I am using a Tcl script to change the poller password through spawning the telnet command. I have done this with the script below, and tested it on a Windows machine after installing ActiveTcl8.5.13.0.296436-win32-ix86-threaded

spawn telnet $serNumber $pNumber
#flush stdout
expect ">"

send "Clients\r"
expect ">"

send "1\r"
expect ">"

send "Pollers\r"
expect ">"

Now I want to run same script in a Linux machine, but as I am new to Linux systems, can anybody help me that how to install tcl in linux system and get executed the same script there?

Any help is a great for me. Please provide any useful links.

    What Linux distribution are you using, or are you rolling your own? This affects what answer is best for you... – Donal Fellows Apr 16 '13 at 16:09
  • @Jerry - tcl is in-built for linux? i am new to linux system. if it's in-built. so what is command to execute script there. i mean in windows i am running like `tclsh filename.tcl` – Piyush Apr 16 '13 at 16:22
  • I have a Linux Mint where I have run tcl scripts using `tclsh filename.tcl` in the bash. I don't have other versions of Linux though. – Jerry Apr 16 '13 at 16:24
  • Tcl is often preinstalled. Otherwise use your favorite package manager to install tcl and expect. – Johannes Kuhn Apr 16 '13 at 16:29

You're in luck. RHEL 4 has expect in its repositories. You can simply install it with yum:

yum install expect

and it should install expect and all its dependencies.

You're not using Tcl, you're using expect, which is a separate program which just happens to use Tcl. To install it, do

apt-get install expect

Note that the above command is a guess as you did not tell us which Linux-based OS you're using ("Linux" is not an OS, it's just a kernel).

If you have no one to ask which system you're running, post the results of running the following commands:

uname -a
lsb_release -a
cat /etc/issue

so we could try to make an educated guess.

To install Tcl on Linux (I'm using RedHat), you can do 

yum install tcl

And you will get the most recent version of tcl.
