Question Help with md5 in PERL
I am a newbie in programming in Perl.

My problem is that this unix command is embedded in Perl but it gives an empty output. Here's the code:

Code:
$temp = `md5 "../Directory String/..." | awk {'print $NF'} > "../Directory/file.txt"`;

The output file should contain the md5 hash value of the ".../Directory String/.." but rather it outputs a zero byte file. Smilie

  1. I believe the command is called md5sum, not md5
  2. $NF prints the last field, which usually is the name of the file the sum belongs to
  3. Take a look at Digest::MD5 and save yourself some trouble calling external programs

It should be:
Code:
awk '{print \$NF}'
