Re: [9fans] Deleting lines in sam - d
I have applied the script and the suggestions are fantastic. For the kind of work I am doing now, having the numbers helps me a lot, although I do also understand the point Christ is making. Many thanks! -- 9fans: 9fans Permalink: https://9fans.topicbox.com/groups/9fans/Tc5c492077a61275c-M66ddefc2515608e8640fc173 Delivery options: https://9fans.topicbox.com/groups/9fans/subscription
Re: [9fans] Deleting lines in sam - d
I mean, if you really want it, you can
,|awk '{print NR "\t" $0}'
then
,x/^[0-9]+ /d
or something.

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.

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
