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
