wait for prompt then continue

[max1x]

I have to run a set of commands under a special environment with in a shell that changes the prompt. Is it possible to do this in ksh, csh or sh and not have to install Tcl/Expect.

invoke new environment:--> this changes propmt from # to $
Run commands there
Type exit to come to main shell
Parse the data
If needed, reinvoke the 2nd shell
do the above again.

It could be possible if we had a better explanation and didn't have to guess at the requirements (or are they secret?).

why not simply check the value of PS1

if [ "$PS1" = "$" ]
then
  do stuff
fi

then parse your data and repeat as necessary.

LKBrwnDBA:
My current prompt is whoami@dir# - when within a script I have to change shells the prompt becomes whoami@dir $. The script stops here and does not proceed, to execute the commands.

Since the script stops executing at prompt change, I can't run anything, so I can't check prompt settings.

How are you invoking the subshell? How are you specifying the commands to be run within that shell?
