sed perhaps?

Shell Programming and Scripting

i am a total SED noob so i hope that someone can help ..

very simply, i have a file with text:

white1
1
white2
0
white3
0

i would like to have it piped to a file that looks like the following:

white1 1 
white2 0
white3 0

i have tried a couple of simple commands with no luck:

for example i want to see the entry with 1 to the right

sed -n /1/p file

gives this result:

white1
1
white2
white3

as i indicated, i am a noob but this should be easy .. any help would be appreciated and thanks

Hi.

If you have only one number following each colour:

$ sed "N; s/\n/ /" file1
white1 1
white2 0
white3 0

$ xargs -n2 < file1
white1 1
white2 0
white3 0

paste -d" " - - < file1
white1 1
white2 0
white3 0

in perl

perl -wnle '! /^\d+/ and printf "$_ " or  print $_ ;' infile.txt

;);):wink:

or perhaps more easier:-

perl -wnle '$.%2 and printf "$_ " or print;' infile.txt
