How can you show different lines with sed?

How can only lines 18,30,45,60 be displayed with the sed command?
Run this command (sed -n -e ‘18,30,45,60p’ example.txt) but show error

Does anyone know how to do it?

Is this your next homework-assignment? :nerd_face:

Teacher to change the question, display lines from 1 to 40, then lines 51,58,61 should be displayed.

sed -n ‘1p…40p;51p;58p;61p’ example.txt

My command did not work
And we are not allowe to write lines from 1 to 40 one by one
Please

Should be sed -n ‘1p-40p;51p;58p;61p’ example.txt

With such a “strict teacher”, you should better learn to query the web properly at first, before diving any deeper into your lessons! :wink:

The search-engine used seems secondary, although I find searx.be the best for any computing-related stuff.

The search keywords are what really matters. You can gather them from the link above and see it is close to what your question was posted in this thread:

sed show specific lines numbers inside text file ...

Why did you delete it?, but I saw it before deleting it
Thankful

Yeah it works. I deleted it because I made a mistake when first testing it myself, and then thinking it was wrong. :v:

According to manpage
sed -n '1~40p;51p;58p;61p' Example.txt

Works just tried. :sweat_smile:

I wouldn’t even find that tilde-key " ~ " on my board, without hastle. Therefore comma " , " also works for line-ranges I guess. :wink:

Your solution is the right one.
Mine refers to lines with distances and does not show the required result.

I just wanted to play along for a moment. Sorry. :blush:
