Calling expect scripts from other expect scripts

Hi,

First, let me explain the issue I am trying to solve. We have a lot of expect scripts with the duplicated send/expect commands. So, I'd like to be able to extract the duplicated code into the common scripts that can be used by other scripts.

Below is my test where I am trying to call b.exp from a.exp:

a.exp
#!/usr/bin/env expect
#
set timeout 5
spawn $env(SHELL)
match_max 100000

send -- "./b.exp $spawn_id\r"

expect "bla"
expect eof
exit

b.exp
#!/usr/bin/env expect
#
set spawn_id [lrange $argv 0 0]
send -- "ls -al\r"
expect bla

I am passing the spawn_id into the b.exp script and then sending the "ls" command. The "ls" command does not output anything, so I understand that I can't pass just like that the handle to the process from one expect script to the other.

Could you suggest any other approach to solve my original issue or maybe there's actually a way to talk to the same process from the distinct expect scripts?

Thanks,
Seva

NAME
dh_installmodules - register kernel modules SYNOPSIS
dh_installmodules [debhelperoptions] [-n] [--name=name] DESCRIPTION
dh_installmodules is a debhelper program that is responsible for registering kernel modules. Kernel modules are searched for in the package build directory and if found, preinst, postinst and postrm commands are automatically generated to run depmod and register the modules when the package is installed. These commands are inserted into the maintainer scripts by dh_installdeb(1). FILES
debian/package.modprobe Installed to etc/modprobe.d/package.conf in the package build directory. OPTIONS
-n, --no-scripts Do not modify preinst/postinst/postrm scripts. --name=name When this parameter is used, dh_installmodules looks for and installs files named debian/package.name.modprobe instead of the usual debian/package.modprobe NOTES
Note that this command is not idempotent. dh_prep(1) should be called between invocations of this command. Otherwise, it may cause multiple instances of the same text to be added to maintainer scripts. SEE ALSO
debhelper(7) This program is a part of debhelper. AUTHOR
