Hey guys, I am trying to extract a pattern from a downloaded html file. I only want the first match printed, problem is I don't know how to force sed to exit after printing the first match of a capture group. Anyone know the trick to manipulating {p;q;} to print a capture group?
Thanks, jlc

awk '{if ( $0 ~ /p;q;/ ) { print $0; exit;}}' filename
would work....

Dunno but Google 'sed only first match' gives some answers...

I resorted to just using a perl one liner. It wasn't as straight forward as that. Using sed's {p;q;} syntax with the pattern provides the functionality, but it was the capture group only I was interested, and not the whole line which I couldn't make work with those commands.
Perl was simpler, don't know why I didn't think of that initially.
