Category: Extension Modules Group: Python 2.1.1 Status: Open Resolution: None Priority: 5 Submitted By: M. Ibaraki (redmaple) Assigned to: Nobody/Anonymous (nobody) Summary: os.system() and cgi

Initial Comment: This script (test.py) works fine and creates a file 'outputfile' when I run this in test mode (python test.py). --- test.py ---- #!/usr/bin/python import cgi, os print "Content-type: text/html\r\n" print "" print "" ret = os.system('/usr/X11R6/bin/xmgrace -help > outputfile') # ret = os.system('/bin/ls > outputfile') print "

ret = ", ret

It shows:

Content-type: text/html

ret = 0

However, when this is executed as a cgi it shows:

ret = 256

and no 'outputfile' file is created.

Permission of /usr/X11R6/bin/xmgrace is: -rwxr-xr-x 1 root root 450 May 20 18:48 /usr/X11R6/bin/xmgrace

xmgrace is a 2D plotting tool (http://plasma-gate.weizmann.ac.il/Grace/)

I also tried '/bin/ls > outputfile' instead of '/usr/X11R6/bin/xmgrace -help > outputfile'. This 'ls' command is executed and it creates 'outputfile' in both cgi and test modes.

Permission of /bin/ls is: -rwxr-xr-x 1 root root 48316 Sep 15 12:54 /bin/ls

Any comments would be greatly appreciated.
