Customize silent running processes with frame animations and text in Linux Bash shells.
This Linux Bash command line utility can attach itself to any process by PID and run a custom animation of frames by string or array with the addition of prepended and appended text with the animation and the ability to change the speed of the animations by spreading the frames over seconds with the '-s' switch (e.g. -s 3, spreads over 3 seconds). This is great for silent processes, especially in sub shells or scripts. This tool works with any color and otherformatting that can be used with printf.
