Shell Information

The ROTSE User Shell (rush) is a fully functional shell environment, and can run executables, shell scripts, perform file manipulation, etc. In addition, there are many ROTSE-specific built-in functions that are described in this chapter. Built-in functions can be used from any directory, and from any shell script.

For each command that operates hardware, after the command is issued control is returned to the shell. Execution of the command may take some time. Monitoring the status with rstat reveals when the command has finished. If you issue a command with the -w wait option, the shell will block until the command has finished.
