Is there a terminal emulator (like GNOME terminal) for linux/unix out there, which allows for highlighting a single word always (such as "highlight the word FAIL in red")? Or maybe is there a plugin for the GNOME terminal (if such a thing like "plugins for the gnome-terminal" exists).
The solution should highlight the word regardless of what application is being run inside the terminal, i.e. running
cat test.txt should highlight the word as well as
Any help is greatly appreciated by my bleary-eyed eyes.
