Do you mean compile as in "Compile into an .exe file" or compile as "execute the script"?

Also, details about what type of system your using will be helpful.
I'm blind.  You put Unix. :(

Try using pp - I haven't used it myself, but it is supposed to be able to create executable Perl files for distribution.

Hi mordi,

Do you mean a simple hello world script to echo on console screen on Unix?  First you need to install perl, which you can download from http://www.perl.com/pub/a/language/info/software.html, then you just need to test first script this way:

perl -e 'print "hello, world\n"'

The script is enclosed in the single quotes, if you want the script to standalone name this code test.pl:


print "hello, world\n";

Then launch the script by typing "perl test.pl" or "./test.pl" if you chmod-ed to 0755 for example.

That's it.  You don't really need to compile a perl program because perl interpreter will do it on-the-fly for you.

mordiAuthor Commented:
could an output of a ls command be printed in the screen from a perl program?
use this code:

open(IN, "ls |"); # open a pipe to read ls command's output
while(<IN>) # read pipe line by line into $_ ($_ is special so you don't need $_ = <IN> syntax
  print; # print line by line (it's printing the default $_ variable, which is storing the line)
