Title: egrep regular expression to remove a matching line
Post by: John_L. on February 15, 2016, 06:59:04 PM

To my way of thinking,

Code: [Select]

egrep -x -e '(.*errorlog.txt.*){0}' dir.txt
should remove a line containing "errorlog.txt" (anywhere in the line) from the input file. But it is not so. If fact, it matches ??? only the line containing "errorlog.txt".

Can I utilize egrep to accomplish this task, and if so, what regular expression must I use?

Thanks  in advance.
