Binary package “sam” in ubuntu jaunty
the plan9 text editor -- ed with a gui and multi-file editing
sam -d can be used without X (with an ed-like interface -- but with
more powerful regular expressions, the capacity to edit multiple
files with a single command, and unlimited undo). Files can be added
to an exiting sam session using the B command.
sam without the -d option is an graphical editor with pop-up menus
and a point+click interface. You'll want to read sam's manual page to
use the full power of sam, but you can probably figure out how to do
basic editing with a minimum of trial and error.
If you have a Plan 9 terminal, you can use the Plan 9 terminal with
sam to edit unix files, but not vice-versa; the Plan 9 authentication
scheme does not honor remote execution requests from a non-Plan 9
