Kill remote process via ssh
I have a process that I want to kill remotely. I tried
ssh remotehost "kill -9 $(ps -aux | grep foo | grep bar | awk '{print $2}')"
but this returns the error
kill: usage: kill [-s sigspec | -n signum | -sigspec] pid | jobspec ... or kill -l [sigspec]
However if I run the command within the quotation marks
kill -9 $(ps -aux | grep foo | grep bar | awk '{print $2}')
on the remote host it works fine. Am I missing something here?

The shell on the local host is running the ‘grep’s before it is being sent to the remote host. You need to escape your command. Eg
ssh remotehost "kill -9 $(ps -aux | grep foo | grep bar | awk '{print $2}')"

The $(..) command substitution would fail as the $ is expanded by the local shell even before it is passed to the stdin of the ssh command. You either need to escape it or use here-strings.
With escaping,
ssh remotehost "kill -9 $(ps -aux | grep foo | grep bar | awk '{print $2}')"
or with here-doc
ssh remotehost <<'EOF'
kill -9 $(ps -aux | grep foo | grep bar | awk '{print $2}')
EOF
