Thank you again for pointing this out! I use ack several times a week,
if not daily. It has saved me from having to
Thank you for all the great solutions!
Because of my extremely limited *nix knowledge, I'd use the approach of two
grep's in a pipeline, such as the one grep '^\*' yourFile | grep -v
'^\*INDICATOR' suggested by Michael, as it's simple to understand and easy
to memorize.
Thank you again.

Cool. By default ack ignores plain text files, so you have to tell it to
include them even when explicitly specifying the

GNU egrep 2.5.1 doesn't work:

You need to specify -P (or --perl) to turn on support for Perl
regular expression extensions.Otherwise it will interpret the (?

Hi,
I have a text file whose content looks like below:
*INDICATOR name1 zip1
geoid gender location
*INDICATOR name2 zip2
*geoid gender location
INDICATOR name3 zip3
*district court
I want to pick up all lines starting with * but no INDICATOR
followed.
So for the example above, I want to pick
grep '^\*' yourFile | grep -v '^\*INDICATOR'

I'm not sure how you'd combine them into one REGXP.
I'm sure there's a better way in perl (GNU egrep will do perl with -P)

I'd double-grep it, but i'm not infront of a *nix box to check
grep -i * | grep -v *INDICATOR filename
or something to that effect.

That didn't work for me, but this did:
egrep '^\*[^I][^N][^I][^D][^I][^C][^A][^T][^O][^R]' filename.txt

Assuming your grep supports the Perl regular expression extensions
(a useful thing to have), that should work.

ack is pure Perl, so consistent across all platforms. Command
