comment Setting up OpenSSH to use rhosts?
Steps 2-5 can be replaced with simply running ssh-copy-id user@remote-host on the local machine that has both the public and private keys. The remote host will ask for user's password this time only so a) user must have a password, and b) remote-host must be configured to allow password logins. see the man page for ssh-copy-id(1) for more details.

comment Renaming a bunch of files with date modified timestamp at the end of the filename?
@StéphaneChazelas: programs can easily find out if they're being piped to by checking where stdin is a tty or not, so it's not unheard of for programs to behave differently if data is being piped into them. I can't recall ever seeing a version of date that did that though.
