exit_curses - Linux


Overview

exit_curses is a command used to restore the terminal settings to their original state after exiting a curses application. Curses is a library that allows programs to control the terminal, such as handling cursor movement, screen formatting, and color manipulation. By default, curses initializes the terminal settings when a program starts and resets them when the program exits. However, sometimes it’s necessary to manually restore the terminal settings, especially if the program crashes or terminates abnormally.

Syntax

exit_curses

Options/Flags

This command does not take any options or flags.

Examples

Example 1: Restoring Terminal Settings

./my_curses_program
# Do some curses operations
exit_curses

In this example, exit_curses is called after the curses application (my_curses_program) terminates, ensuring that the terminal settings are restored.

Common Issues

Issue: Terminal settings are not restored after exiting a curses application.

Solution: Make sure to explicitly call exit_curses before exiting the program.

Integration

exit_curses is typically used as the last command in a curses program to ensure that the terminal settings are properly restored. It can be integrated into scripts or command chains where curses-based operations are performed.
