Oh yeah i figured there were some tools able to do that, i meant to say that you can’t substitute one with the other in place without doing some sort of conversion.

sorry for the late reply. I honestly do not remember what the procedure is. The best thing you can do is look on the internet for a easy to follow guide, or wait for someone else’s response

Unfortunately changing from MBR to GPT also deletes existing partitions and partition table, because the two are not compatible.

Luckily, testdisk should be able to recover the old partition table without much fuss, if you didn’t write other data to the disk.

I don’t have a manual handy but the man page from what i remember is pretty clear, and there’s also an online documentation.

There’s no shame in combining multiple tools, that’s what pipelines are all about

Not at all, but some times it’s just funny

You can select specific lines, with regex or by using a line number; or you can select multiple lines by using a comma to specify a range.

Yep, learning this made sed even more useful to me.

I also gave awk a try and now i know what i’ve missed all these years

(Also, sorry for the 12 days old reply :))

12 days late, but thanks for the bit of history, I always enjoy this stuff :)

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.

No viruses is when the gui sucks
