Linux reset command

Linux Command大全

The Linux reset command is actually the same as the tset command, and its purpose is to set the terminal state. Generally speaking, this command will automatically determine the current terminal type from environment variables, command lines, or other configuration files. If the specified type is '?', the program will prompt the user to enter the terminal type.

Since this program will reset the terminal to its original state, it can also be used to reset the terminal when the system terminal enters some strange states due to the abnormal execution of the program. For example, if you accidentally use the cat command to enter the terminal with binary mode, the terminal may no longer respond to keyboard input or respond with some strange characters. In this case, you can use reset to restore the terminal to its original state.
