To install crypt you can simply rename `crypt.sh` to `crypt` and move it in your path. For example by doing: sudo cp crypt.sh /usr/bin/crypt Similarly to install cryptmenu (which is a dmenu interface) you can do: sudo cp cryptmenu.sh /usr/bin/cryptmenu Note that cryptmenu requires both dmenu and crypt to work. To install the autocomplete scripts you can do something like: sudo cp completion/crypt.bash /usr/share/bash-completion/completions/crypt sudo cp completion/crypt.zsh /usr/share/zsh/site-functions/_crypt
