BASH: Getting the md5 hash of file on remote server

Question

Is there a way I could get the md5 hash of a file on a remote server?

I'm looking for a command like

md5 hlin117@server:/path/to/file.txt

Solution

AFAIK there is no remote md5.

The closest you can get is to execute the command on the remote server:

ssh hlin117@server md5sum /path/to/file.txt

Obviously, md5sum must be installed on the remote server.

Alternatively, get the file and do it locally:

scp hlin117@server:/path/to/file.txt .
md5sum file.txt
rm file.txt

Or, as @Cyrus pointed out:

ssh hlin117@server cat /path/to/file.txt | md5sum

Thanks! Your first solution worked. (PS: I wanted to get the md5 hash sum so I don't need to scp it locally.)

With a local md5sum: ssh hlin117@server cat /path/to/file.txt | md5sum
