[Script] - wp-auto.sh

ARCHIVED POST - This is old, links might not work

While far from complete, this bash script was created for a variety of reasons. The idea developed when localwp refused to install on my system due to a dependency issue libncurses5.

After briefly searching github nothing really seemed to pop out as a functional alternative. Given I just recently had my knee operated on, I figured it would be a good opportunity to learn more about bash scripting while creating something functional.

I’d never actually scripted with getopts either. And to make things even harder, I figured I’d try to write it POSIX compliant..

I’ll be updating the project at the github repository https://github.com/DTRHnet/wp-auto, so if you are seeing this there is a good chance it’s been updated since. Check it out.

This script has yet to incorporate -v, -l log.file, -c flags. That means adding verbosity, writing to a log file or disabling colour are non functional
This script does not yet create sql databases. In fact, due to my distro, I’ve disabled the MySQL installation and have yet to write SQL database configurations

I’ll get around to working more on this when I can walk across the room to my actual computer.
