As of fish 2.6.0 conda 4.3.27: the following steps may change as issue is addressed update config Take note of your conda‘s location conda info –root /Users/mstreeter/anaconda # this is my <PATH_TO_ROOT> Add line to ~/.config/fish/config.fish source <PATH_TO_ROOT>/etc/fish/conf.d/conda.fish update convention Typically you’d run the following from bash source activate <environment> source deactivate <environment> Now you … Read more
With the new fishshell (v2.3) you can do set -U fish_prompt_pwd_dir_length 0. And it will use the full path. I also use dartfish for my theme. See example below:
The best way I have found to persistently add a path to your $PATH is set -U fish_user_paths $fish_user_paths ~/path/name This prepends to $PATH. And since it’s persistent, the path stays in $PATH on shell restarts. It’s more efficient than putting a command in your config.fish to modify your $PATH, because it only runs once … Read more
echo a(echo b)c If you have quotes, you must exit them: echo “a”(echo b)”c” If your subcommand may have newlines, as of fish 2.3, you have to save and restore $IFS: set -l IFS echo “a”(cat ~/file.txt)”c” set -e IFS Eventually string will be able to handle this case.
@glenn already got the answer, but I’ve found a simpler way of showing the git prompt on fish. From the terminal, in fish, type fish_config. This will open a browser window. Select the second tab prompt and under there select Classic + Git`. This will show the commands required to show Git on the terminal … Read more
fish isn’t and never tried to be compatible with POSIX sh. This really just means that it’s a separate language (like Java, Python or Ruby) rather than an implementation or extension of sh (like Bash, Dash and Ksh). Obviously, just like you can’t copy-paste Java snippets into a Python program, you can’t copy-paste sh code … Read more
set -q var (note the missing “$” – this uses the variable name) can be used to check if a variable has been set. set -q var[1] can be used to check whether the first element of a variable has been assigned (i.e. whether it is non-empty as a list). test -n “$var” [fn0] (or … Read more
Here are the steps I used to setup the fish shell on my M1 MacBook Air. Per the comments on the question, the key to solving the Unknown Command issue is the fish_add_path: $ brew install fish $ fish $ fish_add_path /opt/homebrew/bin $ echo “/opt/homebrew/bin/fish” | sudo tee -a /etc/shells $ chsh -s /opt/homebrew/bin/fish
In fish, your arguments are contained in the $argv list. Use list slicing to access a range of elements, e.g. $argv[2..-1] returns all arguments from the second to the last. For example function loop –description “loop <count> <command>” for i in (seq 1 $argv[1]) eval $argv[2..-1] end end Usage $ loop 3 echo hello world … Read more
That syntax works in fish too. A demo: $ function cmd1 echo “this is stdout” echo “this is stderr” >&2 end $ function cmd2 rev end $ cmd1 | cmd2 this is stderr tuodts si siht $ cmd1 &| cmd2 rredts si siht tuodts si siht Docs: https://fishshell.com/docs/current/language.html#redirects
