Here is an example that demonstrates how I would approach something like this:
cat foo.txt
fred barney betty wilma dino
george jane elmo judy
#!/usr/bin/perl -wl
use strict;
# Pull out all those words containg the letter e
my $file = 'foo.txt';
open my $fh, '<', $file or die "Cannot open $file:$!";
my @matches;
while (my $line = <$fh>) {
chomp($line);
my @wanted = $line =~ m/\b(\w*?e\w*?)\b/g;
push @matches, @wanted;
}
print for @matches;
Which prints..
fred
barney
betty
george
jane
elmo
Hope this heps,
Darren :)
