[SOLVED] Remove the oldest file of a directory

[aleix]

Hi everybody,

I've have a shell script called by crontab every week.
This script makes a tar file of different files, and save this tar file into a directory.

This directory contains 4 tar files, one of every week since I started to execute the script.

Now I would like to automatically remove the oldest tar file of the directory every time the script is invoqued again.

How can I do that??
Can anyone help me??

Aleix,
Something like this should do what you're describing...
ls -t -r -1 /var/log/kdm.log.* | head --lines 1 | xargs rm

lists the "kdm.log" files in "/var/log", in reverse modificationtime order, one file per line; uses "head" to just pull the first line; then executes the "rm" command.

Similarly, you could do a...
ls -t -1 /var/log/kdm.log.* | tail --lines 1 | xargs rm

which omits the reverse sort and takes the last line as the argument to the rm command.
