Atleast if there was a vi like editor on the box, i could use that to make the changes...
rdfile to read a file, and wrfile to write a file. No fancy editing, but you can read the file with rdfile and the cut-n-paste the corrected version with wrfile. wrfile is very much like the unix `cat` command, except ^C is exit instead of ^D. ^D logs you out of the filer, but doesn't save the file.
rdfile and wrfile are advanced mode commands, so use at your own risk, etc.
