How to run a script file remotely using SSH

Question

I want to run a script remotely. But the system doesn't recognize the path. It complains that "no such file or directory". Am I using it right?

ssh kev@server1 `./test/foo.sh`

Answer 1

You can do:

ssh user@host 'bash -s' < /path/script.sh

Answer 2

Backticks will run the command on the local shell and put the results on the command line. What you're saying is 'execute ./test/foo.sh and then pass the output as if I'd typed it on the commandline here'.

Try the following command, and make sure that thats the path from your home directory on the remote computer to your script.

ssh kev@server1 './test/foo.sh'

Also, the script has to be on the remote computer. What this does is essentially log you into the remote computer with the listed command as your shell. You can't run a local script on a remote computer like this (unless theres some fun trick I don't know).

Answer 3

If you want to execute a local script remotely without saving that script remotely you can do it like this:

cat local_script.sh | ssh user@remotehost 'bash -'

It works like a charm for me.

I do that even from Windows to Linux given that you have MSYS installed on your Windows computer.

Answer 4

I don't know if it's possible to run it just like that.

I usually first copy it with scp and then log in to run it.

scp foo.sh user@host:~
ssh user@host
./foo.sh
