Here's a quickie:
use warnings;
use strict;
use File::Find;
my $search_string = "ORA";
find( \&grep, "." );
sub grep
{
my $file = $File::Find::name;
if ( -f $file && -r _ ) {
open( my $fh, "<", $file ) or return;
while ( my $rec = <$fh> ) {
print "Found $search_string in $file"
if $rec =~ /$search_string/;
}
}
}
However, if you have access to Unix, then the following shell snippet might be more useful in the long run:
find . -type f | xargs grep -l ORA
