I used grep <command output> | cut -d ':' -f 3 | column -x >> $temp to write data in tabular format. But there seem to be huge difference in length of strings which causes the table to skew. I need to format these with equal spacing. How can I do that?
Edit: The file that the command runs on contains text as following:
total_STDIO_OPENS: 176400

I am grep'ing using grep -Ein 'total_stdio_read|total_posix_write|total_stdio_write|total_posix_read' $file | cut -d ':' -f 3 | column -x >> $temp
Desired output is:
2 0 0 184
2 0 0 184
765311 61423 6454323302 470948
598500 678403 6454288800 1810469
So what worked for me was mix of solutions.
<command output> | cut -d ' ' -f 2 | column -x | xargs -n4 printf '%-10d %-10d %-10d %-10d\n'
