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

On CentOS machine, the oneliner bash that worked for me was:

if ssh  "stat  > /dev/null 2>&1"; then echo "file exists"; else echo "file doesnt exits"; fi

It needed I/O redirection (as the top answer) as well as quotes around the command to be run on remote.
