One Regex match per file

Hello all,

I'm trying to figure out a way to write a Regex statement
(for each
file) where it stops after the first occurrence is
found/matched.

I have tons of files having multiple words having a specific
word
pattern.  I need to just locate the first position of that
pattern in
each file before regex stops searching for THAT file and
moves on to
the next file.

Any ideas?

Thanks,
Todd

Hi, Todd:

you need to tell us which tool you want to use to handle
your problem.
>From my experience, GNU 'awk' has the easiest way:

awk '/pattern/{print FILENAME, FNR; nextfile}' file*

This prints the filename followed by the line_number of the
first
match..

Another way with Perl:

  perl -lne 'print "$ARGV $." and close ARGV
if/pattern/' file*
