Re^2: parse /etc/passwd and output it as csv in hundred servers

THank you what is the meaning of the two lines you added:

$user =~ s/:.*$//mg;
$user =~ s/\n/,/g;

[hippo]

Those are substitutions with regular expressions. The first one removes everything from the first colon to the newline character while the second turns the newlines into commas.

See Pattern Matching, Regular Expressions, and Parsing in our tutorials section, perlretut and perlre in perldoc for some references.

Same thing hippo did but more idiomatic and less readable. :P

say join ",", "hostname", $user =~ /^([^:]+)/gm;
