re: AWK question 1

Hey,


I am trying to do

who -u | nawk '{print $1, $6, $7}' >/tmp/myfile


I would like the output to be neatly formatted by spaces.My output now is all squished together. Can someone help please.

Try:
who -u|nawk '{print $1, " ", $6, " ", $7}'>/tmp/myfile

Bill.

To get a well aligned output (you can play on the %10s parameter):

who -u | nawk '{printf("%10s %10s %10s %\n",$1,$6,$7)}' >/tmp/myfile

Hope this helps!

My post had a typo (sorry). This one should work:

who -u | nawk '{printf("%10s %10s %10s \n",$1,$6,$7)}' >/tmp/myfile

#!/usr/bin/ksh

# who -u | nawk '{print $1, $6, $7}' >/tmp/myfile

who -u|while read LINE #reads the results of"who -u" line by line
do
# define variables
USER_ID=`echo $LINE|awk '{print $1}'`
TIME=`echo $LINE|awk '{print $6}'`
PID=`echo $LINE|awk '{print $7}'`

# determines the length of USER_ID and adds two tabs if less than 8
# \t is a tab
case ${#USER_ID} in
[1-7])
echo "$USER_ID\t\t$TIME\t\t$PID"
echo "$USER_ID\t\t$TIME\t\t$PID" >> /tmp/myfile.$$
;;
*)
echo "$USER_ID\t$TIME\t\t$PID"
echo "$USER_ID\t$TIME\t\t$PID" >> /tmp/myfile.$$
esac
done

echo "Results can be found in /tmp/myfile.$$"

looks like the printf is much neater!
I'll save that in my notes.
