removing an entire line	Can't Post

Hello All,

I'm trying to get regex to delete the entire line if it finds 'jpg' anywhere in the line. I'm trying to shrink down my Apache log files.

The closest thing I have come up with is s/jpg/ /

Thank you.

The easiest thing would be to use perl's inplace editing capability:

Code

perl -i.old -ne '/jpg/i or print' access.log

This will make a backup (named access.log.old) of access.log and remove all lines from access.log that contain 'jpg', no matter in which case.
But you can also use the good old grep instead of perl:

Code

grep -iv jpg access.log >access.log.short

Hope this helps.

($">>=1)&1?-hex:hex)+0140)}/./g;$"=chr$";s;.;\u$&;for@_[0,2];print"@_,"
