AIX vi 命令
vi editing mode The vi editing mode has two typing modes. The modes are: Input mode. When you enter a command, the vi editor is in input mode. Control mode. Press the Esc key to enter control mode. Most control commands accept an optional repeat Count parameter prior to the command. When in vi mode on most systems, canonical processing is initially enabled. The command is echoed again if one or more of the following are true: The speed is 1200 baud or greater. The command contains any control characters. Less than one second has elapsed since the prompt was printed. The Esc character terminates canonical processing for the remainder of the command, and you can then modify the command line. This scheme has the advantages of canonical processing with the type-ahead echoing of raw mode. If the viraw option is also set, canonical processing is always disabled. This mode is implicit for systems that do not support two alternate end-of-line delimiters and might be helpful for certain terminals. Available vi edit commands are grouped into categories. The categories are as follows: Input edit commands Motion edit commands Search edit commands Text modification edit commands Miscellaneous edit commands
