fish_add_path - add to the path¶
fish_add_path [paths...] fish_add_path (-h | --help) fish_add_path [(-g | --global) | (-U | --universal) | (-P | --path)] [(-m | --move)] [(-a | --append) | (-p | --prepend)] [(-v | --verbose) | (-n | --dry-run)] [paths...]
fish_add_path is a simple way to add more components to fish's $PATH. It does this by adding the components either to $fish_user_paths or directly to $PATH (if the
--path switch is given).
It is (by default) safe to use
fish_add_path in config.fish, or it can be used once, interactively, and the paths will stay in future because of universal variables. This is a "do what I mean" style command, if you need more control, consider modifying the variable yourself.
Components are normalized by realpath. This means that trailing slashes are ignored and relative paths are made absolute (but symlinks are not resolved). If a component already exists, it is not added again and stays in the same place unless the
--move switch is given.
Components are added in the order they are given, and they are prepended to the path unless
--append is given (if $fish_user_paths is used, that means they are last in $fish_user_paths, which is itself prepended to $PATH, so they still stay ahead of the system paths).
If no component is new, the variable ($fish_user_paths or $PATH) is not set again or otherwise modified, so variable handlers are not triggered.
If a component is not an existing directory,
fish_add_path ignores it.
--appendcauses the components to be added to the end of the variable
--prependcauses the components to be added to the front of the variable (this is the default)
--globalmeans to use a global $fish_user_paths
--universalmeans to use a universal $fish_user_paths - this is the default if it doesn't already exist
--pathmeans to use $PATH directly
--movemeans to move already existing components to the place they would be added - by default they would be left in place and not added again
--verbosemeans to print the set command used
--dry-runmeans to print the
setcommand that would be used without executing it
--move is used, it may of course lead to the path swapping order, so you should be careful doing that in config.fish.
