diskutil list

# This will output a bunch of info about all of the disk drives connected to
# your Mac. Each entry will have a header in the form "/dev/diskX", where X is
# some number starting at 0. Now, insert your USB drive and run the command
# again. You should see a new entry. Make note of the name (ie, /dev/diskX).

If a project has to have multiple git repos (e.g. Bitbucket and Github) then it's better that they remain in sync.

Usually this would involve pushing each branch to each repo in turn, but actually Git allows pushing to multiple repos in one go.

If in doubt about what git is doing when you run these commands, just

# put this in your .bash_profile
pull_request() {
  to_branch=$1
  if [ -z $to_branch ]; then
    to_branch="master"
  fi
  
  # try the upstream branch if possible, otherwise origin will do
  upstream=$(git config --get remote.upstream.url)
  origin=$(git config --get remote.origin.url)
