The cexp shell is a 3rd party shell package that is not formally part of RTEMS.
A lot of people use it however I do not and do not know anything about it.

I use the shell RTEMS provides in the cpukit/libmisc/shell directory and we have
documented, see docs.rtems.org and click on the shell documents.
To transfer files on to and off boards I set up a machine in the lab as an NFS
server and then mount it in RTEMS using the mount command:
$ cd /
$ mkdir net
$ mount -t nfs foo:/bar /net
If I need to edit text files on a target I add the `edit` shell command. It is
OK at performing small editing tasks on the target. Saving, exiting etc are
mapped to function keys.
I hope this helps.
Chris
