Tab completion

If you want to use simple tab completion like:

$ texdoc bx[Tab]
bxbase  bxcjkjatype   bxdvidriver  bxenclose   bxjaprnind  bxnewfont   bxpapersize  bxtexlogo
bxcalc  bxdpx-beamer  bxeepic      bxjalipsum  bxjscls     bxorigcapt  bxpdfver

try to write the following line to your .bashrc or .zshrc:

• for bash

complete -W "$(awk '/^name[^.]*$/ {print $2}' $(kpsewhich -var-value TEXMFROOT)/tlpkg/texlive.tlpdb)" texdoc

• for zsh

compctl -k "(($(awk '/^name[^.]*$/ {print $2}' $(kpsewhich -var-value TEXMFROOT)/tlpkg/texlive.tlpdb)))" texdoc
