Linux – How to select text in BASH terminal using the keyboard without mouse

Perhaps this works (source)

You can use GNU screen's copy and paste commands.

Quick tutorial:

1. Open screen: screen (or screen myprog my args here)
2. Run your program, producing output you want copied
3. Enter copy mode: ^A [
4. Move your cursor to the start point
5. Hit enter
6. Move your cursor to the end point
7. Hit enter
8. Paste: ^A ]

Screen is much more powerful than that (I use it to tab several virtual terminals without the need for a special terminal emulator, and also so that I don't loose my sessions when X crashes or something). To get out of screen, simply end your shell session, or type ^A ^.
