Stick this in your .bash_profile or .bashrc file: function diffopen() { git diff --name-only "$1" | xargs -d '\n' pstorm; } Then in your project folder, say you want to open all files that differ from your master branch: diffopen master Note, on OSX you’ll need the GNU version of xargs for this to work, as I discovered the hard way..
