Recursively add directories to $PATH

PATH="${PATH}:$(find ${HOME}/bin -type d | tr '\n' ':' | sed 's/:$//')"
Many users have a personal ~/bin folder for user scripts and other miscellaneous applications they can't or don't want to add to /usr/bin. But this folder can get large and unwieldy. The above command adds ~/bin and all its subdirectories to the PATH environment variable so the scripts can be organized without changing .bashrc.

What Others Think

You can simplify the tr and sed by using paste instead: ... | paste -s -d: Join the lines serially (-s) and use a colon delimiter (-d:) PATH="${PATH}:$(find ${HOME}/bin -type d | paste -s -d:)" You don't *need* the {}s around the env vars, either. PATH="$PATH:$(find $HOME/bin -type d | paste -s -d:)"
