check if file exists on remote host with ssh

Question

I would like to check if a certain file exists on the remote host. I tried this:

$ if [ ssh user@localhost -p 19999 -e /home/user/Dropbox/path/Research_and_Devel         


        

Answer 1

ssh -q $HOST [[ -f $FILE_PATH ]] && echo "File exists"

The above will run the echo command on the machine you're running the ssh command from. To get the remote server to run the command:

ssh -q $HOST "[[ ! -f $FILE_PATH ]] && touch $FILE_PATH"
