NAME

       ssh-diff - diff a file over SSH

SYNOPSIS

       ssh-diff [OPTIONS] FILE [user@]hostname[:FILE]

DESCRIPTION

       diff a file over SSH

       There is an extra roundtrip to the remote system
       to check for the existence of the file to be diffed.
       So if you are not using SSH Keys
       you may get prompted twice for a password.

       Use "CHECK_REMOTE_FILE_EXISTS=NO ssh-diff" to disable that behavior

DIFF_OPTIONS

       All options your local diff command supports ( except '-r' ).
       See 'man diff' and 'diff --help' for more information.

SSH_OPTIONS

       -4     Use IPv4 only

       -6     Use IPv6 only

       -p port
              Port to connect to on the remote host.
              This can be specified on a per-host basis in the configuration file.

ENVIRONMENT

       CHECK_REMOTE_FILE_EXISTS    NO|YES    remote file checking
