Those of you working in the CLI a lot - what are your favorite aliases that might be useful to others?

Some of mine:
- Better ls command: alias lsa='ls -lAFh'
- A command to drop/recreate/re-seed my Postgres DBs: alias dbnuke='bundle exec rake db:drop db:create db:migrate db:seed'

@niclake A git alias i've been using for a long time:

first-push = ! git push --set-upstream origin $(git rev-parse --abbrev-ref HEAD)

For pushing the branch the first time, when it would otherwise be rejected with an error of "The current branch xxx has no upstream branch."
