Summary
This post shows how to customize $PATH
, an environment variable, in Fish shell.
How-to
Here shows how to add to $PATH
, for example.
1. Set Temporarily
All what to do is run this command:
$ set -x PATH <some-path> $PATH
Well, set
's -x
(or --export
) means it "causes the specified shell variable to be exported to child processes (making it an "environment variable")".
2. Set Permanently
2-1. config.fish
Fish shell has $HOME/.config/fish/config.fish
as .profile
to other shells. Append this line to the bottom of it:
...
+ set PATH <some-path> $PATH
2-2. fish_user_paths
There is another and more "fisher" way. Use its fish_user_paths
, a universal variable of Fish shell.
Open your terminal and run this command:
$ set -U fish_user_paths <some-path> $fish_user_paths
-U
(or --universal
) means it "causes the specified shell variable to be given a universal scope".
Be careful not to write it in config.fish
, which is called every time Fish shell starts.
