- The HISTORY command is used to control the 2.04 console handler history features.
- This command allows you to review, load, save, clear, and change the size of the
- history buffer. In addition, the command allows you to re-execute portions of the
- history buffer without using the cursor keys.
-
- The history command can be used to display the current history buffer just
- by using the command
-
- history
-
- To see the last N entries in the history buffer, you also the number, eg
- history 10 will show you the last 10 entries. (You can also say
- history LINES 10).
-
- To see N entries in the history buffer, starting with entry X, you would specify
- both numbers, eg
-
- history 8 start 20
-
- which will display 20 history lines starting with history entry # 8.
- (you can also say HISTORY LINES 8 START 20)
-
- On the left margin of the history listing is the command histry number. To supress
- those numbers, use the NONUM keyword. (this is often useful when redirecting the
- output of the history cmmand into a file or a pipe.
-
- The LOAD keyword allows you to preload the history buffer, up to the limits of the
- current size of the history buffer.
-
- SAVE saves the current history buffer to a file. NOTE: partial saves are possible,
- following the same rules as partial listings of the history buffer.
-
- The CLEAR keyword erases the contents of the history buffer. It may be used by
- itself, or with one of the other keywords.
-
- The SIZE keyword allows you to change the size of the history buffer of the
- current console-handler. You can change the size in 1K increments. The initial
- history buffer size is 2K.
-
- The RUN keyword allows you to run one or more commands in the history buffer.
-
- history run 5
-
- will run the last 5 commands.
-
- history run 3 start 5
-
- will run 3 commands, starting with the 5th entry in the history buffer.
-
- a useful alias is
-
- alias ! history lines 1 run start
-
- which kind of gives that Unix csh effect.
-
- When the RUN option is specified, if no START is specified, START defaults
- to the last command. If no LINES is specified, LINES defaults to one.
-
-
- The SHOW option is there as a default; it can be combined with other options,
- however.
