You can also try:
unix: ,>nl
plan9: ,x {
p
} (or write your own nl)
That might do it for larger bodies. Although you have to prepare a
more dedicated script for a clean nl approach.
I like that sam doesn't offer that feature (especially because it
doesn't really need it). It makes you think more about your environment
scripts and how to use/prepare the utilities inside the sam env.
I'm always trying to prepare some sam specific shell/rc scripts and
get my 'missing' features that way. I would appreciate a more clean
nl solution if anyone got something to offer.

Many thanks. I will apply your solutions and revert back. It just seems a little counter intuitive not to be able to show the line numbers as ed does,especially if one is viewing a large body of text. -- 9fans: 9fans Permalink: https://9fans.topicbox.com/groups/9fans/Tc5c492077a61275c-M2a8d78f0b893ede1f6ec5cb3 Delivery options: https://9fans.topicbox.com/groups/9fans/subscription

Re: [9fans] Deleting lines in sam - d
= prints line number
3,7d deletes some lines
Setting and working with the mark may also suit your problem
find a place, press k, find another place, then ',.d or .,' deletes
everything in between. Multiple marks à la ed would be a nice
addition to sam.

[9fans] Deleting lines in sam - d
In ed one can show line numbers using n. To delete line nubers is thus easy. In sam - d it appears this is not possible. I understand sam is not a line editor. What the would be the best way to delete a range of lines? -- 9fans: 9fans Permalink: https://9fans.topicbox.com/groups/9fans/Tc5c492077a61275c-M54374be671082c4e329d2aeb Delivery options: https://9fans.topicbox.com/groups/9fans/subscription

[9fans] acme & sam text selection and delete deletes extra character
Hi there- Please pardon the dumb question if this has been covered before. I did some brief searches of the archive and couldn't find it... I'm running plan9port on macOS. I noticed that in acme, (and also sam) if I select part of a string and p delete, the selection gets deleted and also one additional character in front of the selection. For example, if I type "/path/to/file" and double-click file, file gets highlighted, and if I press delete, "/file" gets deleted leaving me with "path/to". This seems counter-intuitive as I expected only what I had highlighted to be deleted. There is a GitHub issue (#424) https://github.com/9fans/plan9port/issues/424 filed for this as well. Just curious, is this by design, or is this a bug? I'm inclined to think it's by design as it occurs within sam as well. As always, thanks!! -Ben -- 9fans: 9fans Permalink: https://9fans.topicbox.com/groups/9fans/Tf6b94eeff34dd2d7-M674a970ef824d9c5094cb3d7 Delivery options: https://9fans.topicbox.com/groups/9fans/subscription

[9fans] Re: Making multiple changes to dot using sam -d
Hi,
Yep, seems you can combine changes with
,x {
x/sam/c/sam -d/
x/teh/c/the/
}
Adding an optional guard before the opening brace. Note the changes must be
correct way round otherwise you get the error "?changes not in sequence"

I am running sam -d in a Debian Linux Subsystem on Windows. I am editing a series of documents that require several changes per line(s). I can for instance change: I love working in sam in teh terminal to I love working in sam -d in the terminal using: .x/sam/c/sam -d/ .x/teh/c/the Is it possible to combine multiple changes into a single expression?
