echo $length "RND Character String Was placed in Clipboard, have fun :)"
            

Usage: ./randomstring.sh *NumberOfCharacters*

What it does: outputs a random string of characters defined by a positional argument to your clipboard.

Note: the xsel portion can be removed if you want the string to be dumped in the terminal.

#!/bin/bash

filenum="$(find -maxdepth 2 -type f | wc -l)";
finalfilenum="$((filenum-1))";
printf "%s" "$finalfilenum" " Files found.";
printf "\nPlease use the Shift+Tab keys to select all files.";
sleep 4; clear;
fzf="$(fzf -m -q / | tr '\n' ' ')" && mv $fzf "$(pwd)";
cd "$(pwd)";
            

Usage: Put the script in the directory containing the sub-directories you want to extract the files from,

then run ./directorydumper_v2.sh

What it does: for every folder, it goes 1 folder depth in to fetch files & dump them into the script directory.

Note: fuzzy finder (fzf) is a dependency. This script will not work if filenames have spaces. (I might fix it)

Usage: ./worldbackup_v4.sh

What it does: it backups a folder every day, that's fundamentally it.

Note: This is the script that I was talking about in the Minecraft Server page.

I tested the logic & everything is fine.
