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 cycle-2 is moved to version cycle-3, version cycle-1 is moved to version cycle-2 , and so on. Finally version 0 is moved to version 1, and version cycle 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.
Since the version numbers start with 0, version number cycle is never formed. The cycle count must be at least 2.

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
