Scripts by Category

ISO/USB Burning

iso_dd.sh — Lists ISO files and writes to USB drives.

# ./iso_dd.sh /path/to/ISOs/  # Lists ISOs, then prompts for selection

Uses dd with 4MB block size. Double-check device paths to avoid data loss.

imgburn.sh — Minimal ISO burner.

# ./imgburn.sh ubuntu.iso /dev/sdX

DANGEROUS: Direct dd invocation without safety checks. Use only for trusted media.

System Maintenance

old_scripts/updater.sh — System update wrapper.

# ./old_scripts/updater.sh

Runs sudo apt update upgrade autoclean autoremove in a loop.

old_scripts/extbackup.sh — Full system backup to external USB.

# ./old_scripts/extbackup.sh

Archives ~ to /mnt/media/$USER/backupdr/arch_backup/. Clears browser caches before backup. Requires mounted external drive.

Plex Media Management

plex/plex_fileswitch.sh — Syncs local media to Plex server.

# ./plex/plex_fileswitch.sh /path/to/movie.mp4

Uses rsync over SSH. Has an unresolved merge conflict in current HEAD.

plex/aviconverter.sh — Batch video conversion.

# ./plex/aviconverter.sh

Converts *.avi to *.mp4 using VLC with H.264/MP4A encoding. Usage: ./aviconverter.sh /path/to/video/*.avi

plex/checkdate.py — File listing utility.

# ./plex/checkdate.py /mnt/Plex/Media/Movies

Simple Python script to count files in a Plex directory.

Networking

networking/deauth.sh — WiFi monitoring and deauthentication.

# ./networking/deauth.sh

Puts device in monitor mode, then enters interactive loop. deauthNet function sends 100 deauth packets to a MAC address (runs 30×). Requires: aircrack-ng suite and wireless interface (e.g., wlan0).

File Organization

file_organizer/organizer.sh — Auto-sorts files by extension.

# ./file_organizer/organizer.sh /path/to/files/

Moves old files (>30 days) to archive folders: ~/Archive/{Documents,Images,Scripts,etc}. Skips hidden files. Creates destination directories if missing. Note: Uses stat -c "%Y" (Linux) not stat -f (macOS). macOS users need adjustment.

User Administration

administrative/user_audit/permis_check.sh — System user audit.

# sudo ./administrative/user_audit/permis_check.sh

Checks for active vs. inactive accounts, logs last login times. Incomplete: Missing variable declarations (ACTIVE_USERS, INACTIVE_USERS arrays never initialized). Does not output full report.

Quick Utilities

old_scripts/argcnt.sh — Counts and displays arguments.

# ./old_scripts/argcnt.sh arg1 arg2 arg3
# Output: "there are 3 arguments" then lists each

old_scripts/save.sh — Quick web scraper.

# ./old_scripts/save.sh https://example.com

Extracts first image URL from page source, saves via wget. Relies on page HTML structure—fragile.

old_scripts/bgrotate.sh — GNOME wallpaper rotator.

# ./old_scripts/bgrotate.sh

Picks random image from ~/Pictures/Wallpapers and sets as GNOME background. Intended for cron: * * * * * /path/to/bgrotate.sh

old_scripts/fldrmkr.sh — Web dev folder creator.

# ./old_scripts/fldrmkr.sh

macOS-only: Creates project folder with index.html and resources/css/index.css. Linux users will fail at /Users/$USER/Dropbox/... paths.

old_scripts/installer.sh — Legacy system setup.

# ./old_scripts/installer.sh

Installs specific tools: Vundle.vim, GNOME helpers, Kismet, cursor pointer toggle. Reads from ~/Documents/packages/installfiles.txt for deb packages. Deprecated: Prefer package manager scripts for reproducibility.

Dotfiles

dotfiles/fish_config/tide_install.sh — Tide theme installer for Fish shell.

# ./dotfiles/fish_config/tide_install.sh

Installs Tide prompt theme v6 from GitHub releases.

Merge Conflicts & Incomplete Files

File	Issue
plex/plex_fileswitch.sh	Contains unresolved Git merge conflict markers (<<<<<<< HEAD)
iso_dd.sh	Incomplete logic—never actually calls burnISO function
networking/deauth.sh	Runs while true loop indefinitely; requires manual Ctrl+C
administrative/user_audit/permis_check.sh	Missing variable initialization; incomplete loop

---

Safety Notes

1. imgburn.sh and iso_dd.sh both use dd without safety checks. Always verify /dev/sdX is your target drive.
2. networking/deauth.sh can interfere with neighboring WiFi networks. Use responsibly.
3. file_organizer/organizer.sh moves files without confirmation—review the logic before running on critical data.
4. old_scripts/installer.sh assumes specific paths and dependencies; test on a VM first.

---

Cleanup Recommendations

• Remove old_scripts/ if these tools are no longer needed
• Fix or delete plex/plex_fileswitch.sh until merge conflict is resolved
• Archive administrative/user_audit/ logs older than 30 days
• Consider rewriting iso_dd.sh with explicit umask and blkid validation
