AFAIK - grep returns the number of matches in scalar context and the actual matches in list context - not the "row" at which it matched.
For this, you will need to loop over your array - using both indices - something like the following untested code:
#!/usr/bin/perl -w
use strict;
my @array = (); #actually use code that creates 2d array
for ( my $i = 0; $i <= $#array; $i++) {
for ( my $j = 0; $j <= $#{$array[$i]}; $j++ ) {
if ($array[$i][$j] =~ /something/) {
# Do something with $array[$i][$j]
}
}
}
Hope this helps point you in the right direction. I really like our Q/A section at PM, the http://www.perlfaq.com FAQ, and the http://www.perldoc.com FAQ.
Cheers - L~R
Update: Code now tested. As others have shown, if you do not need the indices and need only the row - other methods work with grep.
