butcher.sh (a.k.a. "The Butcher")

This tool is intended to modify your professor's awful video recordings to something slightly more bearable. To be more precise, the tool is capable of:

• Removing silent parts
• Apply audio filtering like pop and click removal, high- and low-pass filters
• Normalize volume in case the levels are off

Usage

From the releases page or directly from the main source, download the butcher.sh script and place it anywhere on your computer. Open a terminal in the same directory and you can start using it right away.

Upon first use, you might have to run the following command:

chmod +x ./butcher.sh

to make the file executable.

The tool can be operated in interactive or CLI mode. You can run interactive mode by typing

./butcher.sh -i

It will then start asking you questions about all necessary information.

In CLI mode, you just give all necessary parameters as options. Type ./butcher.sh --help to see a list of available options and their description. Example:

./butcher.sh \
	--install-deps \
	--create-outdir \
	--options removesilence,audiofilters \
	./data/ \
	./out/

Dependencies

butcher.sh has the following dependencies:

• ffmpeg
• ffpb
• python3
• pip3
• jumpcutter
• figlet

However, you do not need to install them manually, as the script will already do this for you automatically (simply answer y when prompted or --install-deps in CLI mode).

set-llvm-version.sh

Changing defaults versions for llvm programs is tedious and time-consuming. This little script aims to make the process lighning-fast, by searching for all installed llvm programs and configuring them using update-alternatives (so make sure that is installed)

Usage

As usual, before first use, you should execute chmod +x ./set-llvm-version.sh to make it executable.

You can set the default version of all llvm programs (including clang, llc etc.) using the following command:

./set-llvm-version.sh --all XX

where XX is the version number you want to set.

To set just a single program in the llvm family, use the --name <prog> <ver> option.

The script will try to automatically figure out where llvm is installed. If it fails to do so, you can provide a custom installation directory with the --install-dir option.

random.sh

Simple script to generate random md5 hashes of arbitrary length. Simply download the script and make it executable with chmod +x random.sh.

Invoke with

./random.sh <length>

If invoked with no arguments, default length is 8.
