Linux bash script with the command w

[Trini Alvarado]

Hello,
I try to make a script to count the points jcpu was obtained from the command w.
For that I have this code
This is the bash code

/ bin / bash
w | awk-f utils.awk

And utils.awk:

N> 2 {
    i = N - 1
    name[i] = $1
    jcpu[i] = $6
}

I want to use name [i], and jcpu [i] outside. Awk, but I can not. I must get out of. Awk, perhaps with a print, but despite several attempts, I have not managed to find a solution. If you guys have a solution for this then please let me know I am the interested one here. Thanks in advance.

Hello,
I think i know the answer for your question, but already a good shot in the man you show that "w-h" will have the figures.

w-h | awk '(print $ 6)'

Then just count the time forgetting to convert everything into seconds and it should pass. I have no idea about the necessary function but I do so very dirty, a regexp that looks for the letter s in the result or the letter m and if it is in hours. All in a file awk if you really want.

Hello,
I think I have a similar kind of a problem and I am trying a similar code for doing the same. I must count the points jcpu per user, or usefulness of the name [i]. Then I must use name [i], jcpu [i] in my script to make additions, subtractions with. I would like to use name [i] and jcpu [i] in my. Sh and not put them in a file share.

Hello,
See if the following script helps you

/ bin / bash

x=0

'w' | while true
do
	read ln # Reads one ln
	if [ "$ ln" = "" ] # If the ln is empty
	then
		exit # We leave the loop
	else
		set -- $ ln # Break the ln parameters $ 1, $ 2, etc..
		name[x]=$1
		jcpu[x]=$6
		let x=$ x+1 # Increment x
	fi
done

Hello,
Actually we see your complete script (with displays after the loop, etc.)? Otherwise it is rather one-dimensional arrays as variables, to display the contents of a box, it must give its index.

echo ${name[0]} # Print the contents of the first cell of the table name 
with the first term recovery of the first line of control w ...

I hope this will help you and if you have any more problem regarding this topic then you can post here and we will try to solve your problems.
