Execute Bash script stored in a file over SSH

Question

Say I have the following Bash script stored in the file foo.sh:

#!/bin/bash
echo foo

Without having to scp the fi

Answer 1

In accepted answer I see:

I'd like to have it as a one liner. Could you make a small code example?

That should be it:

ssh root@MachineB 'bash -s -- uno' < local_script.sh

or better, with a here-in document

ssh root@MachineB 'bash -s -- uno' <<\EOF
> date
> echo $1
> EOF

uno

Answer 2

ssh root@MachineB 'bash -s' < local_script.sh

I got it from that thread: How to use SSH to run a shell script on a remote machine?

Answer 3

cat foo.sh | ssh HOSTNAME 

Now tested, though: handle with care! :)
(removed dash (see comments) and nearly everything :) )

Answer 4

You can use runoverssh:

sudo apt install runoverssh

runoverssh -s localscript.sh user host

-s runs a local script remotely

Answer 5

cat foo.sh | ssh -T root@remote will to the trick. The -T option suppresses a warning you would otherwise get because you're piping input from a file.
