LaTeX needs to be compiled twice, instead of running commands over and over do:

for i in `seq 2`; do makeglossaries texfile && bibtex texfile && lualatex texfile.tex ; done

To make LaTex compiling even more simple, use zsh and do:

repeat 2 { makeglossaries texfile && bibtex texfile && lualatex texfile.tex }

Update all git repositories in a given directory

for i in */.git; do ( echo $i; cd $i/..; git pull; ); done
