Storing all the PID's in a variable.
Hi,

Code:
ps -ef|awk '{print $2}'

i want to store the result of the above command in a variable.
I never worked with arrays in shell scripting.
i tried the below code:
Code:
set a=`ps -ef|awk '{print $2}'`

But
Code:
echo $a

returns null.
I want to store the content in a variable and retrieve it line by line.
Please help me.
Thanks

Code:
#!/bin/ksh
set -A arr `ps -ef|awk '{printf("%d ", $2)}'`
i=0
while [ $i -lt ${#arr[*]}
do
    echo ${arr[i]}
    i=$(( $i +  1))
done

See Korn Shell Arrays - Assigning and Accessing Values - Part I
for other ways to do this
