How bracketed paste wraps pasted bytes, how line editors use the markers, where trust ends, and how terminal programs enable, parse, disable, and test it.
A recovery and prevention guide for broken terminal state: blind reset commands, stty inspection, TTY targeting, job control, exact restoration, and traps.
A systems-level guide to POSIX terminal input processing, canonical and noncanonical reads, echo, signals, control characters, job control, and restoration.
tmux 3.0 shipped in late 2019 with changes from its normal development process — the major version bump was not a promise of semantic-versioning upheaval.
Interactive Bash editing is a library-driven state machine: keymaps, completion hooks, history, and terminal escapes all meet inside GNU Readline.
PTYs and a persistent server process explain how tmux and screen survive a dropped SSH connection, not just several shells in one window.
Use Haiku Terminal, Bash profiles and native filesystem tools safely, write portable scripts, and separate POSIX habits from Linux assumptions.
After accidentally catting a binary file, the terminal shows strange characters or wrong colors — the shell is fine, the terminal's display state is what broke.
Terminal and shell are separate programs linked by a kernel pty: one renders characters and handles input, the other interprets commands.
Full-screen terminal apps like htop and vim redraw the screen selectively and read keystrokes one at a time. This is the library layer that makes it possible.
TUI apps render clipped over SSH, or the terminal doesn't rewrap after resizing — the remote shell has a stale idea of the terminal's actual dimensions.
A practical set of real, working defaults commands to unlock hidden macOS settings, plus how to find and safely revert any customization yourself.
