Autocomplete
At ksh there is a way to add auto completion
Use my new installer which installs the newest version of the .ksh_completions file into all of your users:
$ wget -O ksh-completion-installer.sh "https://gotweb.ircforever.org/cgi-bin/gotweb/gotweb?path=ksh-completion.git&action=blob&commit=1d3af82c873d57cf5e06319537281bef28ba1522&file=install.sh"
$ ksh ksh-completion-installer.sh
