Even though this question has probably been asked countless times in other communities, I still want to know: what tool do you think comes closest to ShareX? I'm particularly interested in features like image capture, video recording, GIF creation, and OCR reading all in one tool for Linux.
Personally I use ksnip. Pretty sure it doesn't do video though. It does do assorted image capture, OCR (if you have Tesseract installed), and supports uploading to imgur, FTP, and anything you can manage to do with a script.
There isn't really a perfect replacement for ShareX that I know of.
Your question would be much easier to answer if you explained what it is that this ShareX thing does that you want to do.
As it apparently doesn't exist for Linux, or else you wouldn't have asked, it seems safe to assume that most Linux users aren't familiar with it.
It's all in one open source capturing tool:
• Capture full-screen, active window, specific regions, and more.
• Record your screen with or without audio, and save as video or GIF.
• Upload images, text, or other types of files to over 80 supported destinations.
• Includes a colour picker, image editor, ruler, and more.
• Add text, arrows, shapes, and blur parts of your captures.
• Automate repetitive tasks with custom workflows and hotkeys.
Flameshot + Xsnip = ShareX and more
