This post is to let people know that the Brother HL-2270DW printer can be installed and works under linux. I am currently using the printer in wifi mode printing to it from Ubuntu 13.04.

Here is the link to the installation instructions http://chadchenault.blogspot.com/2012/05/brother-hl-2270dw-printer-driver.html.

Remove Directories Using BASH Find Command

This post is to help me remember how to use the BASH find command to search and remove directories on my linux server. I currently am running an rsync backup command and storing the backups on the server. Each backup is stored as a folder as a date and time. For example '2013-1016-1400' would be a backup that occurred on October 16, 2013 at 1400 hours (2 pm).

List of Commands with Explanation

list only directories
  ls -d */

Search examples

! = do not find
example: ! -name "2013*" # do not find file name beginning with "2013"

Find year 2013, months 5-8, day 31, but not time 22**
 find . -maxdepth 1 -name "2013-0[578][3][01]-*" ! -name "*-22??"


Find year 2013, months 5-8, day 31, but not time 22**, and then delete directory
