Replace all existing copyright headers with `SPDX` headers I've used the following command to replace the original copyright header lines in a C-style comment block: ``` $ find . \( -type d \( -name '\..' -o -name third-party -o -name scripts -o -name prefix -o -name malloc -o -name server -o -name docker -o -name build -o -name doc \) -prune \) -o -type f -exec perl -pi -e 's{/\[^]\(\sc\s\)\s(\d{4})\sIcinga\s+GmbH[^]\/}{// SPDX-FileCopyrightText: \1 Icinga GmbH <https://icinga.com>\n// SPDX-License-Identifier: GPL-2.0-or-later}gi' {} + ``` For files that use shell-style comments (#) like CMakeLists.txt, I've used this command: ``` $ find . \( -type d \( -name '\..' -o -name third-party -o -name scripts -o -name prefix -o -name malloc -o -name server -o -name docker -o -name build -o -name doc \) -prune \) -o -type f -exec perl -pi -e 's{#.\(\sc\s\)\s(\d{4})\sIcinga\s+GmbH.}{# SPDX-FileCopyrightText: \1 Icinga GmbH <https://icinga.com>\n# SPDX-License-Identifier: GPL-2.0-or-later}gi' {} + ``` And for SQL files: ``` $ find . \( -type d \( -name '\..' -o -name third-party -o -name scripts -o -name prefix -o -name malloc -o -name server -o -name docker -o -name build -o -name doc \) -prune \) -o -type f \( -name '.sql' \) -exec perl -pi -e 's{--.\(c\)\s(\d{4})\sIcinga\sGmbH.}{-- SPDX-FileCopyrightText: \1 Icinga GmbH <https://icinga.com>\n-- SPDX-License-Identifier: GPL-2.0-or-later}gi' {} + $ find . \( -type d \( -name '\..' -o -name third-party -o -name scripts -o -name prefix -o -name malloc -o -name server -o -name docker -o -name build -o -name doc \) -prune \) -o -type f \( -name '.sql' \) -exec perl -pi -e 's{-- Copyright \(c\)\s(\d{4})\sIcinga\s+Development\sTeam.*}{-- SPDX-FileCopyrightText: \1 Icinga GmbH <https://icinga.com>\n-- SPDX-License-Identifier: GPL-2.0-or-later}gi' {} + ``` 2026-01-27 09:06:40 -05:00			`// SPDX-FileCopyrightText: 2012 Icinga GmbH <https://icinga.com>`
