Check if composer is installed and run from bash script












0















I'm trying to create a install.sh script that checks if all my dependencies are installed and then triggers the dependencies scripts.



#!/bin/bash

phpValidation() {
if hash php 2>/dev/null; then
echo 'we have php'
else
echo 'no php'
fi
}

composerValidation() {
if type -t composer ; then #this part does not work
echo 'we have composer'
else
echo 'no composer?!'
fi
}


It works fine for php and yarn, but because composer is an alias it does not get trigged through the script.



How can I check if composer is installed and then trigger it?

  • I would let the user config the cmd (path) used to trigger composer.

  • Just invoke composer and handle the case that it fails.

I found a pretty good script here and modified it to fit my needs.



Here is my simplified version I came up with in the end:



//  Check for composer
composer -v > /dev/null 2>&1
COMPOSER=$?
if [[ $COMPOSER -ne 0 ]]; then
echo 'Composer is not installed'
else
echo 'Composer is installed'
fi
