How to run a set of commands through ssh

vickylife · 11-13-2008, 07:15 AM

I need to run a set of commands on a remote machine using ssh. it should also collect output and return status of each command. Can someone help me how to do this?

Not a problem.

Something like

Code:

ssh user@remote 'command; command2; command3' > remote-output

You'll end up with a file 'remote-output' with the output from the commands.

This is homework....

Hmmm. Yeah, you may well be right. Looks like my homework detector has run out of juju.

Good job I didn't answer all of the question, really.

Thanks ilikejam. However my commands are related. That is i should be running command 2 only when command one is successful.

What commands are you supposed to be running?

in bash, you can just say 'set -e; command1; command2; command3;'
it will stop on a bad return code and return it to where you are calling it from.

i have to add few package in client machine in solaris. Before that i have to check if these packages also exist in server. So before installing on client first i will execute these three commands on server remotely(using ssh)
pkginfo SUNWabc
pkginfo SUNWpgr
pkginfo SUNWxyz

So say if the first package itself is not installed, i wont look for others and directly quit with an error message

Adjusting ilikejam's code to match new requirement:

Code:

ssh user@remote 'command && command2 && command3' > remote-output
