So, I really like Fish - but I need some help with scripting. and in particular finding the path of the script being run.

Here is the solution for BASH Getting the source directory of a Bash script from within

Can anyone help me find the equivalent with fish?

status --current-filename will output the path to the currently executing script.

For more information on the status command, you can run man status or see the documentation at http://fishshell.com/docs/current/commands.html#status

    That prints out the full path to the file. To get the full path to the directory the script is stored in, use `dirname (status --current-filename)`. – Limeth Apr 14 '16 at 15:39

    What if the file is being executed as a symbolic link? `status -f` will print the path of the link, not the actual file. – fiatjaf Dec 25 '16 at 19:59

    Answering myself: `dirname (readlink -m (status --current-filename))` – fiatjaf Dec 25 '16 at 20:02

In fish shell, 

set DIR (cd (dirname (status -f)); and pwd)

is an equivalent to the BASH one liner 

DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"

mentioned in Can a Bash script tell what directory it's stored in?.

NOTE: fish shell will cd into that dir and stay there. Bash will cd but it stays contained in subcommand.

  • For the fish shell, to avoid changing the directory, how about: `set DIR (realpath (dirname (status -f)))` ? – piroux Jul 30 '22 at 13:23

File path

To get the full path of the script, use status --current-filename, or set FILE (status --current-filename) to declare a variable.

Directory path

To get the full path to the directory the script is stored in, use dirname (status --current-filename), or set DIR (dirname (status --current-filename)) to declare a variable.

The equivalent to this question is the following:

set DIR (dirname (status --current-filename)) is the equivalent

  • Using `dirname` directly will only give `.` if run from the same directory, or the directory name if run from another directory. Usually we want an absolute path. – piroux Jul 30 '22 at 13:27

Since readlink -m does not exist on macOS,

DIR=dirname (realpath (status -f))

Works on macOS and Linux at the same time.
This solution also has the benefit to work from an .sh file or even the command line.
