Decompressor

Decompressor is a Bash script designed to handle nested compressed files automatically. Given an initial compressed file (data.gz by default), the script decompresses it and continues extracting any subsequent compressed files generated in the process until no further compressed files remain. This is especially useful for dealing with multi-layered archives.

Features

• Recursive Extraction: Automatically decompresses nested files, handling multiple layers of compressed content.
• Signal Handling: Captures Ctrl+C to exit gracefully, displaying a custom exit message.
• Customizable Start File: The initial file to decompress can be modified by changing the first_file_name variable in the script.

Requirements

• 7z (p7zip) must be installed for this script to work, as it relies on this command-line tool for decompression.

Usage

To use Decompressor, simply execute the script. By default, it looks for a file named data.gz in the same directory. You can modify this file name by changing the first_file_name variable within the script.

./decompressor.sh

Example Output

[+] New decompressed file: file1.gz
[+] New decompressed file: file2.gz
[+] New decompressed file: file3.txt
...

How it works

• Initial Extraction: The script begins by decompressing the specified first_file_name (default: data.gz).
• Nested File Detection: After each decompression, the script checks for additional compressed files within the newly decompressed content.
• Recursive Loop: This process repeats until no further compressed files are detected, effectively “unwrapping” layers of compressed files.
• Signal Handling: If Ctrl+C is pressed, the ctrl_c function is triggered, which exits the script and displays an exit message.

Notes

• Warning: Only run this script on files you trust, as extracting unknown files may pose security risks.
• To customize the initial file, modify the first_file_name variable in the script.
