[wlug] Bash Hackers’ Wiki

Found this useful collection of Bash tips and tricks. May not be all that well maintained, but I found some handy pages, like this list <https://wiki.bash-hackers.org/scripting/bashchanges> of the more interesting features that were introduced in the various versions of Bash. I was looking for something like this because the Bash version in my Debian Unstable installations was just upgraded to 5.1.
