It works too:
Code:
sed -n '/ORGANISM/{n;N;N;N;s/\n/ /gp}'

readable format:
Code:
sed -n '/ORGANISM/ {
                                       n;N;N;N
                                       s/\n/ /gp        }'

thanks for your quick answer.

Still doesn't produce what I need. I have 725 records, in each record contein the match ORGANISM with 4 lines on each. I would like to have at the end 725 lines with this four lines in one

example:
if I use

Code:
grep -A 4 'ORGANISM'

I got :

Code:
  ORGANISM  Ventrifossa garmani
            Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi;
            Actinopterygii; Neopterygii; Teleostei; Euteleostei; Neoteleostei;
            Acanthomorpha; Paracanthopterygii; Gadiformes; Macrouridae;
            Macourinae; Ventrifossa.
  ORGANISM  Bathygadus antrodes
            Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi;
            Actinopterygii; Neopterygii; Teleostei; Euteleostei; Neoteleostei;
            Acanthomorpha; Paracanthopterygii; Gadiformes; Macrouridae;
            Bathygadinae; Bathygadus.

and what I need is this:
Code:
ORGANISM  Ventrifossa garmani Eukaryota; Metazoa; Chordata; Craniata Actinopterygii; Neopterygii; Teleostei Acanthomorpha; Paracanthopterygii; Gad Macourinae; Ventrifossa.
ORGANISM  Bathygadus antrodes Eukaryota; Metazoa; Chordata; Craniata Actinopterygii; Neopterygii; Teleostei Acanthomorpha; Paracanthopterygii; Gad Bathygadinae; Bathygadus.

Hello,

I tried this command and it worked fine.
My question is that how can we replace the N by a variable, to print for instance a big number of lines. It means if I want 100 lines after an expression, to not put N 100 time in the sed.

Code:
$ sed -n '/aaa/{n;N;N;s/[ \n]//g;s/;/; /g;p;}' ttt2
1
2
3
 
$ cat ttt2
0
aaa
1
2
3
4
5
6
7
8
9
10

Thx & Regs,
Rany.
