# script to add gcloud instances to ssh config
#
# Usage: tpu_configssh.py <instance_name> <instance_name> ...
#
# A version of this exists in gcloud compute config-ssh but it doesn't work for TPU VMs
#
# Works by parsing the output of dryrun mode of gcloud compute ssh, example:
# $ gcloud alpha compute tpus tpu-vm ssh instance-name --dry-run
# /usr/bin/ssh -t -i /home/user/.ssh/google_compute_engine -o CheckHostIP=no -o HashKnownHosts=no -o HostKeyAlias=<alias> -o IdentitiesOnly=yes -o StrictHostKeyChecking=no -o UserKnownHostsFile=/home/user/.ssh/google_compute_known_hosts user@IP

This gist shows how to use rebase to change the Git history of a repo. Imagine you realise that the first commit to your repo should be different (maybe it's incomplete, includes something it shouldn't or simply could be cleaner). However, since then you and others have made many changes to the repo that you want to preserve. Here we show how to split the first commit into multiple and re-attach the remaining version history to these new commits.

Let's make a dummy git repo rebase-root and add two files to it. We commit them with the commit #1.
