sys.exit(myString)
doesn't mean "return this string". If you pass a string to sys.exit
, sys.exit
will consider that string to be an error message, and it will write that string to stderr
. The closest concept to a return value for an entire program is its exit status, which must be an integer.
If you want to capture output written to stderr, you can do something like
python yourscript 2> return_file
You could do something like that in your bash script
output=$((your command here) 2> &1)
This is not guaranteed to capture only the value passed to sys.exit
, though. Anything else written to stderr will also be captured, which might include logging output or stack traces.
example:
test.py
print "something"
exit('ohoh')
t.sh
va=$(python test.py 2>&1)
mkdir $va
bash t.sh

Not sure why but in that case, I would write a main script and two other scripts... Mixing python and bash is pointless unless you really need to.
import script1
import script2
if __name__ == '__main__':
filename = script1.run(sys.args)
script2.run(filename)
