Shell Programming and Scripting

Hello

i have to connect to 11 servers to check the process size on every server.
how to that with shell scripting using ssh

regards

What do you mean by process size ? However, you can do that easily with "expect" scripting language, have a look at the global net or local forum resources.

what OS, what process?

for instance on linux (>2.6.9 kernel) you cat look in /proc/<pid>/status for the VmSize line i.e.

$ grep VmSize /proc/1508/status
VmSize: 4404 kB

and via ssh it would be

ssh -l <username> <host> grep VmSize /proc/1508/status

I guess one can just issue

top

command on SSH to check all info.

hello

here is the command i am using to get the process size
top | grep SS |awk '{print $6}'| cut -c 1-4

i need to run this command on 11 different servers to grep the process size from these servers

and show it to me
regards

Let's exclude grep and cut:

top | awk '/SS/{print int($6)}'

for a start, the top command will fail unless you tell it you want to run it in batch mode, as sshd will not provide a valid $TERM variable.

apart form that something along the lines of :

for serv in host1 host2 host3
do
echo 
echo $serv
ssh $serv top -n 1 -b |grep SS |awk '{print $6}'| cut -c 1-4
done

should suffice, once you've ensured that the user running the script has passwordless keys setup.

the parameters to top are
-n 1 run 1 iteration and quit
-b run in batch mode, don't look for a terminal

hello

for serv in s11s s15r s25n
do
echo
echo $serv
ssh $serv top -n 1 -b |grep SS |awk '{print $6}'| cut -c 1-4
done

it works but here is the output

s11s

how to get only the server name and the value
to be like this
s11s 3844
