Question Bourne shell input from file using < then return control to user?


Hi all,

I have a program that I run from the terminal that requires manual input (it's matlab in mex debugging mode, matlab -Dgdb, which starts the GNU C debugger with its own custom settings).

Every time I run this program I always type in the same few commands in the program's interactive shell before I actually start working (for example: run -nojvm; stop at mexFunction; continue). I want to avoid typing these commands and I thought I could do this with shell scripting, saving the commands in the mycommands file, then running:

myprogram < mycommands

The problem is that this runs all the commands and then exits the program. I want it to run the commands and return control to me so I can run my commands. Is there a way to tell the shell to use a file or a string as the input to a program then immediately return control to the user without the exiting the program?

not really
you might be able to change the program config to read the file on start and perform those steps
but the shell will only ever run the program until the end of the file then terminate it.

I am not sure of all its workings, but you might have a look at expect as a possible solution.

Thanks, I suspected it might be a bit involved.
