Bash scripts

This repo contains some bash script that I have developed during the years. They don't do anything really important, but they help me automatize some of the things I do and I would be sad if they were somehow lost.

All of them are located in the scripts folder and can be run just by calling them in a POSIX terminal such as ./scriptname or sh scriptname.

Some of them will need additional programs installed in your machine, while others will accept parameters. Check the description here below to understand what they need and how they work.

Scripts

Binaural

Produces a binaural noise in your headphones (needed!). Binaural tones are proven to help in certain circumstances, such as sleep, focus, or stimulating creativity.

This script requires sox in order to work.

Use:

• binaural will play a binaural tone with default settings
• binaural -h shows help and default settings
• binaural [mode] [frequency] [harmonics] will play a binaural tone with the specified settings. Refer to the help for more information on the parameters

Makevideo

Produces a GIF and a .mp4 video coded in x264 from a folder full of images in .png format. All the images must be named in the format 0000000.png, 0000001.png, etc.

Use:

• makevideo will make a video from all the images in the frames subfolder
• makevideo [path] will make a video from all the images in the provided path
• makevideo [path] [output_video] [output_gif] will make a video and a gif from all the images in the provided path, with the provided names

Noise

Makes a mixture of white and pink noise to have some background sound.

This script requires sox in order to work.

Use:

• noise will play noise on a loop

Rainbow

Gives a little color to your terminal. Pipe any command into it or call a command with it to have a rainbow effect on the output.

Use:

• command | rainbow will print the output of the command with a rainbow effect

Randomfile

Fills a file with random ASCII characters.

Use:

• randomfile -h show script help and default values
• randomfile [path] [cols] [rows] will fill the file at the provided path with random ASCII characters. The file will be cols columns wide and rows long.
  • if cols is not provided, it will be set to 80
  • if rows is not provided, it will be set to 40

Uncommitted

Loops over all the subfolders of the current working directory and shows which of them contains uncommitted changes.

This script requires git in order to work.

Use:

• uncommitted -h shows help and default settings
• uncommitted -s or uncommitted --show-clean will show also the folders that don't have uncommitted changes. By default, only the folders with uncommitted changes are shown.
• uncommitted -u or uncommitted --show-uninitialized will show also the folders that are not git repositories. By default, only the folders that are git repositories are shown.
• uncommitted -a or uncommitted --auto-commit will auto commit and push all the uncommitted changes. By default, this option is not active.
  • all the uncommitted data will be pushed into a new branch called auto-commit-<timestamp>
• The parameters can be combined together

Updateall

Updates the system using the apt package manager.

This script requires apt in order to work (provided by Debian, Ubuntu, and other Debian-based distros)
