Shortening ssh commands in ksh 2

[pdtak]

Is there a way to shorten these commands? because this script asks for a password 3 times

scp -p /usr/local/bin/${script_name} ${servername$iy]}://usr/local/bin/
ssh ${servernames[$iy]} /usr/local/bin/${script_name}
ssh ${servernames[$iy]} rm -f /usr/local/bin/${script_name}

Basically, I'm creating a script within a script, pushing it out to a server, execute it, and then removing it.

Thanks in advance.

Hi

Use "public key authentication".

man ssh-keygen

Hope This Helps, PH.

Whilst I totally agree with feherke and PHVabout using public key authentication you can get round the copy - run - delete cycle by running

ssh ${servername[$iy]} < /usr/local/bin/${scriptname}

YOu'll get an error message which looks like

Pseudo-terminal will not be allocated because stdin is not a terminal.

this can be suppressed with

ssh ${servername[$iy]} < /usr/local/bin/${scriptname} 2>/dev/null

but you'll lose any other error messages

Use the -t option.

For some reason the -t option didn't seem to work for me. From my AIX system

And I need to read the man pages more - nice one PHV
