Let's say I run a command in bash which is run via konsole. How can I view its exit status.

For example, if I do

$test -x debian/rules

I want to know if the command exited with status zero or non-zero. Can this be done in a simple way?

thank for any suggestions
raju

$test -x debian/rules; echo $?

man bash:
Special Parameters
(...)
? Expands to the status of the most recently executed foreground
pipeline.

Here's a $0.02 recipe from my ~/.bashrc:

if [ "$PS1" ]; then
PROMPT_COMMAND='echo -n "$? "'
fi

This way, an interactive bash will print the exit status of the last
command before its prompt, so you can _always_ see it. Very handy,
IMO. :-)

Cheers,
Sven
