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 [UPDATE, 2011-06-04: I've amplified the script below so it now prints more commonly useful applications. Let's call it LAMPPPR ]:

The result:

Here’s the quickest way to get rolling. Update the second line, then paste it into a terminal:

# Update this variable as appropriate:
MYDIR="~/YOUR_FAVORITE_SCRIPTS_DIR"
cd $MYDIR
wget https://github.com/shuckins/sph_code/raw/master/sysadmin/misc/lamp-info-printer.sh
chmod u+x lamp-version-printer.sh
echo -e "# Prints version info of common applications:\n \
alias lamp='$MYDIR/lamp-version-printer.sh'" >> ~/.bashrc
source ~/.bashrc
lamp

Couldn’t get much 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. Consider the baton passed
