An easy way to take a screenshot and share it

scrottaa.sh

#!/bin/sh                                                                       
# This script is made by Tomi Leppänen aka Tomin (http://tomin.site/)

# This script takes a screenshot from the part of screen that you can
# select by mouse and then it saves the screenshot to your Dropbox
# folder (location set by DIRECTORY variable) and then pastes a shared
# link to clipboard.

# It is recommended to add this as a hotkey to your DE/WM or compositor.
# It works on Wayland sessions as well, if you change the screenshot tool
# to fit your desktop and use XWayland for xclip. If you know any command
# line program that can manipulate clipboard on Wayland without XWayland,
# please tell me.

# The name of this script comes from command line tool called scrot. If the
# word scrot was turned into a verb by Finnish language rules, it would be
# scrotata.

# Configuration:
# Date format
DATE=$(date +%Y-%m-%d-%H-%M-%S)

# Directory to save images, change to whatever you want
DIRECTORY="$HOME/Dropbox/Photos/Scrot"

# Clipboard to use, values: 'clipboard' for keyboard, 
#        and 'primary' for mouse-middle-click
#        or 'both' for both of them
CLIPBOARD='primary'

# Screenshot tool, if you know other useful tools, feel free to email me
COMMAND='scrot -s'
#COMMAND='gnome-screenshot -a -f'

# Dropbox command, this may be different on some distributions
DROPBOX='dropbox'
#DROPBOX='dropbox-cli'

# Check dependencies
