I just wrote a Python script that is going to be called from bash script.
If the Python script fails, I want the bash script to also stop running.
Unfortunately, I can't seem to get that to work. Here's the script so
far:
# custom python script
/usr/bin/python /home/username/Dev/Python/packZODB.py \
-s"gsgmc.sigma.z ettai.net" -b 7
# next program
/usr/bin/someOtherProgra m
I don't want the second program to run if the first program fails. Isn't
that the default in bash? If someone could please point me in the right
direction regarding this problem, I would really appreciate it.
Thanks in advance!

No, that's not the default in bash.
Try:
# custom python script
/usr/bin/python /home/username/Dev/Python/packZODB.py \
-s"gsgmc.sigma.z ettai.net" -b 7
if [ $? -eq 0 ]
then
# next program
/usr/bin/someOtherProgra m
fi
[Yes, I know there are shorter solutions. But his command line is long
enough as it is.]

Have your Python script return a non-zero return code (e.g. sys.exit(1))
when it fails and then have your shell script check for that:
# custom python script
/usr/bin/python /home/username/Dev/Python/packZODB.py \
-s"gsgmc.sigma.z ettai.net" -b 7
if [ $? -ne 0 ]; then
exit 1
fi
# next program
/usr/bin/someOtherProgra m

Hm, not Python but bash related:

someOtherProgra m; fi

I write python command-line programs under Win2k, and I use the bash shell
from Cygwin. I cannot use Cygwin's python package because of a binary
module which has to be compiled with Visual C 6.
My scripts start with a '#!/usr/bin/env python' shebang, as God intended.
Now, I assume I can make cmd.exe run foo.py by asociating *.py with the
python interpreter.

Hi all. I just installed Ubuntu and I'm learning how to use the bash
shell. Aside from the normal commands you can use, I was wondering if
it's possible to use Python from the terminal instead of the normal bash
commands (e.g. print instead of echo). My main reason for asking is that
I like using Python for everything, and if I don't need to learn the
bash 'language', then I won't just yet.
Thanks.

I learned some python in windows.
And now I've turned to linux.
I read a book and it teaches how to write shell script with bash,
but I don't feel like the grammar of bash.
Since I know about python,
I want to get a linux shell which use python grammar.
I searched by google and I found pysh, which is not maintained any
more.
There's another script named pyshell, which is not likely what I'm
searching for.
