\subsection count-description 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.
|
|
|
|
`count` does not accept any options, including '`-h`'.
|
|
|
|
`count` exits with a non-zero exit status if no arguments were passed
|
|
to it, and with zero if at least one argument was passed.
|
|
|
|
