Print even/ odd-numbered lines to new column I have a file with X number of lines in a single column and I want to print every even/odd-numbered line to a new column, is this possible in linux or `vim` editor? For example: Input file: RESOLUTION: 1.70 UNIT: MONOMERIC RESOLUTION: 1.80 UNIT: DIMERIC RESOLUTION: 2.50 UNIT: TRIMERIC RESOLUTION: 2.20 UNIT: TETRAMERIC Output file, which I need: RESOLUTION: 1.70 UNIT: MONOMERIC RESOLUTION: 1.80 UNIT: DIMERIC RESOLUTION: 2.50 UNIT: TRIMERIC RESOLUTION: 2.20 UNIT: TETRAMERIC

Assuming data is on file z1, then

paste -sd "\t\
" z1

will produce:

RESOLUTION: 1.70 UNIT: MONOMERIC
RESOLUTION: 1.80 UNIT: DIMERIC
RESOLUTION: 2.50 UNIT: TRIMERIC
RESOLUTION: 2.20 UNIT: TETRAMERIC

On a system like:

OS, ker|rel, machine: Linux, 3.16.0-7-amd64, x86_64
Distribution : Debian 8.11 (jessie)
bash GNU bash 4.3.30
paste (GNU coreutils) 8.23

Best wishes ... cheers, drl
