realpath follows all symbolic links encountered for the provided
PATH, printing the absolute path resolved. fish provides a realpath-alike builtin intended to be enrich systems where no such command is installed by default.
If a realpath command exists, that will be preferred.
builtin realpath will explicitly use the fish implementation of realpath.
The following options are available:
- -s or --no-symlinks
Don’t resolve symlinks, only make paths absolute, squash multiple slashes and remove trailing slashes.
- -h or --help
Displays help about using this command.
