trq Posted January 30, 2007 Share Posted January 30, 2007 xargs basically takes standard input and appends it to another commands arguments. So yeah... the command you have does exactly what you want.The first par....[code]ls -t -r -1 /var/log/kdm.log.*[/code]displays all files within /var/log beginning with kdm.log sorted by timestamp, oldest to newest in a single colum. It then pipes the output to the next part.....[code]head --lines 1[/code]which trims the output down to one file (the oldest one), then pipes it to xargs which appends the filename to the arguments of rm and executes it.

neylitalo Posted February 2, 2007 Share Posted February 2, 2007 Please don't title your threads "HELP PLEASE". It's annoying when stuff is in all caps and it's a generic title that tells us nothing.

neylitalo Posted February 3, 2007 Share Posted February 3, 2007 I've attached a screenshot of where it is on my screen - the link says "Topic not solved" because it's currently marked solved.
