Assuming you are using the ``bash`` shell (using ``chsh -s /bin/bash `whoami```), we can create an alias to the relevant commands: ```bash export BASHRC="~/.bash_profile" export PM3LOCAL_PATH="$(greadlink -f .)" touch $BASHRC echo "alias pm3=\'$PM3LOCAL_PATH/pm3\'" >> $BASHRC echo "alias pm3-flash=\'$PM3LOCAL_PATH/pm3-flash\'" >> $BASHRC echo "alias pm3-flash-all=\'$PM3LOCAL_PATH/pm3-flash-all\'" >> $BASHRC echo "alias pm3-flash-bootrom=\'$PM3LOCAL_PATH/pm3-flash-bootrom\'" >> $BASHRC echo "alias pm3-flash-fullimage=\'$PM3LOCAL_PATH/pm3-flash-fullimage\'" >> $BASHRC ``` When you are done running the previous script, make sure to update the settings in your current shell (Mac Terminal) instance by running ```bash source ~/.bash_profile ``` When you re-start the Mac terminal, new shell instances will automatically load these new settings.
