Handy script: LAMP stack version printer

Often when troubleshooting or setting up servers, I need to know the installed versions of applications commonly grouped into the "LAMP" stack. I dislike having to remember the slight differences between them when trying to coerce each to divulge their version. So I created a script that does that, and even prints it all in easy-to-read colors!

The code:

#!/bin/bash
###################################

# Written by Samuel Huckins

# Prints out version info for
# things in the LAMP stack.
#
###################################
#
echo -e "\e[1;34mThis machine's LAMP stack:\e[0m"
echo ""
# Linux:
LINUX=`cat /etc/issue`
echo -e -n " * \e[31mL\e[1;33minux: \e[0m"
echo "$LINUX"
# Apache:
echo -e -n " * \e[31mA\e[1;33mpache: \e[0m"
if [ -e /usr/sbin/httpd ]
then
echo "`/usr/sbin/httpd -v| head -n 1 | awk '{print $3}'`"
elif [ -e /usr/sbin/apache2 ]
then
echo "`/usr/sbin/apache2 -v| head -n 1 | awk '{print $3}'`"
else
echo -e "\e[37mNot present\e[0m"
fi
# MySQL:
echo -e -n " * \e[31mM\e[1;33mySQL: \e[0m"
if [ -e /usr/bin/mysql ]
then
echo "`/usr/bin/mysql --version | awk '/Ver/ {print $2, $3, $4, $5}' | sed 's/,//'`"
else
echo -e "\e[37mNot present\e[0m"
fi
# PHP:
echo -e -n " * \e[31mP\e[1;33mHP: \e[0m"
if [ -e /usr/bin/php ]
then
echo "`php -v`"
else
echo -e "\e[37mNot present\e[0m"
fi
# Perl:
echo -e -n " * \e[31mP\e[1;33merl: \e[0m"
if [ -e /usr/bin/perl ]
then
echo "`perl -v | awk '/This is perl/ {print $4}' | sed 's/v//'`"
else
echo -e "\e[37mNot present\e[0m"
fi
# Python:
echo -e -n " * \e[31mP\e[1;33mython: \e[0m"
if [ -e /usr/bin/python ]
then
echo "`/usr/bin/env python -V 2>&1 | awk '/Python/ {print $2}'`"
else
echo -e "\e[37mNot present\e[0m"
fi
# done
echo ""

The result:

Call it "lamp-version-printer.sh", and add something like "alias lamp="~/my/code/lamp-version-printer.sh". Couldn't be easier.

Minor caveat: While the script does check each program for existence, I only check the most common place. It could be better expanded to cover less used locations for applications, conventions on more OSes, etc.
