OK, I think I've found what you're looking for: xterm -e "/usr/local/bin/bash --rcfile bash_commands -i" Substitute your program's startup script for "bash_commands" in the above. Using the "-i" switch to bash forces interactive mode, so when the script exits, you'll be returned to the shell prompt in the xterm. As it turns out, xterm's "-hold" switch is wholly unnecessary here. Note that the "--rcfile" switch, being a "double-hyphened" option, must precede the later "-i" switch in order to be recognized.
