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

In addition to the answers above, there's the shorthand way to do it:

ssh -q $HOST [[ -f $FILE_PATH ]] && echo "File exists" || echo "File does not exist";

-q is quiet mode, it will suppress warnings and messages.

As @Mat mentioned, one advantage of testing like this is that you can easily swap out the -f for any test operator you like: -nt, -d, -s etc...
