How to check if a file exists on a server with bash

Question

Checking if a file exists on my computer is easy. But how about checking if this file exist on my server?

If my file is:

host@server:/path/to/my/file.txt

What do I need to do to check if it exists?

You might want to look at the manual page for `ssh`. – Some programmer dude Dec 01 '11 at 16:36 — Some programmer dude, Dec 01 '11 at 16:36

How about this?

ssh user@host 'if [ -f /path/to/my/file.txt ]; then echo yes; else echo no; fi'

Something like this could help -

ping -c 1 ipaddress && ssh user@host 'test -e /path/and/filename && echo exists'
