If you've made some changes, need to stop what you're doing, and not commit, you probably want to use git's stash feature, which saves your changes and restores you to a clean copy of HEAD.

Here's how to do it:

 git stash save

...saves your local changes.

 git stash apply stash@{0}

OSX lacks the usbutils package. Sometimes you feel compelled to do hardware development in OSX, and it's nice to know if a device is enumerating properly.

To pull this off, run

 system_profiler SPUSBDataType

It may be helpful to alias this command to lsusb.

You can either make a script containing the above command or add

itdaniher

#!/usr/bin/env python

# Script for automatic backup of files to a fileserver using rsync.
# Directories to backup and details about the remote fileserver and
# exclude patterns must be  entered in the backup script itself.
# See 'User Configurable Parameters' below.
#
# Backup consists of three functions controlled by commandline arguments:
#
# /etc/backup sync
