| | Command History - Wikipedia, the free encyclopedia |
 | | Command history takes advantage of the fact the user may want to execute the same command many times, such as a developer frequently compiling and running a program, or else the new command may be a small modification of a previous one, hence necessitating little typing to modify it. |
 | | Command history is a common feature in command line interface, such as in operating system shells: Korn shell, Bash shell, etc... |
 | | Command history involves making previously made commands, usually up to some number of the last ones, easy to once again input to the command line. |
