Very Computer

I want to write a interpreter using ksh, the sample
file needs to be interpreted is something like:

===================================================
TERM Label1 user1 mach1
TERM Label2 user2 mach2

Label1
    uname -a
    pwd
    ... // other Unix commands
Label2
    ...
Label1
    ...
===================================================

Whenever a line with "TERM" at the beginning is read
from the input, the interpreter should be able to emulate
that someone has logged in some machine and started
a session terminal... Take the line "TERM Label1 user1
mach1" for example, the interpreter will "open" a terminal
for user1 at mach1, and labeling this terminal as "Label1",
waiting for commands input ...

Then, all commands below "Label1" are executed in this
terminal ...

I think Unix shell can meet this need. But I have no
idea.  Anyone has a good idea about the implementation
in ksh?

while IFS= read -r line
do
  case $line in
      TERM*) open_term ;;      ## set up terminal emulation
      $SPC*|$TAB*) do_term ;;  ## execute line
      "") ;;                   ## empty line: do nothing
      *) term=$line ;;         ## subsequent lines executed by $term
  esac
done < FILE

    I don't know just what you mean by "emulate that someone has
    logged in", and executing commands in "this terminal", so you need
    to write the functions open_term() to set up the terminal, and
    do_term() to execute the commands.

    Post here with your code and specific problems.
