This command, unlike all other fish commands, does not feature a -h
|
||
|
|
or --help option. This is because we want to avoid errors on arrays
|
||
|
|
that have -h or --help as entries, which is very common when
|
||
|
|
parsing options, etc. For this reason, the main fish binary does a
|
||
|
|
check and prints help usage if -h or --help is explicitly given to
|
||
|
|
the command, but not if it is the contents of a variable.
