Krellan's Scripts

Updated 1/23/2003

These are some handy Perl and Expect scripts that I have made recently. They are for use on Linux, but should be flexible enough to easily be ported elsewhere. I have found them useful.

 Here are my scripts! Download. (very small file)

Here are 3 scripts that each operate on a given directory. They process all the files and directories beneath that directory, recursively.

• extsize.pl — File Extension Size
  This will find all files in the given directory and group them by extension. It will then tell you how many total files and total bytes are taken by each extension. Handy for finding what is taking up so much disk space!

• dupedetect.pl — File Duplicate Detector
  This will find all duplicate files in the given directory, and also find files that have a length of zero (mostly useless files that can be safely deleted). All files are properly compared using a byte-for-byte comparison, so it will catch duplicates even if they have different filenames.

• mp3wav2ogg.pl — MP3-and-WAV to OGG Converter
  This will find all MP3 and WAV sound files in the given directory, and convert them into the increasingly popular OGG sound format. Not only will this save disk space, it will also save money! All MP3 and WAV files will be backed up, so you can go back if you do not like the conversion. MP3 files are converted to WAV as a temporary step, before finally converting to OGG.

And here are 3 more scripts that form a "suite":

• makeipwebpage.pl — Make IP Web Page
  This creates a HTML page containing details of your current Internet connection. This is useful if you have a dynamic IP address that often changes (such as dialup, DHCP, or PPPoE). The other 2 scripts here can be used to upload that HTML page to a webhosting provider, so you can access it from a remote location and learn where your machine is.

• scpupload.exp — Upload File to SSH Server
  This is an Expect script that executes the scp command and automatically enters your password when asked. It also answers "yes" to the "Are you sure you want to connect" warning that sometimes appears. This makes it much easier to automate the use of scp. This script uploads a file to a host and username that are preset in the script. That way, they do not need to be repeatedly entered on the command line.

• uploadip.pl — Upload IP
  This uses the above 2 scripts to make a webpage containing your machine's current IP address and upload it to your website! This script can be set up to run automatically when your PPP connection is established. That way, you will always be able to find your machine online!

Extensive documentation is provided with each script. Please read the comments at the beginning of each script.

These scripts are free to use for personal use, and to redistribute under the GPL. Please do not redistribute them in any other way without first asking me.

If you have any questions please let me know!
