who to arrange dataset 2

[valle70]

Hi
"who -m" gives me following output
root
user1

"who -m|awk '{printf("%s",$1)}'" gives me following oupput
rootuser1

I would like make a awk script that orders the lines show below seperated by a _

root_user1

who do I do this ?

Regards

Try something like this:
who -m|awk '{printf "%s",(NR>1?"_":"")$1}'

Hope This Helps, PH.

there are sure better ways to do this,
but the answer to your question is:

who -m|awk '{printf("%s%s",(xx++) ? "_" : "",$1);}'

dont forget the closing ';' after ')' for syntax purists
be sure you are using the new-awk

bonjour PHV, en effet 'NR' est bien plus efficace que 'xx'
je corrige:

who -m|awk '{printf("%s%s",(NR >1) ? "_" : "",$1);}'
