Ubuntu ClipGrab

Refer: https://www.how2shout.com/linux/install-clipgrab-on-ubuntu-20-04-lts-download-youtube-videos/

Step 1: If we want to also convert the Youtube and other online videos on your Linux system then we need FFmpeg library installed on our system. For that use the command:

sudo apt install ffmpeg

Goto: https://clipgrab.org/

Step 2: Open Clipgrab official website, here is the link. Click on the “Show all download options” and then download “Binaries for 64-bit Linux“.

Step 3: When the download of the file gets completed, right-click on the Clipgrab Youtube downloader App image and select properties.

Make Clipgrab AppImage executable Ubuntu 20.04 min

Step 4: To run the Clipgrab, first, we need to make it executable. For that, mark the checkbox given in front of “Allow executing file as program“. option.

Allow permission to run Clipgrab min

Step 6: Now, double click on the ClipGrab file, this will open this Youtube downloader. After that select the Downloads tab and paste the URL of the online video you want to download on your Linux system and then click on the “Grab this Clip!”.

Create Cligrab Desktop and Application launcher shortcut (optional)

By default, the file will be in your Downloads folder because we got it from the browser. But there are chances of deleting it accidentally, thus let’s move it to some secure place.

ImageMagic – Swapping Colors in PNG or JPG Files

Installing ImageMagic
$ sudo apt-get install imagemagick imagemagick-doc

The new Yellow Colors are this:

Selected state: #FFCB66
Hover state: #FCB614

The interesting thing about ImageMagic is the convert actually has the target color first and the color to replace second, as a parameter.

In order to change the colors for the location_and_decks, do the following:

Use the PNG files because they are lossless and convert them.

This is for changing blue to yellow for the selected items

for f in *.png; do
convert ./"$f" -fuzz 0% -fill "#FFCB66" -opaque "#0D932C" ../../locations_and_decks/"$f"
done

Unfortunately, the hovers for blue, were the same color as the border, so we took the selected and converted them to hovers; however, the names needed to be changed too.

for f in *.png; do
convert ./"$f" -fuzz 0% -fill "#FCB614" -opaque "#0D932C" ../../locations_and_decks/hover/"$f"
done

After getting all of the PNG's into the same folder you can use the following to convert all of the PNG files into JPG files.

for f in *.png; do
convert ./"$f" -background white -flatten -alpha off ../locations_and_decks/"${f%.png}.jpg"
done

Remote Execution Commands

Here are some of the tools I have used in the pass to do various things. If I have to use something today then that would be SSH and Ansible for any mass operations

For all small jobs I generally go with SSH safe and secure.
Here are some of the examples of how you can put SSH to use. Make sure you setup credential keys for ease.

www.cyberciti.biz/faq/unix-linux-execute-command-using-ssh

www.cyberciti.biz/faq/linux-unix-osx-bsd-ssh-run-command-on-remote-machine-server

Following is the tool that allows you execute commands on multiple hosts. This is Python based.

Ansible:

On Windows machine I used PowerShell. I find powershell too complicated and cryptic
