hi, can anyone helpme, when i send the tar command, i get this:
Code:Removing leading `/' from member names
when i look at my directory, i see that the tar has been created, but i was wondering if this is going to cause a problem when i try to untar it since this is going to be a back up file and if there any goes wrong, i want to make sure i am doing it right. not sure if i executed incorectly on my linux server.
thanks

this is what that post says:
he "Backup Ideas" page[1] has an example shell script meant to be executed as a daily cron job.
That example includes an invocation of the tar command like this:
tar cj /etc /home/ /usr/local > $PREF-$$.tar.bz2
If you run a script containing a tar invocation of that form, you'll notice that root will get an e-mail message every time the script runs, with stderr warnings from the tar command saying "Removing leading `/' from member names".
You can eliminate those tar warnings by instead invoking the tar command like this:
tar cj -C / etc home usr/local > $PREF-$$.tar.bz2
The effect will be the same except that tar will no longer emit the "Removing leading `/' from member names" warnings to stderr -- because the -C option and slash argument tell tar to cd to the root directory before tarring up whatever directories or files are specified in the rest of the arguments list.
So you'll no longer get the unnecessary mail from that cron job -- you'll only get mail if something has actually gone wrong with the job.
