in thread Undefined Error

Actually, there is some issue with regex, where I am putting /^BIND$/ to match exact word, as there is another string "UNBIND".

is this not the right way to match exact string /^BIND$/? Please let me know if it is not.

Thanks,

    /^BIND$/ matches if that is the only word on the line.

    Try adding word boundaries \b like this ;

    while (<DATA>){
  if (/\bBIND\b/){
    print $_;
  }
}
__DATA__
this is a BIND sentence
I have UNBIND in this one
BIND as first word
last word is BIND

    BIND seems to be surrounded by spaces, so /\sBIND\s/ should work. Your suggestion would only fit a string (or line) containing BIND and nothing else as the caret is signifying the start of the string (or line) and dollar the end of string (or line).
