BASH alias running a script on another server

Question

This is either rather simple or impossible, however I can't seem to get a go with it. I'm trying to run a script located on a remote server and I have the following alias in my .bashrc:

alias fin='sh [email protected]:~/scripts/finder.sh'

I have set up SSH key authentication to that host, however I am getting the following error:

sh: 0: Can't [email protected]:~/scripts/finder.sh

Can someone please help, thanks :)

As an aside, classic sh does not support tilde expansion.

You cannot refer to a remote script as if it were a file name. You can use ssh but the syntax is slightly different.

ssh [email protected] scripts/finder.sh

As an aside, functions are often better than aliases.

fin () {
    ssh [email protected] scripts/finder.sh "$@"
}

The "$@" is for passing arguments. If the script takes no parameters, it can be omitted.

alias fin='ssh [email protected] /home/username/scripts/finder.sh'

you need to make sure finder.sh has execute permissions and runs locally on host.co.uk as user username

The remote shell will run from the remote user's home directory; hard-coding the full path is redundant and involves some speculation here.

For me on mac in bash shell it was resolving to /Users/username/scripts/finder.sh

Charles Duffy Over a year ago

@sdayal, it bases that on a lookup on the actual user's home directory, so it'll be appropriate for the system at hand. /home/username is convention for traditional unix-family operating systems, so it's presumably such a system that the OP is SSHing to.
