Question GREP Issue in Perl
Im storing multiple functions in a varaible called $check...
The variable check contains the following:
Code:
a()
b()
c()
...
..etc

now im checking individually which function is kept in which file using GREP
Code:
if ( grep \$check \i, <FILE> )

The problem is im getting the output for the following functions also:
Code:
a(
a();
b(
b();

How to match only a()
Code:
b()
c()

etc..etc..using the grep..

Something like this?

Code:
$ cat input
a()
b()
$ cat input2
b()
$ cat input3
c()

perl code:
  1. #! /usr/bin/perl -w 
  2. use strict;
  3.  
  4. my @check = qw / a() b() c() /;
  5. my @files = glob "input*";
  6. my ($fl, $fn);
  7.  
  8. for $fl (@files) {
  9.     for $fn (@check) {
  10.         open I, "< $fl";
  11.         if (grep {/$fn/} <I>) { print "$fl contains $fn\n" }
  12.         close I;
  13.     }
  14. }

Code:
$ ./test.pl
input contains a()
input contains b()
input2 contains b()
input3 contains c()
