#77387 — subprocess module usage

[Multipart message — attachments visible in raw view] — view raw

Hi,

I made simple test program using the subprocess module (see attached:
exec_cmd.py). I ran it passing variations of 'ls' command options.

I encounter exceptions every time I use '-l' options. Example runs
where exception occurs:
# ./exec_cmd.py ls -al
# ./exec_cmd.py ls -l

However, if I pass 'ls' and arguments as one argument, like so:
#./exec_cmd.py 'ls -al'
exception does not occur.

I logged output (see ls_test.out).

So, what could be causing this behavior? Is this expected or is there
something wrong with how I'm using the subprocess module?

Cheers,
Earl
