Version: v0.1

Summary: A quick script a threw together to allow Mac or Linux users to create and flash splash screens for their HTC Android phones.

Requirements:

• imagemagick
• nbimg
• fastboot

Code:

#!/bin/bash

##Written by Blake Johnson
##Website: http://www.blakeanthonyjohnson.com/
##Script requires ImageMagick and nbimg to be installed and located in $PATH.

v0.1: Initial Release

Version: v0.2

Summary: Ever wanted to mass rename a bunch of files into a specific pattern based on their original filenames? Yeah, there are other utilities out there, but this is a simple solution based on my FilenameSanitizer script which locates filenames in a given directory with a specific pattern, and then renames them based on that pattern. As of the current version, it’s set to unify numeric .jpg images. For example, “5466.Jpeg” would become “005466.JPG”.

Requirements:

• find
• sed
• wc
• whoami

Changes:
v0.2: Initial Release
v0.1: Prototype

Credits: Special thanks to Kevin Warns for creating a prototype for me to start off with.

Summary: This script was designed to help ease the migration of data from a Mac or Linux PC to a FAT32 flash drive, which in turn would be compatible with Windows. It does this by attempting to find any questionable characters in any of the file names, and replacing them with hyphens ‘-‘. It also removes leading and trailing spaces, along with trailing periods.

Requirements:

• find
• sed
• tac (coreutils)

Code:

#!/bin/bash

LOG="${HOME}/.FilenameSanitizer.log"
TMPLOG="/tmp/FilenameSanitizer-`whoami`"

##Write Date & Time to Log File

exit 0

Changes:
v0.6: Simplified the search command. Added some more questionable characters. Added ability to set parameters at the command line. Displays usage line upon error.
v0.5: Name changed to “Filename Sanitizer”. Simplified the replacement of illegal characters. Parses the results in reverse order. Added check for duplicate names. Commented code a bit.
v0.4: Search results are now written to a file instead of variable, fixes bug with trailing spaces, removes trailing periods, removes leading and trailing spaces, counts and shows success rate.
v0.3: Name changed to Filename Cleanser. Added more questionable characters to search for.
v0.2: Errors are logged, exit status of each rename command, and some other revisions.
v0.1: Initial release.

Bugs / Unimplemented Features:

• File names with repeating periods _may_ end up disappearing off the face of the planet. (I don’t know why, or how.)

Summary: This script will check to see if a web server is functioning properly by checking the output of a specific location. If this output is wrong, or unavailable, a message will be emailed. Additionally, if the server returns output which the script was not expecting, it has the ability to run a custom restore command and hopefully get the server functioning again.

Requirements:

• mail
• curl

Code:

#!/bin/bash
##Set Default Options
CHECKFOR="" ##This is the what the script expects to find in the result.
TIMEOUT="10" ##Max amount of time to wait for a connection.
MAXTIME="30" ##Max time to spend trying to load page.

##Do not edit anything below this comment!
