Are you opposed to using awk?

Not at all, I’m just not familiar with it so I find it confusing.

Although, looking at your command, i think I understand what it means

I see. I guess what confused me was that i didn’t understand what addresses were.

Thank you for your explanations :)

I meant to ask what is the difference between, i.e., sed '/myregex/ s/from/to/ p' and sed '/myregex/ s/from/to/ ; p', but while testing to explain what i meant I answered myself, and in the process I also understood what addresses are ehe

Right, awk is a proper programming language, right? that’ll be for another day…

!/dev/dm-2!!p

This weired me out until I read the explanation. I’m so used to the slashes lol

In the end I’ve used the first command you wrote, because KISS, but I appreciate your explanation

Check the sed man page for more details

Yes that’s been my only source so far, but to be honest it’s really cryptic. it might just be that I’m used to syscalls man pages (also sed is language so it can’t be easy to write a single man page for it)

The -n suppresses auto-printing

That’s something I was missing! It makes the command look definitely less complicated.

Also, what is the difference between separating expressions with a space vs with a semicolon?

Easier IMHO is awk

Eh, that’s another beast. For some reason tho I find sed more appealing.
