Regarding Python Program with Shell Script
Hi All,

I have written a shell script which is using the expect method, it is working fine in terminal window, and then I have executed via python script its also working fine in command prompt functioning properly, I used subprocess.Popen method to execute the shell script file, its working fine in terminal window, when I try to execute via web browser it says that error "send: spawn id exp3 not open while executing "send -- "pwd\r"" (file "/var/www/Site/test.sh" line 5). the same is executing from command line (ie) python /var/www/Site/test.py it executes perfectly

Below is my shell script and python script

Code:
#!/usr/bin/expect -f
#!/bin/bash
spawn command
expect "Password:"
send -- "pwd\r"
send -- "\r"
expect eof

#below is my python script to execute the shell script files
Code:
#!/usr/bin/python
import MySQLdb
import subprocess
import pexpect
import cgi
import sys
import os
import urllib
import cgitb
import Cookie

try:

Code:
command="/var/www/Site/test.sh"
proc=subprocess.Popen(command,stdout=subprocess.PIPE,stderr=subprocess.PIPE)
(stdout,stderr)=proc.communicate()
if stderr:
print "Content-type:text/html\n\n Fail: "+command+str(stderr)
else:
print "Content-type:text/html\n\n Success"+command
except:
e=sys.exc_info()[1] 
print "Content-type:text/html\n\n fails"+str(e)

Thanks in advance

Thanks
Jana

idle

IDLE(1) 						      General Commands Manual							   IDLE(1)

NAME

       IDLE - An Integrated DeveLopment Environment for Python

SYNTAX

       idle [ -dins ] [ -t title ] [ file ...]

       idle [ -dins ] [ -t title ] ( -c cmd | -r file ) [ arg ...]

       idle [ -dins ] [ -t title ] - [ arg ...]

DESCRIPTION

       This  manual page documents briefly the idle command.  This manual page was written for Debian because the original program does not have a
       manual page.  For more information, refer to IDLE's help menu.

       IDLE is an Integrated DeveLopment Environment for Python. IDLE is based on Tkinter, Python's bindings to the Tk widget  set.  Features  are
       100%  pure  Python, multi-windows with multiple undo and Python colorizing, a Python shell window subclass, a debugger. IDLE is cross-plat-
       form, i.e. it works on all platforms where Tk is installed.

OPTIONS

       -h     Print this help message and exit.

       -n     Run IDLE without a subprocess (see Help/IDLE Help for details).

       The following options will override the IDLE 'settings' configuration:

       -e     Open an edit window.

       -i     Open a shell window.

       The following options imply -i and will open a shell:

       -c cmd Run the command in a shell, or

       -r file
	      Run script from file.

       -d     Enable the debugger.

       -s     Run $IDLESTARTUP or $PYTHONSTARTUP before anything else.

       -t title
	      Set title of shell window.

       A default edit window will be bypassed when -c, -r, or - are used.

       [arg]* and [file]* are passed to the command (-c) or script (-r) in sys.argv[1:].

EXAMPLES

       idle   Open an edit window or shell depending on IDLE's configuration.

       idle foo.py foobar.py
	      Edit the files, also open a shell if configured to start with shell.

       idle -est "Baz" foo.py
	      Run $IDLESTARTUP or $PYTHONSTARTUP, edit foo.py, and open a shell window with the title "Baz".

       idle -c "import sys; print sys.argv" "foo"
	      Open a shell window and run the command, passing "-c" in sys.argv[0] and "foo" in sys.argv[1].

       idle -d -s -r foo.py "Hello World"
	      Open a shell window, run a startup script, enable the debugger, and run foo.py, passing "foo.py" in sys.argv[0] and "Hello World" in
	      sys.argv[1].

       echo "import sys; print sys.argv" | idle - "foobar"
	      Open a shell window, run the script piped in, passing '' in sys.argv[0] and "foobar" in sys.argv[1].
