Dear Sysgate

Thank you for your response.

A very old linux book, linux in easy steps explains one of the modes very well:


"... the vi editor has one of the most bizarre and seemingly non-user-friendly interfaces ever invented... The first, and most important thing to learn about vi is that it has two modes. When you are in input mode, everything you type goes to the screen, and into the file you are editing. (the only exceptions to this are the curson-movement commands and the exit from input mode command) When you are in command mode, nothing you type goes into the file you are editing.; rather it will be interpreted as a command to the editor to do something. Understanding this is the key to understanding vi

An example

1. Start a new file called "testfile"

vi testfile

2. Press "i" to enter input mode. Type some text and press ESC

hello this is vi |

3. You are in command mode. Press O and the cursor will return to the beginning of the line. Press "x" 5 times and on each stroke on eletter of the Ist word will be deleted.

4. Now press ":" A colon prompt will appear on the bottom line. You are now in command of every mode. Type "q!" and press RETURN. This will quit vi without saving and return to you to the shell prompt (This has been one of the greatest mysteries. I used to get stuck in the vi prompt and it seemed impossible to get out of the vi prompt unlesss I shut down and restarted the computer !

The author goes on to present some useful commands and colon commands:

i Insert before the character the cursor is on etc

Cursor Movement

G Go to the last line of the file etc

Miscellaneous Commands

J join the current line to the next one etc.

Getting out of vi

:wq write file, then quit etc


Other colon commands:

:sh Run a temporary shell (CNTL-D to return)

Is there anything like this in the man pages or elsewhere that LISTS and explains various command modes?


Thank You.
Thanks.

NAME
mmsclient_script - script file for mmsclient program SYNOPSIS
mmsclient_script DESCRIPTION
This man page describes the syntax of the script file that is driven by the mmsclient(1M) utility. This file contains a list of Media Man- agement Protocol (MMP) commands that are used to communicate with a Media Management server. The MMP and the commands in the script file are based, in part, on IEEE 1244, the Media Management System (MMS) standards. In the script file, each MMP command must start with one of the following symbols as the first character: # Comment character Indicates the following characters document the file or command. Any character following the # character on the same line is ignored. @ Async command Indicates that the command on the next line is sent in async mode. Any character following the @ character on the same line is ignored. The MMP command to be performed must start on the next line. Commands that are not preceded with the @ character are sent in sync mode, that is, the mmsclient command waits for a response before continuing to the next MMP command in the file. $ Sync point Forces the mmsclient command to wait for a response to a previous async command. For example, if the script contained an async com- mand such as: @task["Get volume Names"] ...a subsequent command: $Get volume Names ...stops the script until the volume names are retrieved. > Interactive MMP prompt Displays a prompt on the display device and pauses the script. To respond to the prompt, type the requested information, ending with the semicolon (;) character. The mmsclient utility then sends the information to the MMS server. To skip the MMP prompt, type the q character. % Pause the script The script stops until you press the Enter key. ! Execute a command The mmsclient utility issues a call to system(3C) to invoke a command. Whatever command follows ! is run in the shell in which mmsclient is run. For example: ! date See the shell commands in the example script below. EXAMPLES
Example 1 Example Script The following script, demo_example, demonstrates the special characters and some MMP commands. It is executed with default values when the command: # mmsclient -f demo _example ...is run. #mmsclient example script #Send show commands in sync mode show task["sync show command 1"] report[DM] reportmode[namevalue] number[1..2]; show task["sync show command 2"] report[LM LIBRARY] reportmode[namevalue] number[1..2]; #Pause the script and wait for someone to #press Enter to continue % #send show commands in async mode @ show task["async show command 1"] report[DRIVE] reportmode[namevalue] number[1..2]; @ show task["async show command 2"] report[CARTRIDGE VOLUME] reportmode[namevalue] number[1..2]; #set a sync point for the second async command, #to stop the script until the response is complete $async show command 2 #set a sync point for an unsent command and set #a sync pont for a command that has already received a response. #mmsclient does not stop for either one $sync show command 1 #Start interactive MMP prompt. #To continue, enter an MMP command or 'q' > #Register for a some events notify task["notify test3"] receive[tag["client connected"] object[CONNECTION] action["add"] match[streq(CONNECTION."Language" "MMP")]] receive[tag["client disconnected"] object[CONNECTION] action["delete"] match[streq(CONNECTION."Language" "MMP")]] receive[tag["DM connected"] object[CONNECTION] action["add"] match[streq(CONNECTION."Language" "DMP")]] receive[tag["DM disconnected"] object[CONNECTION] action["delete"] match[streq(CONNECTION."Language" "DMP")]] receive[tag["LM connected"] object[CONNECTION] action["add"] match[streq(CONNECTION."Language" "LMP")]] receive[tag["LM disconnected"] object[CONNECTION] action["delete"] match[streq(CONNECTION."Language" "LMP")]] ; #Pause the script #Connect another mmsclient to see some events #Press Enter key to continue % notify task["delete all CONNECTION events"] cancel[object[CONNECTION]]; #Pause the script and wait. #Connect another mmsclient to verify the events are cancelled. #Press Enter key to continue % #Execute some simple shell commands !echo Hello World !uname -a !hostname #Pause the script and wait. #Press Enter key to continue % #Send last command in async mode. #mmsclient does not exit until it receives the responses #for all pending commmands. @ show task["async show command 3"] report[APPLICATION] reportmode[namevalue]; @ show task["async show command 4"] report[AI] reportmode[namevalue]; ATTRIBUTES
