Mainly
vim /tmp/call.py
Don't use os.system. Use subprocess.
Like in your case:
#bashCommand ="cwm --rdf test.rdf --ntriples > test.nt"
bashCommand ="ls"
import subprocess
#process = subprocess.Popen(bashCommand.split(), stdout=subprocess.PIPE) # we need to split() the command if there are many flags
output = process.communicate()[0]
process = subprocess.Popen(bashCommand, stdout = subprocess.PIPE)
print output # for python2
#print(output) # for python3+
python /tmp/call.py
You will get:
alex@universe /tmp $ python call.py call.py CRX_75DAF8CB7768 fcitx-socket-:0 hsperfdata_alex keyring-StERCr mintUpdate orbit-alex pulse-2L9K88eMlGn7 pulse-PKdhtXMmr18n untitled4897414270208832777.tmp
The output result is the same as the result gotten from BASH
