hi

what you are doing is assigning a set of values to variable by this command.

w | more generates some output which contains a lot of text and you are assigning this to the variable process. and when you print process, these values get printed.

what are u trying. if you could give some more info, i will be able to help.

correct me if i am wrong.

Hi

Since the number of parameters in a line is variable you will not do it.

try something silly like

w|tail -n +3|cut -c1-29,50-256

Try:
# process=$(w|more)
# echo "$process"

Best regards...

what purpose does the pipe to more in the command substituion serve?

DUMP=$(w)

should suffice
