[9fans] Filename Referencing in Sam

[yard-ape]

Sam experts:

Are there any simple ways to use the current filename as material inside the command language?  For example, how might I insert a file's filename as a title at it's first line?  Or, how might I run a shell command (using "!") on a file with it's filename as an argument to the command?

I can do these kind of things manually with the mouse, of course, but it would be nice to be able to do it inside loops and tests (with "X", "Y", "x", "y", "g", etc).  If it helps clarify, what I'm *used* to using for this sort of thing is a filename variable (like "%" in many implementations of ed).

Thanks!

I added this to the plan9port sam over the summer.
The name of the current file is exported as $samfile.

The code hasn't made it into Plan 9 but if you want it,
see the top of http://swtch.com/usr/local/plan9/src/cmd/sam/shell.c

Thanks, Russ.  I've been wanting something like that for a long time.
