Execute Commands on Multiple UNIX Servers

[unixscm]

Hi all,

I have 6 unix servers, i want to execute same command on the 6 unix servers.

I want a script which i will run from one machine to start and stop the remote services.

manual process
ssh ipaddress
cd /usr/scripts
ls -l

I want to automate this process thru script, i created the key gen to by pass the passowrd step.

i want in the script(test.sh)
like
ssh ipaddress
cd /usr/scripts
$1

where i want to pass the $1 from command prompt.

test.sh ls-l or test.sh df -k

i tried to write the script, i have problem in simulating the ENTER key press and append the next command after ssh ipaddress.

can you please help.

Thanks.

Perhaps expect could help you:

If you enclose the commands to run over ssh in double quotes like this it should do the trick.

ssh ipaddress "
        cd /usr/scripts
        $1
"

However, note that if you pass ls -l, then only the ls part will be in $1, and the -l will be in $2. Maybe you would prefer to use $@, which includes all parameters supplied on the command-line.
