Learning perl

Getting perl running on your system

Installing libraries locally

Download the localbrew script to do everything in one go. The script

  1. downloads cpanm
  2. installs local::lib
  3. creates a shell configuration script (~/.p5env) to set up the environment.

Download it via wget:

wget ''

You can run it via perl Additional modules can be given as parameters:

perl <Mo::du::le::1> <Mo::du::le::2> ... <Mo::du::le::n>

To set up the environment, you have to source the shell configuration:

source ~/.p5env


First thing is to set the install directory of your modules

export PERL_CPANM_OPT="--local-lib=~/perl5"
export PATH="$HOME/perl5/bin:$PATH"

and install cpanminus and local::lib

curl -L | perl - App::cpanminus
cpanm local::lib

Getting the environment right

local::lib gives you a local perl library installation, but you have to set the environment right. Usually you add some variables to the environment settings of e.g. bash (.profile or .bash_profile):

perl -I$HOME/perl5/lib/perl5/ -Mlocal::lib >>$HOME/.profile
echo 'export PERL_CPANM_OPT="--local-lib=~/perl5"' >>$HOME/.profile

Installing perl locally

Sometimes you don’t have perl 5.10 available. But also there is a solution. You can run your own locally installed perl version with perlbrew

curl -kL | bash

source ~/perl5/perlbrew/etc/bashrc

perlbrew available

# for x86
perlbrew install perl-5.10.1 -Dusethreads -Duselargefiles -Doptimize=-O2

# for x86_64
perlbrew install perl-5.10.1 -Dusethreads -Duselargefiles -Dcccdlflags=-fPIC -Doptimize=-O2 -Duse64bitall

Perl & Windows

Currently, the best perl distribution for windows is StrawberryPerl.

Writing better perl code

Put this in every perl script you write

#!/usr/bin/env perl

use warnings;
use strict;

use 5.010;
