
|
||||
I just changed its name to something less likely to conflict.
|
||||
(I called it "regexbuf", but you could pick any name you want.)

||||

|
||||
1999-08-16 Paul Eggert
|
||||
|
||||
Upgrade large-file support to the version used in tar and
|
||||
textutils.
|
||||
|
||||
* Makefile.am (ACLOCAL_AMFLAGS): Define to be empty.
|
||||
(M4DIR, ACINCLUDE_INPUTS): New macros.
|
||||
($(srcdir)/acinclude.m4): New rule.
|
||||
|
||||
* configure.in (AC_CANONICAL_HOST, AM_C_PROTOTYPES): Add.
|
||||
(AC_SYS_LARGEFILE): Renamed from AC_LFS, for compatibility
|
||||
with what should appear in the next autoconf release.
|
||||
|
||||
* m4/largefile.m4: Renamed from m4/lfs.m4.
|
||||
|
||||
* src/ansi2knr.1, src/ansi2knr.c, config.guess, config.sub:
|
||||
New files. config.guess and config.sub ar needed by the new
|
||||
AC_SYS_LARGEFILE. ansi2knr is needed by AM_C_PROTOTYPES,
|
||||
which in turn is needed by the new AC_SYS_LARGEFILE.
|
||||
|
||||
1999-08-16 Alain Magloire
|
||||
|
||||
* 2.3d snapshot on ftp server.
|
||||

||||
1999-07-26 Paul Eggert
|
||||
|
||||
Several GNU tools have options to process arbitrary file names, even
|
||||
file names that contain newline characters. These include `find
|
||||
-print0', `perl -0', `sort -z', and `xargs -0'. It'd be handy if GNU
|
||||
grep also processed such file names. Here's a proposed patch to do
|
||||
this, relative to grep 2.3c. This patch introduces two options, one
|
||||
for the data, and one for the file names. (Sometimes one wants
|
||||
null-terminated file names in the output, and sometimes one wants to
|
||||
process lists of null-terminated strings, and these are orthogonal
|
||||
axes.)
|
||||
|
||||
* NEWS, doc/grep.texi: New -z or --null-data and -Z or --null options.
|
||||
* src/grep.c (long_options, usage, main): Likewise.
|
||||
|
||||
* src/dfa.h (dfasyntax): New eol parameter.
|
||||
* src/dfa.c (eolbyte): New var.
|
||||
(dfasyntax): Set it from new parameter.
|
||||
(lex, dfastat, build_state, dfaexec): Use it instead of '\n'.
|
||||
|
||||
* src/grep.h (eolbyte): New decl.
|
||||
* src/grep.c (eolbyte): New var.
|
||||
(nlscan, prpending, prtext, grepbuf, grep): Use it instead of '\n'.
|
||||
(filename_mask): New var.
|
||||
(prline, grepfile): Output NUL separator if filename_mask is zero.
|
||||
(grep): Look for '\200' as the hallmark of a binary file, not '\0',
|
||||
if -z or --null-data is specified, since it implies that '\0' is
|
||||
expected as text.
|
||||
|
||||
* src/search.c (Gcompile, Ecompile): Pass eolbyte to dfasyntax.
|
||||
(EGexecute, Fexecute): Use eolbyte instead of '\n'.
|
||||

1999-06-15 Alain Magloire
|
||||
|
||||
* src/grep.c, doc/grep{1,texi} :

--revert-match should be --invert-match.
|

Correction proposed by Karl Berry.
|
||||
|
||||
1999-06-12 Alain Magloire
|
||||
|
||||
* doc/grep.{1,texi}: add description for --with-filename.
|
||||
Noted missing by UEBAYASHI Masao.
|
||||
|
||||
1999-03-17 Paul Eggert
|
||||
|
||||
* NEWS: Add GREP_OPTIONS.
|
||||
|
||||
* doc/grep.texi: Document GREP_OPTIONS, and the other
|
||||
environment variables. Fix doc for [:blank:], [:cntrl:], [:punct:].
|
||||
|
||||
* src/grep.c (prepend_args, prepend_default_options): New functions.
|
||||
(main): Use them to implement GREP_OPTIONS.
|
||||
* src/system.h (getenv): New decl.
|
||||
|
||||
1999-03-16 Volker Borchert
|
||||
|
||||
* configure.in: Use case case ... esac for checking Visual C++.
|
||||
When ${CC} contains options it was not recognize.
|
||||
|
||||
1999-03-07 Paul Eggert
|
||||
|
||||
* src/grep.c (usage): Don't report -E, -F, and -G unless we're grep.
|
||||
(main): Don't match options -E, -F, and -G unless we're grep.
|
||||
Remove after-the-fact check for options -E, -F, and -G, since
|
||||
they're no longer needed.
|
||||
|
||||
1999-03-05 Eli Zaretskii
|
||||
|
||||
* src/grep.c (main): Print the name of the default matcher instead
|
||||
of just "grep".

|
||||
1999-02-06 Alain Magloire
|
||||
|
||||
* tests/*.awk : Linux users are seeing "Broken Pipe" on make check.
|
||||
The problem is that grep does not drain its stdin, thus the previous
|
||||
process in the pipeline receives a SIGPIPE. Other shells are silent
|
||||
about this. There is actually no failure, since the broken pipe is
|
||||
expected. You can work around it by changing the pipeline, so that
|
||||
the input is drained, like this:
|
||||
status=`echo 'check' | { ${GREP} -E -e pattern >/dev/null 2>&1;
|
||||
echo $?; cat >/dev/null; }`; if test $status -ne $errnu then ... fi
|
||||

1999-02-23 Alain Magloire
|
||||
|
||||
* src/grep.c : Restrict the use of -E, -F, -G
|
||||
to only grep driver, Posix behaviour. {f,e}grep
|
||||
the matcher is already set. This change may brake
|
||||
scripts, warn in NEWS.
|

|

Fix porting bug reported by Amakawa Shuhei for SunOS 4.1.4-JL.
|
||||
The btowc.c shipped with grep 2.3 is incorrect for Solaris
|
||||
2.5.1 and earlier, as it assumes UTF8, which these OSes do not
|
||||
support. Solaris 7 supports btowc, so there's no need to ship
|
||||
a substitute for it. The only questionable case is Solaris
|
||||
2.6, which lacks btowc but does support UTF8. However, 2.6
|
||||
supports UTF8 but only as a demonstration (for an English
|
||||
locale!); Japanese Solaris 2.6 users typically use EUC, or
|
||||
sometimes shift-JIS, but they cannot use UTF8 since Japanese
|
||||
UTF8 is not supported. Hence there's no point to having grep
|
||||
substitute a btowc that uses UTF8, as it is either redundant,
|
||||
or it will almost invariably have incorrect behavior.
|
||||
|
||||
* configure.in (AC_CHECK_HEADERS): Don't set USE_WCHAR.
|
||||
(AC_CHECK_FUNCS): Add btowc, wctype.
|
||||
(AC_REPLACE_FUNCS): Don't replace btowc; our replacement is
|
||||
invariably doing the wrong thing anyway, at least on SunOS/Solaris.
|
||||
Don't bother to check for wctype in -lw, as we don't support
|
||||
wide characters on Solaris 2.5.1 or earlier anyway.
|
||||
|
||||
* bootstrap/Makefile.try (OBJS): Remove btowc.$(OBJEXT).
|
||||
|
||||
* src/btowc.c: Removed; no longer needed.

Version 2.4:
|
||||
|
||||
- egrep is now equivalent to `grep -E' as required by POSIX,
|
||||
removing a longstanding source of confusion and incompatibility.
|
||||
`grep' is now more forgiving about stray `{'s, for backward
|
||||
compatibility with traditional egrep.
|
||||
|
||||
- The lower bound of an interval is not optional.
|
||||
You must use an explicit zero, e.g. `x{0,10}' instead of `x{,10}'.
|
||||
(The old documentation incorrectly claimed that it was optional.)
|
||||
|
||||
- The --revert-match option has been renamed to --invert-match.
|
||||
|
||||
- The --fixed-regexp option has been renamed to --fixed-string.
|
||||
|
||||
- New option -H or --with-filename.
|
||||
|
||||
- New option --mmap. By default, GNU grep now uses read instead of mmap.
|
||||
This is faster on some hosts, and is safer on all.
|
||||

- You can specify a matcher multiple times without error, e.g.

`grep -E -E' or `fgrep -F'. It is still an error to specify

conflicting matchers.

- -u and -U are now allowed on non-DOS hosts, and have no effect.

Regular expressions are constructed analogously to arithmetic expressions,

@ -631,40 +753,201 @@ In basic regular expressions the metacharacters @samp{?}, @samp{+},

@samp{\|}, @samp{\(}, and @samp{\)}.

In @sc{egrep} the metacharacter @samp{@{} loses its special meaning;

instead use @samp{\@{}. This not true for @samp{grep -E}.

@cindex interval specifications
|
||||
Traditional @command{egrep} did not support the @samp{@{} metacharacter,
|
||||
and some @command{egrep} implementations support @samp{\@{} instead, so
|
||||
portable scripts should avoid @samp{@{} in @samp{egrep} patterns and
|
||||
should use @samp{[@{]} to match a literal @samp{@{}.
|
||||
|
||||
@sc{gnu} @command{egrep} attempts to support traditional usage by
|
||||
assuming that @samp{@{} is not special if it would be the start of an
|
||||
invalid interval specification. For example, the shell command
|
||||
@samp{egrep '@{1'} searches for the two-character string @samp{@{1}
|
||||
instead of reporting a syntax error in the regular expression.
|
||||
@sc{posix.2} allows this behavior as an extension, but portable scripts
|
||||
should avoid it.

@node Usage
|
||||
@chapter Usage
|
||||
|
||||
@cindex Usage, examples
|
||||
Here is an example shell command that invokes @sc{gnu} @command{grep}:
|
||||
|
||||
@example
|
||||
grep -i 'hello.*world' menu.h main.c
|
||||
@end example
|
||||
|
||||
@noindent
|
||||
This lists all lines in the files @file{menu.h} and @file{main.c} that
|
||||
contain the string @samp{hello} followed by the string @samp{world};
|
||||
this is because @samp{.*} matches zero or more characters within a line.
|
||||
@xref{Regular Expressions}. The @samp{-i} option causes @command{grep}
|
||||
to ignore case, causing it to match the line @samp{Hello, world!}, which
|
||||
it would not otherwise match. @xref{Invoking}, for more details about
|
||||
how to invoke @command{grep}.
|
||||
|
||||
@cindex Using @command{grep}, Q&A
|
||||
@cindex FAQ about @command{grep} usage
|
||||
Here are some common questions and answers about @command{grep} usage.
|
||||
|
||||
@enumerate
|
||||
|
||||
@item
|
||||
How can I list just the names of matching files?
|
||||
|
||||
@example
|
||||
grep -l 'main' *.c
|
||||
@end example
|
||||
|
||||
@noindent
|
||||
lists the names of all C files in the current directory whose contents
|
||||
mention @samp{main}.
|
||||
|
||||
@item
|
||||
How do I search directories recursively?
|
||||
|
||||
@example
|
||||
grep -r 'hello' /home/gigi
|
||||
@end example
|
||||
|
||||
@noindent
|
||||
searches for @samp{hello} in all files under the directory
|
||||
@file{/home/gigi}. For more control of which files are searched, use
|
||||
@command{find}, @command{grep} and @command{xargs}. For example,
|
||||
the following command searches only C files:
|
||||
|
||||
@smallexample
|
||||
find /home/gigi -name '*.c' -print | xargs grep 'hello' /dev/null
|
||||
@end smallexample
|
||||
|
||||
@item
|
||||
What if a pattern has a leading @samp{-}?
|
||||
|
||||
@example
|
||||
grep -e '--cut here--' *
|
||||
@end example
|
||||
|
||||
@noindent
|
||||
searches for all lines matching @samp{--cut here--}. Without @samp{-e},
|
||||
@command{grep} would attempt to parse @samp{--cut here--} as a list of
|
||||
options.
|
||||
|
||||
@item
|
||||
Suppose I want to search for a whole word, not a part of a word?
|
||||
|
||||
@example
|
||||
grep -w 'hello' *
|
||||
@end example
|
||||
|
||||
@noindent
|
||||
searches only for instances of @samp{hello} that are entire words; it
|
||||
does not match @samp{Othello}. For more control, use @samp{\<} and
|
||||
@samp{\>} to match the start and end of words. For example:
|
||||
|
||||
@example
|
||||
grep 'hello\>' *
|
||||
@end example
|
||||
|
||||
@noindent
|
||||
searches only for words ending in @samp{hello}, so it matches the word
|
||||
@samp{Othello}.
|
||||
|
||||
@item
|
||||
How do I output context around the matching lines?
|
||||
|
||||
@example
|
||||
grep -C 2 'hello' *
|
||||
@end example
|
||||
|
||||
@noindent
|
||||
prints two lines of context around each matching line.
|
||||
|
||||
@item
|
||||
How do I force grep to print the name of the file?
|
||||
|
||||
Append @file{/dev/null}:
|
||||
|
||||
@example
|
||||
grep 'eli' /etc/passwd /dev/null
|
||||
@end example
|
||||
|
||||
@item
|
||||
Why do people use strange regular expressions on @command{ps} output?
|
||||
|
||||
@example
|
||||
ps -ef | grep '[c]ron'
|
||||
@end example
|
||||
|
||||
If the pattern had been written without the square brackets, it would
|
||||
have matched not only the @command{ps} output line for @command{cron},
|
||||
but also the @command{ps} output line for @command{grep}.
|
||||
|
||||
@item
|
||||
Why does @command{grep} report ``Binary file matches''?
|
||||
|
||||
If @command{grep} listed all matching ``lines'' from a binary file, it
|
||||
would probably generate output that is not useful, and it might even
|
||||
muck up your display. So @sc{gnu} @command{grep} suppresses output from
|
||||
files that appear to be binary files. To force @sc{gnu} @command{grep}
|
||||
to output lines even from files that appear to be binary, use the
|
||||
@samp{-a} or @samp{--text} option.
|
||||
|
||||
@item
|
||||
Why doesn't @samp{grep -lv} print nonmatching file names?
|
||||
|
||||
@samp{grep -lv} lists the names of all files containing one or more
|
||||
lines that do not match. To list the names of all files that contain no
|
||||
matching lines, use the @samp{-L} or @samp{--files-without-match}
|
||||
option.
|
||||
|
||||
@item
|
||||
I can do @sc{or} with @samp{|}, but what about @sc{and}?
|
||||
|
||||
@example
|
||||
grep 'paul' /etc/motd | grep 'franc,ois'
|
||||
@end example
|
||||
|
||||
@noindent
|
||||
finds all lines that contain both @samp{paul} and @samp{franc,ois}.
|
||||
|
||||
@item
|
||||
How can I search in both standard input and in files?
|
||||
|
||||
Use the special file name @samp{-}:
|
||||
|
||||
@example
|
||||
cat /etc/passwd | grep 'alain' - /etc/motd
|
||||
@end example
|
||||
@end enumerate
