in reply to Pattern match array

This would better be coded using a hash:

use strict; use warnings; my %prims =( "int" => 1, "char" => 1, "long" => 1, "double" => 1, "static" => 1 ); while(<>) { if($prims{$_}) { print "Found item $_\n"; } }
Update:
If you absolutely need to have the @prim array, then create the hash on-the-fly using map:
... my @prim = (("int","char","long","double","static"); my %prim = map { $_ => 1 } @prim; ...
Update2

After reading moritz's take on this, his seems to be what you're looking for.

I was somehow thinking that you were parsing chunks (ie. words) and then seeing if that word existed in your array/hash.

moritz is also spot-on mentioning that you're not handling the newlines at the ends of lines.


Your wish is my commandline.

    But it doesn't do the same thing. aennen searches for substrings, you search for exact matches.

    The fact that the lines aren't chomped means that you'll never get a match (unless on the last line, if it lacks a newline).

    Sorry should have expanded on input.
    Input is source code and I am trying to match
    the pattern in a string of data

    Example input date line

    int EB_Column::beginNPColumn(const bfpd_nc_t& i_rec, BF_COORDINATE_C_D(i_x))
