终端中的永久源 (Mac OS)

Question

this is probably a very basic question. I am using the bash shell still (Catalina). And I downloaded gromacs. Every time I open a new terminal window I first have to put

source /usr/local/gromacs/bin/GMXRC

in first, otherwise I will just get command not found.

How can I permanently source this so that I don't have to reenter it all the time?

I tried editing the /etc/paths file but that didn't work.

If you are still using the bash shell on macOS , all you have to do is:

Put the line:

source /usr/local/gromacs/bin/GMXRC

at the end in .bash_profile .

.bash_profile is in home directory, so you can open it like:

open ~/.bash_profile

Why.bash_profile?

.bash_profile is executed whenever a login interactive shell starts and on mac, every interactive shell is a login shell by default.

If in case you switch to zsh , instead of .bash_profile , I think .zlogin should be used.

But that would depend entirely on your need. Read about zsh configuration files in case you ever need that.
