Hi ,
I am a pretty intermittent user of perl , i am trying to
write a subroutine to search for a pattern in a file , which
i will call multiple times based on the need. But i seem to
have made some mistake as the script just gets stuck.
Can i please get some pointers on how to proceed
&find_pattern($dir1);

sub find_pattern
{
 my $file3="/etc/filesystems";
 my $pattern = $_;
 my $result = `grep $pattern $file3`;
 if ($result) {
 print "Entry for $pattern is updated in $file3/n!";
 } else {
 print "Entry for $pattern not found in $file3/n!";
 }
 return;
}
