A collection of handy shell scripts for automating tasks on macOS and Linux.
This script removes GPS location metadata from image files to protect privacy.
Ensure you have exiftool installed:
sh
brew install exiftool # macOS (Homebrew)
sudo apt install libimage-exiftool-perl # Ubuntu/Debian
Run the script with a file or directory as an argument: sh ./remove_gps_exif.sh path/to/photo.jpg
To process all images in a folder: sh ./remove_gps_exif.sh path/to/folder
Removes GPS metadata (-gps:all=) Works on single files or entire directories Overwrites original files to prevent data leaks

Ensure you have ImageMagick installed: sh brew install imagemagick # macOS (Homebrew) sudo apt install imagemagick # Ubuntu/Debian
Run the script with a file or directory as an argument
Compress and resize a single image to 800x600 with 80% quality: sh ./compress_resize_images.sh image.jpg 800x600 80
Process all images in a folder with default quality (85%): sh ./compress_resize_images.sh /path/to/folder 1024x768
Supports JPG, JPEG, and PNG formats Allows setting max width and height (800x600 format) Adjustable compression quality (default: 85%) Processes single files or entire directories
This script converts FLAC audio files to MP3 format using ffmpeg.
Ensure you have ffmpeg installed: sh brew install ffmpeg # macOS (Homebrew) sudo apt install ffmpeg # Ubuntu/Debian
Run the script with a file or directory as an argument
Convert a single FLAC file to MP3 (default 320kbps): sh ./flac_to_mp3.sh song.flac
Convert all FLAC files in a directory at 192kbps: sh ./flac_to_mp3.sh /path/to/folder 192k
Supports batch conversion for directories Retains metadata from the original FLAC file Allows customizable bitrate (default: 320kbps) Outputs MP3 files in the same directory as the source FLAC files
This is a simple shell script designed for macOS to monitor available disk space on your main volume (/) and provide a visual alert if it falls below a customizable threshold.
- Clone this repository or download
disk_space_checker.shdirectly: bash git clone https://github.com/yourusername/your-repo.git cd your-repo
Run the following command in your Terminal to make the script executable: bash chmod +x disk_space_checker.sh
Optional: Move to a Bin Directory. For easy access, move it to a directory in your $PATH, like /usr/local/bin: bash mv disk_space_checker.sh /usr/local/bin/disk_space_checker

Run the Script: Execute the script from its location: bash Wrap Copy ./disk_space_checker.sh Or, if you moved it to a bin directory: bash Wrap Copy disk_space_checker
When disk space is sufficient: text Disk space looks good! 45 GB available out of 250 GB. Usage: [========= ] 18%
When disk space is low: text WARNING: Low disk space! 8 GB available out of 250 GB. Consider freeing up some space. Usage: [= ] 3%
Open the script in a text editor (e.g., nano disk_space_checker.sh).
Adjust the THRESHOLD variable (default is 10 GB): bash THRESHOLD=20 # Change to 20 GB
- Color-Coded Alerts: Green for sufficient space, red and yellow for low space warnings.
- Customizable Threshold: Set your own low-space limit by editing the THRESHOLD variable.
- Visual Progress Bar: Displays a simple bar showing the percentage of used disk space.
- Error Handling: Checks for valid disk space data and exits gracefully if retrieval fails.
- Lightweight: No dependencies beyond standard macOS tools (df, bash).
