Question how to debug an expect script running on a tomcat server
Hello everyone,

I have a small expect script as follows;
Code:
#!/usr/bin/expect -f
set force_conservative 0  ;# set to 1 to force conservative mode even if
              ;# script wasn't run conservatively originally
if {$force_conservative} {
    set send_slow {1 .1}
    proc send {ignore arg} {
        sleep .1
        exp_send -s -- $arg
    }
}
set timeout -1
spawn /bin/bash
match_max 100000
send -- "su randeel\r"
expect -exact "su randeel\r
Password: "
send -- "some password\r"
expect "randeel@"
send -- "wine cmd /c wscript Z:\\\\tmp\\\\tomcat6-temp\\\\3fe21de5ca0fe5fb.vbs"
expect -exact "wine cmd /c wscript Z:\\\\tmp\\\\tomcat6-temp\\\\3fe21de5ca0fe5fb.vbs"
send -- "\r"
expect "IRemUnknown_RemRelease"
expect "IRemUnknown_RemRelease"
expect "IRemUnknown_RemRelease"
send -- "\r"
exit
expect eof


when i run this script as another user the above works great!!
But when i invoke the above script from tomcat server(using a java programme to execute the script) as user "tomcat6"
the script doesn't execute fully. How can i debug this issue?
when i issue the command ps -ef;
I see that tomcat6 user has called the script and the process is running.
i also see the bash command also invoked, also i see "su randeel" command also being running.
But i don't know how to debug this issue. I am new to expect,ubuntu.
Any kind of help would be appreciated.

Thank you,
Randeel.

atf-sh

ATF-SH(1)						    BSD General Commands Manual 						 ATF-SH(1)

NAME

     atf-sh [-s shell] -- interpreter for shell-based test programs

SYNOPSIS

     atf-sh script

DESCRIPTION

     atf-sh is an interpreter that runs the test program given in script after loading the atf-sh(3) library.

     atf-sh is not a real interpreter though: it is just a wrapper around the system-wide shell defined by ATF_SHELL.  atf-sh executes the inter-
     preter, loads the atf-sh(3) library and then runs the script.  You must consider atf-sh to be a POSIX shell by default and thus should not
     use any non-standard extensions.

     The following options are available:

     -s shell	  Specifies the shell to use instead of the value provided by ATF_SHELL.

ENVIRONMENT

     ATF_LIBEXECDIR    Overrides the builtin directory where atf-sh is located.  Should not be overridden other than for testing purposes.
     ATF_PKGDATADIR    Overrides the builtin directory where libatf-sh.subr is located.  Should not be overridden other than for testing purposes.
     ATF_SHELL	       Path to the system shell to be used in the generated scripts.  Scripts must not rely on this variable being set to select a
		       specific interpreter.

EXAMPLES

     Scripts using atf-sh(3) should start with:

	   #! /usr/bin/env atf-sh

     Alternatively, if you want to explicitly choose a shell interpreter, you cannot rely on env(1) to find atf-sh.  Instead, you have to hardcode
     the path to atf-sh in the script and then use the -s option afterwards as a single parameter:

	   #! /path/to/bin/atf-sh -s/bin/bash

ENVIRONMENT

     ATF_SHELL	  Path to the system shell to be used in the generated scripts.
