Assuming you end up with something like the following, after the loop

Code:

currpids_71="dell/server/serevr dell/server/apache dell/server/weblogic"

Now, it is time to split it by the space.

Code:

$ printf "%s\n" $currpids_71
dell/server/serevr
dell/server/apache
dell/server/weblogic

or time to use each individual result

Code:

$ for s in ${currpids_71}; do echo "do something with $s"; done
do something with dell/server/serevr
do something with dell/server/apache
do something with dell/server/weblogic
