i wrote a cpu like client/server for windows (called dos).
my code and test environment lived on a microsoft smb server. i ran cifs(1) to
get access to this from plan9 and sam.
dos(1) allowed me to start an rc(1) running on win32 in the same directory as
my current directory on plan9. it

If you're talking about running the script with ^, it's just an
executable. You can put whatever you want in the shebang line; I tend

I have tested all these solutions and they work. I can now apply the script
(now significantly improved) from within sam and also from the command line
with ssam. I will keep these posts as examples. The only question that remains
is how to add comments to this script. If I use # it is
if you don't already use drawterm anyway for other reasons, and you
only would like to set up ssh, and you already have a working 9p
server for linux (like u9fs), i don't think there's an immediate
benefit in switching to drawterm.
otoh if you already do use drawterm interactively for different
it's still equivalent, obviously you can start drawterm in the
background or in some persistent virtual terminal emulator.
and yes, both drawterm and ssh will use TCP below, the only difference
in the stack for the actual data would be that instead of SSH you
would have TLS for encryption.

yes, if you only need files from the filesystem ssh might be
sufficient protection.

You are right. In that case, the only difference is just that,

if i want to serve files from a linux, i sometimes run drawterm on the
linux, export stuff to an /srv and then access that from the other
side.
theoretically you can automate that also from the other side, make
some script for the /srv stuff, and run it from 9front via ssh via
drawterm:

Just run it like,
fontsrv -s 'tcp!192.168.9.2!1500'
and I've no idea what gitsrv is.
Awesome. Thank you. I can hardly believe you have managed to reduce all those
commands to just a few. I will test this and revert back.

The % is a prompt: ignore it.
I think your script boils down to something like:
,x/\*|^ +| +$/d
,x/ +//c/
,x/[‘‘’’“”‘’]/c/"
,x/\\p|\\b/c/\n\n\n
,x/\n\n+/c/\n

also worth mentioning the ^ command if you're using 9front's sam.
put your sam commands in script like this:
#!/bin/rc
cat << STOP
x/ +/c/
x/\*/d
STOP
then you can run ^script and it will apply the commands.
Note that if you leave off the commas before the commands,
as I have above, you will
Thank you all for your responses. I will carefully study the suggestions
provided. sam is new to me and I am trying hard to learn it. There are obvious
errors in the script I provided and I apologise for those. I could as Rob
suggested simply apply the ed script, but I am trying to learn

you probably want to use ssam (no wq required)
what isn't working? some suggestions:
,x/‘‘|’’/s//"/ and ,x/‘|’/s//"/ → ,x/[“‘’”]/c/"
.x s/\*//g → ,x/\*/d
,x/^ +/s/// → ,x/^ +/d
,x/ +$/s/// → ,x/ +$/d
,x/ +/s// / → ,x/ +/c/ /
take your time, learn the language, & enjoy

There are many things here that feel wrong or at least inelegant, starting
with the first character. Surely you mean a comma not a period. You are
also inconsistent: sometimes you use x to find the pattern and then change
it, sometimes you use a substitute. It's more efficient in both time and
try with ssam(1).

In ed I have a cleanup script which I can apply to several files at once. The
script removes things like blank lines and spaces between words. To run it on a
file or multiple files, I type this command:
ed [name of file(s)] < cleanup-script
I converted all the regular expressions in the file
