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.
