Better OS X Screenshots

screenshots.sh

# This will capture a screenshot, put it in your Public Dropbox folder,
# reveal it in Finder and copy a sharable URL to the clipboard. E.g.
# https://dl.dropboxusercontent.com/u/21267/shots/shot_2014-05-19_12-30-48.png

# Uncomment options below for things like opening in Preview,
# copying a Markdown/HTML image tag etc.

# Replace with your Dropbox user ID.
#
# Share something from your Public folder to find it.
# It's the number following /u/ in the URL.
dropboxuser=21267

# The folder inside your public folder you want screenshots to go to.
foldername=shots

# The filename for each screenshot. Includes date and time to maintain order.
filename=shot_`date '+%Y-%m-%d_%H-%M-%S'`.png

# Makes the containing directory if it doesn't exist.
path=~/Dropbox/Public/$foldername/
mkdir -p $path

# Takes the screenshot
#
# The `-i` sets interactive mode so you can select a region.
# Hit space to change to window selection mode.
#
# The `-o`  removes the window shadow from window selections.
# If you dig that, remove it.
#
# Change `-o -i` to `-m` for full screen screenshots instead,
# `-m` forces a multi-monitor setup to only capture the main monitor.
screencapture -o -i $path$filename

# Reveal in Finder
open --reveal $path$filename

# Open in Preview
# open -a 'Preview' $path$filename

# Build Dropbox public URL
#
# It will 404 until the file has finished uploading
publicurl=https://dl.dropboxusercontent.com/u/$dropboxuser/$foldername/$filename

# Copy URL to clipboard
printf $publicurl | pbcopy

# Copy Markdown image tag instead
# printf "![]($publicurl)" | pbcopy

# Copy HTML image tag instead
# printf "<img src="$publicurl" alt="" />" | pbcopy

# Open the URL in your default browser
# open $publicurl
