NAME
savelog - save a log fileSYNOPSIS
savelog [-m mode] [-u user] [-g group] [-t] [-p] [-c cycle] [-l] [-j] [-C] [-d] [-l] [-r rolldir] [-n] [-q] [-D dateformat] file ...DESCRIPTION
The savelog command saves and optionally compresses old copies of files. Older versions of file are named:
file.<number><compress_suffix>
If the file does not exist and -t was given, it will be created.
For files that do exist and have lengths greater than zero, the following actions are performed:
- 1)
- Version numbered files are cycled. Version file.2 is moved to version file.3, version file.1 is moved to version file.2, and so on. Finally version file.0 is moved to version file.1, and version file is deleted. Both compressed names and uncompressed names are cycled, regardless of -l. Missing version files are ignored.
- 2)
- The new file.1 is compressed unless the -l flag was given. It is changed subject to the -m, -u, and -g flags.
- 3)
- The main file is moved to file.0.
- 4)
- If the -m, -u, -g, -t, or -p flags are given, then an empty file is created subject to the given flags. With the -p flag, the file is created with the same owner, group, and permissions as before.
- 5)
- The new file.0 is changed subject to the -m, -u, and -g flags.

BUGS
If a process is still writing to file.0, and savelog moves it to file.1 and compresses it, data could be lost.Contenus ©2006-2024 Benjamin Poulain
