Enoexec
which executes a shell using subprocess.Popen(command.split()) where command is string which constitutes .sh script and its argument. This script was working fine till yesterday. Today, I ran the same script and now i am contiguously hitting by this error. p=subprocess.Popen(shell_command.split()) File "/usr/lib/python2.7/subprocess.py", line 679, in __init__ errread, errwrite) File "/usr/lib/python2.7/subprocess.py", line 1249, in _execute_child raise child_exception OSError: [Errno 8] Exec format error I know there are similar questions has been asked before related to this question. call shell script from python But, in my case i tried everything which doesn't solve my purpose. Using shell=True is not able to work because my shell script calls an another shell script before which some environment has to be set in order to ran that script. I am badly stuck in this. ?? I just restart my system once. I am using ubuntu 12.04 EDIT: import subprocess import os import sys arg1=sys.argv[1] arg2=sys.argve[2] shell_command = 'my_path/my_shell.sh ' + arg1 + ' '+ arg2 P = subprocess.Popen(shell_command.split()) P.wait() my_shell.sh: arg1=$1 arg2=$2 cd $TOP setup the environment and run shell script build the kernel ... execute shell command ..... python linux shell share|improve this question edited Nov 7 '14 at 19:13 asked Nov 7 '14 at 18:42 Amit Sharma 8211516 Have you tried import shlex and using shlex.split(shell_command)?

sagark was assigned Sep 1, 2012 Owner sagark commented Sep 1, 2012 Everything from the 2nd line on is normal - it just means that those resolutions have been added to xrandr already and it likes to complain when that happens (but no harm done). The first looks like a problem though, I'll look into it. Owner sagark commented Sep 1, 2012 Ok, I've attempted a fix. I can't replicate the error on my machine so can you try this out?
