ssh and chdir to my PWD on the local computer

[TJ Luoma]

I wanted to be able to ssh to another computer and immediately chdir
to the same directory that I was using locally.

I came up with _a_ solution, but I'm not sure if it's a good one, or
if there would be other ways to do this more easily/better, so I'm
sharing it here.

Since all of the computers are under my own control, I was able to
accomplish this by editing the ssh_config and sshd_config files to add
`SendEnv CWD` and `AcceptEnv CWD` respectively.

/etc/ssh/ssh_config:   SendEnv CWD

/etc/ssh/sshd_config: AcceptEnv CWD

I also added this to the end of my .zshrc file:

if [[ "$CWD" != "" ]]
then
    echo "changing to '$CWD'"
    cd "$CWD"
fi

Then I was able to use this by connecting to my remote computer like this:

        CWD=$PWD ssh remote.host.tld

The last part seems a little clunky, although I'm sure I could make a
function or something, but I wondered if anyone else has solved this a
different way, and if so, how… or does anyone have a suggestion how to
do this differently / better?

Thanks for your time

When I need to run some commands before an interactive SSH session, I
do it like this:

    ssh -t user@host "cd ${(q)PWD}; zsh -i"

It's quite flexible.

I used to pass variables to ssh by editing the configs this way; but
having multiple machines (some of which I don't have root on) made it
too clunky.

Now I usually do

    ssh -t host VAR=value ... zsh

You can save that as a shell alias; or edit ~/.ssh/config and define
RemoteCommand for the hosts you want.

I use this function:

   scd() {
     local term=
     case $# in
       (0)
         echo "usage: $0 <host> [<command> [<arguments>...]]"
         return 1
         ;;
       (1)
         term=-t
         ;;
     esac
     local host=$1
     shift
     ssh $term $host cd ${(q)PWD} '&& exec $SHELL' ${1+-c} ${(qj: :)*}
   }
