history

Past events. A history feature in an application keeps track of user commands or retrieved items so that they can be quickly reused or reviewed. Web browsers maintain a list of downloaded pages in the current session so that they can be quickly retrieved. See Doskey.



DOSkey

An external DOS/Windows command that is used to display command history and create command macros (command shorthand).

DISPLAY COMMAND HISTORY
Run DOSkey with the number of commands to store, such as 200 in this example. Press F7 to display and Esc to close the history window.

        doskey /listsize = 200


CREATE AND USE COMMAND MACROS
The following example copies all the files in the current folder to the \BACKUP folder:

 macro     doskey bk = copy *.* \backup
 enter     bk
 executes  copy *.* \backup


To accept input, add "$1" as follows:

 macro     doskey bk = copy *.$1 \backup
 enter     bk gif
 executes  copy *.gif \backup


To view all the macros, enter:

       doskey /macros


SAVE THE MACROS
Macros last only for the current session. To use them again, save them in a batch file with the following command. Be sure to edit the file and add a doskey prefix to each line.

   doskey /macros > name_of_file.bat
