How to add composer to a cPanel user's PATH for easier use

Introduction

cPanel provides the dependency manager composer, there are a few steps required for users so they can easily use it through the command line.

Procedure

By default the path the cPanel's provided composer is not present in the PATH environment variable, the path variable is what controls where the shell looks for a program.

To easily add the path you can add the following line to the accounts /home/$USER/.bash_profile file:

source /etc/profile.d/cpanel-php-composer.sh

This appends the path variable to include the path to composer:

# cat /etc/profile.d/cpanel-php-composer.sh

# This script amends the PATH variable for interactive shells so
# that the composer command can be run.
