Changes

* {{Code|proc:system('date')}} returns the current date on a Linux system.

* Analyses the given input and counts the number of lines, words and characters (provided that {{Code|wc}} is available on the system):

proc:system(

'wc', (),

map { 'input': 'A B' || out:nl() || 'C' }

)

* The following example returns “Command not found” (unless {{Code|xyz}} is a valid command on the system):

try {

proc:system('xyz')

'Command not found: ' || $err:description

}

|}

* Instead of the {{Code|proc:code....}} error, the error message will be assigned to the returned element (no process code will be returned).

The result has the following structure:

<result>

<output>...output...</output>

<code>...process code...</code>

</result>
