Running part of bash script on a remote machine

Question

I need to run some commands locally and then some command on a remote machine all using a single local bash script.

For simplicity just say I want to do the following and execute it on my local desktop machine.

#!/bin/bash

#upload some files to a remote machine
cd /tmp
./upload-files.sh

#run commands on remote machine
ssh myuser:[email protected]
cd /tmp/uploads    <--- these commands don't run in the ssh connection
./process-uploads.sh
exit

#run command locally again.
cd -
echo 'complete!'

Any ideas of how to do this?

You can use here-doc with ssh command:

#!/bin/bash

#upload some files to a remote machine
cd /tmp
./upload-files.sh

#run commands on remote machine
ssh -t -t myuser:[email protected]<<EOF
cd /tmp/uploads
./process-uploads.sh
exit
EOF

#run command locally again.
cd -
echo 'complete!'

Do I need the double -t -t?

With single -t I got a warning Pseudo-terminal will not be allocated because stdin is not a terminal.

If you want to run only one command:

ssh myuser:[email protected] 'cd /tmp/uploads; ./process-uploads.sh'
