run a shell script which reference another script on ssh
Clash Royale CLAN TAG#URR8PPP
I have two bash scripts main.sh and a util.sh, and I reference utils.sh in the main.sh by using . util.sh. Now I want to run main.sh via ssh. Obviously, this won't work:
ssh user@host "bash /dev/stdin < main.sh"
Because remote shell cannot find util.sh. So how should I do this, without copying util.sh to remote machine ?

To run a remote scriptssh user@host main.shwould be enough actually. Why can't you just copyutil.shover as well?

Maybeutils.shis a common module and reused by many scripts

You still can deploy it tohosttogether withmain.sh. Or put it onto a shared/network drive somewhere. Or havemain.shcheck whether it is available locally and download it from somewhere if not.

Even though I think deploying util.sh to host would be the better/more stable solution, you could do something like putting this on top of main.sh
#!/bin/bash
U=$(mktemp)
cat > "$U"
. "$U"
rm -f "$U"
# rest of script
and then run
ssh user@host main.sh < util.sh
To be more fail-safe you may require some extra coding in main.sh to handle issues with the temp file being unwritable/undeletable, no input passed on stdinetc.

This is ugly, but should work:
ssh user@host bash < <(sed 's/. util.sh/ r util.sh; d' main.sh)
That will embed the contents of the util script into the main script, and then pipe the script to the bash process running on the remote host.
Note that I've removed the double quotes: the process substitution needs to run on your local machine where both files reside.
