Quick Command Line

Sometimes in X-window, the mouse and keyboard do not work due to a program error. In this case, don't worry, because in Linux, it is almost not as vicious as in win 9X, you only need to press CTRL + ALT + backspace to return to the character interface.

CTRL + A: move the cursor to the beginning of the row.

CTRL + E: move the cursor to the end of the row.

CTRL + L: Clear the terminal. This shortcut works the same as typing clear in the command line.

CTRL + D: log out and close from the shell prompt. You do not have to enter exit when using this shortcut key.

Tab: command line auto-completion.

CTRL + ALT + Delete: shutdown and reboot. This method is used only when the shutdown fails.

CTRL + C exits from the insert mode to the command mode, equivalent to ESC.

CTRL + u scroll up half screen

CTRL + D scroll down the half screen

Liunx does not have the rename concept. It is used to move MV folder1 folder2 to change the folder name MV test1 Test2 1. Move the file 2. Rename the file sudo mvsourcename. The desname permission is insufficient to escalate the permission to move the file.

Find cp rm can be used to operate files and folders. If-R is specified, it is used to operate folders.
