I posted wrong code for Plan 9 by error.

The E script:
-----------------
#!/bin/rc

files=()
dest=()

if(~ $#* 0){
	echo usage: E file ... >[1=2]
	exit usage
}

for(i)
	switch($i){
	case /*
		files = ( $files $i )
	case *
		files = ( $files `{cleanname `{pwd}^/$i} )
	}

if(test -f /mnt/term/srv/sam.$user) dest = /mnt/term/srv/sam.$user
if not if(test -f /srv/sam.$user) dest = /srv/sam.$user
if not {
	switch($files){
	case *:*
		for(i in $files){
			fi = `{echo $i | sed 's/(.*):[^:]*/\1/'}
			ad = `{echo $i | sed 's/.*:([^:]*)/\1/'}
			plumb -d edit -a 'addr='$"ad'' $fi
		}
	case *
		plumb -d edit $files
	}
	exit
}

switch($files){
case *:*
	for(i in $files)
		echo $i | sed 's/^/B /;s/:(.*)$/\n\1/g' >> $dest
case *
	echo B $files >> $dest
}

The plumb rules:

-----------------

I've tested it in 9front, and all works good. Of course you can delete
all the acme part if you don't use it.

Remember that you have to edit samterm/io.c to create always the pipe

	[...]
		hoststart();
		plumbstart();
		extstart();
	}

And in P9P you need to set the shell to rc in sam/unix.c
	#define SHNAME "rc"
	#define SHPATHNAME "/usr/local/plan9/bin/rc"
	
Or adapt the rules for sh...
