TMPWATCH(8) System Administrator's Manual TMPWATCH(8)
tmpwatch - removes files which haven't been accessed for a period of time
tmpwatch [-u|-m|-c] [-faqstv] [--verbose] [--force] [--all] [--test]
[--fuser ] [--atime|--mtime|--ctime] [--quiet] <hours> <dirs>
tmpwatch recursively removes files which haven't been accessed for a given number of
hours. Normally, it's used to clean up directories which are used for temporary holding
space such as /tmp.
When changing directories, tmpwatch is very sensitive to possible race conditions and will
exit with an error if one is detected. It does not follow symbolic links in the directo-
ries it's cleaning (even if a symbolic link is given as its argument), will not switch
and only removes empty directories and regular files.
By default, tmpwatch dates files by their atime (access time), not their mtime (modifica-
tion time). If files aren't being removed when ls -l implies they should be, use ls -u to
examine their atime to see if that explains the problem.
If the --atime, --ctime or --mtime options are used in combination, the decision about
deleting a file will be based on the maximum of this times.
The hours parameter defines the threshold for removing files. If the file has not been
accessed for hours hours, the file is removed. Following this, one or more directories
may be given for tmpwatch to clean up.
Make the decision about deleting a file based on the file's atime (access time).
This is the default.
Make the decision about deleting a file based on the file's mtime (modification
time) instead of the atime.
Make the decision about deleting a file based on the file's ctime (inode change
time) instead of the atime; for directories, make the decision based on the mtime.
Remove all file types, not just regular files and directories.
Do not attempt to remove directories, even if they are empty.
Remove files even if root doesn't have write access (akin to rm -f).
Doesn't remove files, but goes through the motions of removing them. This implies
Attempt to use the "fuser" command to see if a file is already open before removing
it. Not enabled by default. Does help in some circumstances, but not all.
Dependent on fuser being installed in /sbin.
Print a verbose display. Two levels of verboseness are available -- use this option
twice to get the most verbose output.
cron(1), ls(1), rm(1), fuser(1)
GNU-style long options are not supported on HP-UX.
