Unzip Files Without Overwriting

Step 1 — Ask for the target directory

Before running anything, ask the user:

"Which directory should I extract archives from?"

Accept absolute or relative paths. Expand ~ to the full home directory path if provided.

Step 2 — Detect the OS and run the correct script

macOS / Linux — run the bash script directly:

bash /path/to/skill-test/unzip-files.sh "/the/target/directory"

Windows — run the CMD wrapper (do NOT use pwsh or powershell directly):

C:\path\to\skill-test\run.cmd "C:\the\target\directory"

IMPORTANT: On Windows always use run.cmd. Never invoke pwsh or powershell directly. run.cmd calls powershell.exe (Windows PowerShell 5.1) automatically.

Step 3 — Report results

Summarize what was extracted, renamed, and removed.

How the scripts work

• Accept a target directory as argument (defaults to . / current directory if omitted)
• Validate the directory exists and resolve it to an absolute path
• Search recursively through the directory and all subdirectories
• .zip / .tar.gz / .tgz: extracted into a new subfolder named after the archive
• .gz (single file): decompressed in-place (name.gz → name)
• If the output target already exists, the archive is renamed with _1, _2, etc. — nothing is overwritten
• Original archive files are deleted after successful extraction
