Hello guys

.

I am very new to Perl. I am trying to do my best, but it's difficult for me. Here is my problem: I have a file in a directory /pub/cs/dputnam/cs113a/passwd. The file itself looks like this:

bsulli03:*:32452:5002:barry sullivan,l230,555-6666,:/students/bsulli03

I have to use one or more calls to split() to extract first names from the file. Please help.

I did something:

#!/usr/local/bin/perl
open(NAMES,"/pub/cs/dputnam/cs113a/passwd");
@personal=split(":",$_);
foreach(@personal){
 print"$_\n";
 @next=split(",",$_);
 foreach(@next){
 @after=split(" ",$_);
   print"$_";
  }
}
close NAMES;

but it's not working.

Please, tell me about my mistakes and help me this my work.
