So rsync runs some checksums in the course of deciding what to transfer (i.e. what blocks within a file). But is there any reason to trust the file you end up with on the receive side any more than you would for a normal network transfer? Should I run checksums after rsync finishes to verify the data? Is rerunning rsync with the pre-check (i.e. --checksum option) turned on an accepted way to accomplish this?
We have a shared account on our system, which has login shell tcsh. I prefer bash and would like to have it run bash when I ssh in from my personal account but leave tcsh for anyone else using the account. I know I could set something up reflecting on the IP I ssh in from, but is there any (kludgy or non-kludgy) way to do this based on the user who ran ssh? Or a way to run ssh to get it to give me an interactive bash session?
