Hi RudiC...

So one is allowed to execute code AFTER exit has been called even if it is an ASCII string inside a variable, from awk AND Python and I thought Python was strict, what about Perl and others?
Awk's exit is a statement and Python's is a function.

Maybe it is just me but this should never be allowed to happen if the RC is not an integer. BTW thanks for the Ctrl-D heads up, I had forgotten all about that, however 'ls -l' is still executed.

Hi Corona688...
It was this, it always needs a redirection to a file for it to work however, so nothing like the other two and technically MUCH safer:-

Code:

Last login: Thu Jun  8 21:10:58 on ttys000
AMIGA:amiga~> exit 10 $( ls -l /tmp/ > /tmp/text )
logout
Saving session...
...copying shared history...
...saving history...truncating history files...
...completed.

[Process completed]

AMIGA:amiga~> cat /tmp/text
total 0
drwx------  3 amiga  wheel  102  8 Jun 18:27 com.apple.launchd.QBBc1cRjqo
drwx------  3 amiga  wheel  102  8 Jun 18:27 com.apple.launchd.iC1FUcCphs
-rw-r--r--  1 amiga  wheel    0  8 Jun 21:12 text
AMIGA:amiga~> _

And yes, I know why the 'text' file_length reads zero, 0.
