Remove first and last line of output with sed (maybe a better way)

[cj13579]

HI all,

I'm getting really frustrated with this so I was wondering whether someone can help me out? I am am trying to remove the first and last line of the following output:



ID Done Have ETA Up Down Ratio Status Name
3 1% 10.1 MB Unknown 0.0 0.0 0.57 Stopped Horrible Bosses {2011} DVDRIP. Jaybob
Sum: 10.1 MB 0.0 0.0

The output is from transmission-remote. I am trying to dump this all into a variable in a script and it isn't going particularly well. I am trying to use sed but cannot get the command to work. This is what I have so far:


TORRENTLIST=$(transmission-remote --auth user:password --list | sed -e '1d;$d;s/^ *//' | cut –only-delimited –delimiter= ” ” –fields=1)

This is supposed to be dynamic so there could be 1 or 100 things in this list. The next step of my script feeds into a loop doing different stuff basded on their status and Completeness (if you wanted to know - lol).

My failing is that I copied this sed command from somewhere and I can't remember where. I have googled my life away trying to understand sed but I'm just there yet.

Many thanks in advance for any advice!

Thanks

Chris

it does exactly what you want
1d deletes 1st line, $d deletes the last line, s/^ *// removes spaces at the beginning (^) of each line (substitutes any sequence of spaces with nothing).

test:

$ echo $'ID whatever\n stuff\n more stuff\nSum: 666'
ID whatever
stuff
more stuff
Sum: 666

$ echo $'ID whatever\n stuff\n more stuff\nSum: 666' | sed '1d; $d; s/^ *//'
stuff
more stuff

You are completely right. I found what it was by sticking -x on my script but it was staring me in the face. Where I had copied it from the website it had copied in a load of additional random characters, changed some characters - all sorts of stuff was going on.

Many thanks for your quick response and help!
