Hello. Recently a friend of mine, who is learning programming in university for a master degree asked me to help writing a script for unix that matches a C file and opens it for reading or writing. Here is my suggested script: 

#!/usr/bin/perl
use warnings;
use utf8;
use strict;

my $arguments = shift;
if ( system("gcc $arguments") == 0) { #can we complie the file?
    print "C file.. opening... \n";
    open (FH, '<', $arguments) or die("No file: $!\n");

    while ( <FH> ) {
        print $_; #read it, edit it or whatever needed
        }
        }
else {
    print "Not a C file\n";
    }

I know that you`d suggest doing a search in file such as regex search or .c match, it`s true but actually you can`t be that verbose if it`s C file by just matching #include<stdio.h> or int main(void)... So I suggested to try compling it -- if it succeeds it`s a C file if it fails it`s other one. Opinions?
