Thanks by the answers, but specifically this is what I want
1.- first I obtain the list of guests active.
pipe cp q n| split /,/ | specs w1 1 | locate /CMP/ | > GUESTS LISTS A
Note: "CMP" is my pattern for guests in production mode in this partition.
For example: CMPWAPE1, CMPWSPE1, CMPDBPE1
My lists is
CMPWAPE1
CMPWSPE1
CMPDBPE1
2.- I am going to send this command to each guests linux of this list
cp send CMPWAPE1 start-stop.sh
3.- When this script finalize I need to erase this guets of the file "GUESTS
LISTS A" AND count the elements, to know if file is empty.
4.- if file is empty then I finish to the process and sent a message
"All the guets were process"
5.- If file isn't empty take the next guest name in file and return to step
2.
I do not know I can realise this loop with a pipe ?
Thanks to all by your help
