With one word is o.k., with more than 1 word is not ok !!!

Manuales — Fri, 23 Dec 2005 12:03:50 GMT

Hi..
i'm doing a script which is going to verify when a process is down.
All proceses are in a file called PROCESOS.txt, it was crated whit result of:
ps -fea > PROCESOS.txt

now, when a process is only 1 word there is no problem and this word is kept in a variable named "proceso" but when are more than 1 it can not to keep the words in the variable proceso , i'm attaching images about script and the run
where it says " el valor de fin es 11" you can see when "k vale 9" is not doing things (echo commands) progrramated in script.
My doubt is ,why can not all words in variable proceso ?

Thanks, Manuales.

I can't open your attachment so I'm guessing that you are assigning the lines of text from PROCESOS.txt to a variable and you're probably not using quotes, so you're only getting the first word of the line. Try using quotes.

Thanks Pete,i have alredy found the solution:

before:
"fin" variable cold be 10 or more than 10
....
....
fin=$(echo $proc | wc -w )
.....
.....
case $m in
[9-$fin])....
...... ;;
esac

After:
fin=$(echo $proc | wc -w | cut -c1)
fin2=$(echo $proc | wc -w | cut -c2)
....
....
case $m in
9 | $fin[0-$fin2])...
....
esac

That was the solution !!!
i was using other sintax with case comand ...

Thanks, Manuales.

Can you post your script here and not in the attachment. And what is the end result you are trying to do ?

Input: take in the command and all the arguments and save into a file.

Output: ??

you can try the "x" option to ps -efx
which shows all of the process arguments and options.
