The Ubuntu Community has these Forums and AskUbuntu for support.
If you want to give decent answers and really help all the users (even the beginners), you should probably provide images and even files describing what you're talking about.
But, snapping a screenshot, editing it, uploading it to an image hoster are all time-consuming tasks.
In this tutorial I will talk about how to install simple programs that will help you building your tutorials. This is NOT only for building your tutorials or answers, but also for sharing images and text quickly to everyone across the web.
I am working under Ubuntu 13.04 but this tutorial will also guide you on how to add these actions on keyboard shortcuts, in case you use some other environment. The right click shortcuts actions are only available on systems that run Unity.
How your setup will look like at the end of this tutorial:
The first 4 options on the dropdown menu will start Shutter which will immediately prompt you to select part of the screen. The first 2 of them will just take a simple screenshot while the last 2 will edit the image first with Shutter's editor. After you hit the 'Save' button on Shutter's editor then the image is uploaded to imgur.com. The word 'Delete' means that the image will be automatically removed from your hard drive once the image is successfully uploaded to imgur.com. The direct link to the image is pasted to your clipboard (and thus available anytime via Ctrl+V). If you don't delete your image, it will stay at ~/Pictures/ folder.
As for the 'Paste Online' option, it pastes your clipboard contents at paste.ubuntu.com and updates your clipboard with the corresponding direct link to paste.ubuntu.com.
Mention that this tutorial was built using the above setup.
So, first of all, install what you will need:
libnotify-bin: For displaying notifications through bash scripts
sudo apt-get install libnotify-bin xclip curl shutter pastebinit
xclip: For clipboard operations
curl: For imgur.com uploading
shutter: For screenshot capturing
pastebinit: For pasting to paste.ubuntu.com your text
Please after the installation of all the appropriate packages, run Shutter at least once to let it initialize/update its plugins.
If you work with Unity (if you work with Unity but you prefer keyboard shortcuts please go to the next section):
If you work with unity the best thing that you could do so as to have easy access to these actions is to create right click menu on a desktop launcher on the unity sidebar.
First of all, here is my custom gnome-terminal.desktop file:
Notice that adding these shortcuts to the gnome-terminal desktop file is NOT your only option. You may add these actions to any desktop file visible at your Unity sidebar.
Please save the above file as gnome-terminal.desktop and replace the string /home/alex with the corresponding user directory of yours (there are 5 occurrences) (e.g. /home/bongdacity). Move that file to /usr/share/applications/.
This requires root privileges. You can move the file either by terminal or by nautilus run by root. Place gnome-terminal.desktop to your home directory, open the terminal (Ctrl+Alt+T) and give
Fill in your password.
sudo mv gnome-terminal.desktop /usr/share/applications/
A more user friendly approach is running in a terminal
and then manually moving gnome-terminal.desktop to /usr/share/applications/. Please be very careful when you run nautilus with root privileges, a drag and drop can destroy your system if you are not careful.
If you don't work with Unity or you prefer using keyboard shortcuts:
If you don't work with Unity the best thing to do in order to have access to these actions is to setup keyboard shortcuts that will launch each one of these actions.
Almost every system has a way to setup your own keyboard shortcuts. For example, in Ubuntu this is under System Settings -> Keyboard -> Shortcuts -> Custom Shortcuts. There you can setup your own custom keyboard shortcuts. You can choose whatever shortcuts you like for each actions, but I would go with Ctrl+Shift+1 till 5. These are the commands that should be executed each time:
Take screenshot: /home/alex/Documents/Scripts/screenshot.sh js
Take screenshot (Delete): /home/alex/Documents/Scripts/screenshot.sh sd
Take screenshot (Edit): /home/alex/Documents/Scripts/screenshot.sh se
Take screenshot (Edit&Delete): /home/alex/Documents/Scripts/screenshot.sh sed
Please on the above commands replace the word alex with your own username.
Wherever you work, continue reading:
Now, it is the time to create the directory that will contain the scripts that will be executed for the above actions.
First of all, create the directory ~/Documents/Scripts/
Inside this directory, place the following files and give them the corresponding names
screenshot.sh -> http://paste.ubuntu.com/6003831/
imgur.sh -> http://paste.ubuntu.com/6003767/
pastebin.sh -> http://paste.ubuntu.com/6003783/
screenshot.sh: It launches shutter using the appropriate command line arguments. Also, it edits shutter's configuration files to satisfy the Open with Build-in Editor option of Shutter or not, which doesn't have a command line option. Also, it calls imgur.sh for uploading the picture, xclip for saving the link to your clipboard. It removes the local picture if needed.
imgur.sh: A script that uses curl to upload a picture to imgur.com. It takes as an argument a local picture and returns an imgur.com link.
pastebin.sh: Reads your input from the clipboard, it pastes it to (ubuntu.)pastebin.com and then updates your clipboard with the remote link. These are done solely with the help of xlip and pastebinit.
DO NOT forget to give the above scripts the executable bit (select the above 3 files in nautilus -> right click -> properties -> permissions tab -> Click on the 'Allow executing file as program' twice so as to show the tick mark) so as to be executed through the unity or keyboard shortcuts that you have set up.
Now you should be good to go
