Scrollback

Scrollback is the output you can revisit above the current terminal screen. Terminalis saves a bounded snapshot so a later app launch can restore what you were reading.

Restore output #

Switching terminals keeps their buffers alive. After an app restart, a terminal loads its saved output before displaying new shell output. A dim session restored separator distinguishes the old contents from the new session.

This restores text, not processes. A development server visible in restored output is not necessarily running now; check its status dot. The cache is saved periodically, so a hard crash can lose recent output. macOS cache cleanup can remove it entirely.

Clear output #

With the terminal focused, press Cmd+K to clear its view/scrollback and delete the saved scrollback snapshot. This does not delete shell command history, change the remembered directory, or stop the running program. New output can begin filling the screen immediately.

The terminal menu's Re-Initialize also clears output while replacing the shell. The settings-change reinitialization prompt preserves output instead. Running the shell's own clear command is not equivalent to deleting Terminalis's persisted cache.

Scrollback limit #

Open Settings → Terminal and change Scrollback (lines). The default is 10,000; the setting accepts 100 through 1,000,000 lines. Larger buffers use more memory and cache space across your terminals.

The setting is app-wide and applies to new or reinitialized terminal sessions; follow the Settings restart message. Increasing it cannot recover lines already discarded. Keep an explicit log file for output that must survive cache eviction, profile deletion, or clearing.
