This is not a homework guys I was just trying to capture the output of a free command from 100 servers to an excel sheet. However, I want it in different columns instead of predefined format of free command.
I have acomplished it by redirecting ooutput to three different files using awk and pasting it to one file in tabular format and redirecting it which worked.
however, I thought it as a lengthy process to capture the outputs seperately and then pasting it That's why I asked this question hoping that some other trick will work.
Thanks!
My hunch is to first sort the list so it looks like this:
abc
def
ghi
100
200
300
Then--eg--you can use sed to combine groups of lines. Here is a start, based on the sorted list above: sed -n -e '1,3H' -e '3{g;s/^\n//;s/\n/ /gp}' filename
sed -n 'h;n; :a x;$!N;s/\n/ /;ta;p;x;p' infile > outfile
It needs an even number of input lines or it will reverse the order of the two output lines.
Or try
Code:
sed -n 'p;n' infile | paste -sd' ' > outfile
sed -n 'n;p' infile | paste -sd' ' >> outfile
sed -n 'p;n' prints every second line starting with line 1.
sed -n 'n;p' prints every second line starting with line 2.
paste -sd' ' converts multiple lines into a single line with a space as the deliminater.
