  Sorting files into folders based on exif date using python Code | (0)

  I like to sort my pictures based on the date they were taken. It can get pretty laborious to do so by "hand." Here is a little script I whipped together in about 30 minutes to make my life just a bit easier. Ain't it grand being able to simplify your life through programming! Caveat Emptor:  This is by no means a finished product, but merely a rough draft. # exif_sort[January 2012] / martin gehrke [martin AT teamgehrke.com] # sorts jpg/jpegs into date folders based on exif data from PIL import Image from PIL.ExifTags import TAGS import sys, os, glob def format_dateTime(UNFORMATTED): DATE, TIME = ...

  PXE to installed OS Code, SysAdmin | (0)

  Sometimes you unintentionally PXE boot while you would like to just let the local OS boot. This can happen if you have the boot order mixed up in BIOS or you hit a stray key during POST. Either way here is a helpful little entry to have in your PXE menu. label harddisk localboot 0x80 append SLX=0x80 0x80 - first partition of first HDD 0x81 - second partition of first HDD 0x00 - first floppy drive

  Bash, aliases, and command line arguements Code, SysAdmin | (0)

  I was recently doing some work with gzip'd files. It got kind of repetitive to keep typing gunzip file head file gzip file I know there is a zcat but I don't want to have to type zcat file | head everytime. You can create aliases in your .bashrc file. These are quick shortcut commands. The following does not work alias zhead='zcat $1 | head' #does NOT work In order for this to work you have to create a function in your .bashrc and call it from the alias. function zh(){ zcat $1 | head } alias zhead='zh'

  Find Code, SysAdmin | (0)

  Yanked from http://www.cyberciti.biz/faq/howto-finding-files-by-date/ -mtime +60 means you are looking for a file modified 60 days ago. -mtime -60 means less than 60 days. -mtime 60 If you skip + or - it means exactly 60 days.

  Editing fstab on a read only filesystem Code, SysAdmin | (0)

  Had an ubuntu build come up with a bad entry in /etc/fstab that was stalling the boot. I was able to get into a maintenance shell but / was mounted read only. Luckily I am not the only person to have had such an issue. mount -o rw,remount /

  10 Quick Tips Code | (0)

  I would not agree that these are usage habits, or even unix specific. But they are nifty. Make directory trees in a single swipe. Change the path; do not move the archive. Combine your commands with control operators. Quote variables with caution. Use escape sequences to manage long input. Group your commands together in a list. Use xargs outside of find . Know when grep should do the counting -- and when it should step aside. Match certain fields in output, not just lines. Stop piping cats. http://www.ibm.com/developerworks/aix/library/au-badunixhabits.html?ca=lnxw01GoodUnixHabits
