Of course you?d lose the ability to run multiple commands, redirect
I/O, etc. when using your proposed flag.

This was English, not German, BTW.

You would lose the ability to redirect I/O in an immediate way, but you 
would always be able to run a shell command like "/bin/sh"
"-c"
"any-command | tee cmd.log | process-further" which would regain the 
ability to do everything that a shell can do.


The problem from my original message, the ability to pass an arbitrary 
shell script to a remote host, would become trivial.


Best,

Yuri

For some values of English, perhaps.

Yes, but

	ssh -z remhost sh -c "something"

is exactly identical to

	ssh remhost "something"
