count

NAME

count - count the number of elements of an array

Synopsis

count $VARIABLE

Description

count 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 program, 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 be passed on to the count program.

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'.
