One can create a file named .bash_aliases in their home directory to create aliases for that user.
Is there a way to create a .bash_aliases that is system wide for all users? I know one can add aliases in the /etc/bash.bashrc file but this is not ideal.
And is there a way to achieve this with other shells such as zsh and fish?
You should put the aliases in
/etc/profileor create a file in/etc/profile.d/for them. Most modern shells will source /etc/profile which in turn sources the files in /etc/profile.d/, so that’s the best spot for things like aliases for all users. See the Arch Wiki page Command-line shell, specifically sections 4 and 5.I put a
myaliases.shfile in/etc/profile.d/with all of my aliases and they do not show up in the terminal even after I rebooted my computer.Did you make sure it is a bash script, starting with a shebang, and is executable.
