tabset not working when called from expect script

[nkhambal]

I am trying to run tabset from an expect script.My sequence is

• open a new iterm2 tab
• invoke my script to connect to the remote host via ssh
• script tries to run "tabset" commands using "exec" command in expect to set tab parameters
  • exec tabset --color green
  • exec tabset --title $fhost
  • exec tabset --badge $fhost ($fhost is hostname of the remote host stored in variable "fhost")
• next script spawns a session to remote device

However, I don't see the settings of my iterm2 tab changing after running tabset

Am I missing anything? I am using bash shell to invoke the script.

Thanks in advance.
