Hello,

I have to create a Linux script, this script will execute a loop for each argument. My question is "How to know a how many arguments is received by the script?"

rem: I work with bash.

Thank in advance.

Alain.

The number of arguments on the command line (not counting the script name itself) is automatically stored in the $# variable. For example:

contents of simple_script.bash:

Code:

#!/bin/bash

echo $#

exit 0

[me@host]$ chmod u+x ./simple_script.bash
[me@host]$ ./simple_script.bash 1 2 3 4 5
5
[me@host]$
