Question dummy question on data process
I have a file which contains 6 columns.
But I only need the first 3 columns. So I need to remove the last 3 columns. I checked 'cut' but it seems not working.
So is there a command that could remove certain columns from a file? Smilie
Thanks a lot!!

That's what I would use:
Code:
awk '{printf("%s %s %s\n",$1,$2,$3)}'

nawk instead of awk under Solaris.

Cut does work too:

Code:
cut -d" " -f1-3
