NAME
count - count the number of elements of an array
Synopsis
count $VARIABLE
Description
The count builtin prints the number of arguments that were passed to
it. This is usually used to find out how many elements an environment
variable array contains, but this is not the only potential usage for
the count command.
The count command does not accept any options, not even '-h'. This way
the user does not have to worry about an array containing elements such
as dashes. fish performs a special check when invoking the count
command, and if the user uses a help option, this help page is
displayed, but if a help option is contained inside of a variable or is
the result of expansion, it will simply be counted like any other
argument.
Count exits with a non-zero exit status if no arguments where passed to
it, with zero otherwise.
Example
count $PATH
returns the number of directories in the users PATH variable.
count *.txt
returns the number of files in the current working directory ending
with the suffix '.txt'.
