I want the selected lines of file to be print in output file side by side separated by space. Here what I have did so far,
for file in SAC*
do
awk 'FNR==2 {print $4}' $file >>exp
awk 'FNR==3 {print $4}' $file >>exp
awk 'FNR==4 {print $4}' $file >>exp
awk 'FNR==5 {print $4}' $file >>exp
awk 'FNR==7 {print $4}' $file >>exp
awk 'FNR==8 {print $4}' $file >>exp
awk 'FNR==24 {print $0}' $file >>exp
done

My output is
XV
AMPY

BHZ

Great; so look at your other post:

...where you were told to use CODE tags. And I'd recommend you do a quick Google search for using sed to join all lines together, or re-write your script to assign each awk to its own variable, and print them all at once, instead of appending everything to one line.
