[In reply to] Can't Post 1) Using Regular Expressions (perldoc perlre) $foo = 'foo'; $bar = "foo bar bear"; print $bar if $bar =~ /$foo/; Looks for 'foo' in $bar. Prints $bar if 'foo' is found. 2) Using index() (perldoc -f index) $foo = 'foo'; $bar = "foo bar bear"; print $bar if index($bar, $foo)+1; Looks for 'foo' in $bar. Prints $bar if 'foo' is found. ------------------------- NOTE: method 2 is faster but less flexible if you want to do more complex searches.
