Run a local script on a remote server

cautionSSHalle

Caution: This command changes the system. Understand what it does before you run it.

Adjust the values, the command updates live
user@server
ssh webuser@server.example.com 'bash -s' < ./check.sh

Passes the local script file as standard input to a Bash on the server, which executes it line by line. No file is left behind on the server. Arguments can be appended after bash -s, for example 'bash -s' -- arg1.

Note: The risk depends entirely on the script. Interactive commands do not work this way because standard input is already in use.
