Grep -v option

[Mark Lockett]

I am trying to parse lines out of a txt file. Instead of running the
command three times, how can I add all the parameters together for the
-v option. Thanks for the help.

This isn't strictly a Perl question. In shell:

$ grep -v x filename | grep -v y | grep -v z

With perl:

$ perl -ne 'print unless /x|y|z/' filename

It sound's like you have some problem with the shell solution, but I
don't know what it might be.

Are you asking about grep or perl? Hint: '|' *may* be what you want in
both cases...

grep(1) is not Perl.

Did you have a Perl question?

Which -v option are you talking about? "perldoc -f grep" doesn't mention it.

egrep allows alternation, no?
