Python Extracting Archives: unzip & Safe Decompression
The `unzip` command decompresses ZIP files. Extracting directly into dedicated target folders using `-d <directory>` prevents "tarbombs" and "zip bombs" from scattering hundreds of loose files into your current working directory.
"Unpacking an archive without `-d` is like opening an overstuffed luggage bag in the middle of your living room: clothes scatter everywhere. Using `-d` unzips it directly into a designated closet."
Deep Dive: How It Works
Target Directory (-d): `unzip -q archive.zip -d /target/dir/` extracts all files into the specified directory (creating it if necessary).
Overwrite Modes: `-o` (overwrite existing files without prompting), `-n` (never overwrite existing files).
Testing Integrity (-t): `unzip -t archive.zip` verifies CRC checksums across all compressed files without extracting them to disk.
Syntax Blueprint
unzip archive.zip unzip -q -o archive.zip -d /opt/app/ # Quiet, overwrite, into /opt/app unzip -t archive.zip # Test integrity checksums
Always use -d to extract into an isolated target folder.
Core Rules to Remember
Common Beginner Traps & How to Fix Them
Extracting an untrusted zip archive without checking its internal path tree.Why it happens: Poorly structured archives may dump 5,000 files into your home directory.
How to fix: Run `unzip -l archive.zip` first, or always extract with `unzip archive.zip -d extracted_folder/`.

Extract a Zip File to Target Directory
- Create a zip `/tmp/ezip/test.zip` containing `sample.txt`.
- Extract it into `/tmp/ezip/dest/` using `unzip -q -o /tmp/ezip/test.zip -d /tmp/ezip/dest/`.
- Print extracted content and clean up.
