  Command History - Wikipedia, the free encyclopedia
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.
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.

History expansions introduce words from the history list into the input stream, making it easy to repeat commands, insert the arguments to a previous command into the current input line, or fix errors in previous commands quickly.
History expansions are introduced by the appearance of the history expansion character, which is `!' by default.
The `-s' option to the history builtin may be used to add commands to the end of the history list without actually executing them, so that they are available for subsequent recall.

Otherwise, the exit sta- tus of the command builtin is the exit status of command.
First and last may be specified as a string (to locate the last command beginning with that string) or as a number (an index into the history list, where a negative number is used as an offset from the cur- rent command number).
In the second form, command is re-executed after each instance of pat is replaced by rep. A useful alias to use with this is ``r=fc -s'', so that typing ``r cc'' runs the last command beginning with ``cc'' and typing ``r'' re-executes the last com- mand.

 ITworld.com - Using history and command line editing
You may use command line editing to edit the command that you are currently working on after you have typed it in, or you may recall a previous command and then edit it.
History is more than just the ability to recall previous commands; it lets you recall commands and edit them before they are executed.
History and command line editing behave very differently depending on whether you are using vi, emacs, or gmacs.

As part of a change to the Unified Command Plan, President Bush migrated space missions from the former USSPACECOM and subsequently nominated Admiral James Ellis to be commander of the new unified command, which would retain the U.S. Strategic Command name and would be headquartered at Offutt.
The new command was established in response to a dramatically changing security environment generated by emerging global and transregional threats.
The command's reorganization also allowed for a more centralized command and control of the nation's space-based assets and ensured nearly every military space asset was represented in the new USSTRATCOM, broadening the scope of personnel assigned to the command, to include more Army soldiers and Marines, in supporting the full spectrum of military operations.
