Description
|
|
-----------
|
|
|
|
:program:`fish_add_path` is a simple way to add more components to fish's :envvar:`PATH`. It does this by adding the components either to $fish_user_paths or directly to :envvar:`PATH` (if the ``--path`` switch is given).
|
|
|
|
It is (by default) safe to use :program:`fish_add_path` in config.fish, or it can be used once, interactively, and the paths will stay in future because of :ref:`universal variables <variables-universal>`. This is a "do what I mean" style command, if you need more control, consider modifying the variable yourself.
|
|
|
|
Components are normalized by :ref:`realpath <cmd-realpath>`. 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 :envvar:`PATH`, so they still stay ahead of the system paths).
|
|
|
|
If no component is new, the variable (:envvar:`fish_user_paths` or :envvar:`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.
|
|
|
|
Options
|
|
-------
|
|
|
|
**-a** or **--append**
|
|
Add components to the *end* of the variable.
|
|
|
|
**-p** or **--prepend**
|
|
Add components to the *front* of the variable (this is the default).
|
|
|
|
**-g** or **--global**
|
|
Use a global :envvar:`fish_user_paths`.
|
|
|
|
**-U** or **--universal**
|
|
Use a universal :envvar:`fish_user_paths` - this is the default if it doesn't already exist.
|
|
|
|
**-P** or **--path**
|
|
Manipulate :envvar:`PATH` directly.
|
|
|
|
**-m** or **--move**
|
|
Move already-existing components to the place they would be added - by default they would be left in place and not added again.
|
|
|
|
**-v** or **--verbose**
|
|
Print the :ref:`set <cmd-set>` command used.
|
|
|
|
**-n** or **--dry-run**
|
|
Print the ``set`` command that would be used without executing it.
|
|
|
|
**-h** or **--help**
|
|
Displays help about using this command.
|
|
|
|
If ``--move`` is used, it may of course lead to the path swapping order, so you should be careful doing that in config.fish.

Example
|
|
-------
|
|
|
|
|
|
::
|
|
|
|
# I just installed mycoolthing and need to add it to the path to use it.
|
|
> fish_add_path /opt/mycoolthing/bin
|
|
|
|
# I want my ~/.local/bin to be checked first.
|
|
> fish_add_path -m ~/.local/bin
|
|
|
|
# I prefer using a global fish_user_paths
|
|
> fish_add_path -g ~/.local/bin ~/.otherbin /usr/local/sbin
|
|
|
|
# I want to append to the entire $PATH because this directory contains fallbacks
|
|
> fish_add_path -aP /opt/fallback/bin
|
|
|
|
# I want to add the bin/ directory of my current $PWD (say /home/nemo/)
|
|
> fish_add_path -v bin/
|
|
set fish_user_paths /home/nemo/bin /usr/bin /home/nemo/.local/bin
|
|
|
|
# I have installed ruby via homebrew
|
|
> fish_add_path /usr/local/opt/ruby/bin
