Basics

In this section, I will introduce the basics of the TUI of tracexec.

By default, the TUI comes with two panes: the Events pane and the Terminal pane.

The Terminal pane is focused upon launch but you can configure tracexec to focus the Events pane with a configuration file.

Terminal Pane

If you launch the TUI to trace a shell, you can type commands in the Terminal pane and tracexec will show the exec events in the Events pane.

If you launch the TUI to trace a program, you can interact with it in the Terminal pane.

Use Ctrl+U shortcut to enter scrollback mode, in which you can view the history of the terminal pane. Use ↑/↓/PgUp/PgDn/Home/End to navigate through the scroll buffer. Use Ctrl+U shortcut again to exit the scrollback mode.

Events Pane

Switch to the Events pane by shortcut Ctrl+S.

  • Use ↑/↓ to scroll up/down the events list.
  • Use PgUp/PgDn/Ctrl+↑/Ctrl+↓ to scroll faster.
  • Use Home/End to jump to the start and the end of the list.
  • Use ←/→ to scroll left/right in the events list.
  • Use Ctrl+←/Ctrl+→ to scroll faster.
  • Use Shift+Home/Shift+End to jump to the left end and the right end of the view.

To locate events by their text, use Ctrl+F. See Search for matching rules and result navigation.

How to Exit Vim Tracexec

When the Events pane is focused, press Q to exit.

You can switch to the Events pane by shortcut Ctrl+S if the Terminal pane is focused.

If there are still tracees running in the terminal pane, tracexec will wait for them after the TUI is closed. Press Ctrl+C to terminate them.

Layout

When the Events pane is focused,

  • Press Alt+L to change between vertical and horizontal layout.
  • Hold G/S to grow/shrink the Events pane.
