  • This Document Explains How to Copy Ondemand5 Data to Your Hard Drive
    Copying Your Repair DVD Data To Your Hard Drive Introduction This document explains how to copy OnDemand5 Repair data to your hard drive, and how to configure your OnDemand software appropriately. The document is intended for your network professional as a practical guide for implementing Mitchell1’s quarterly updates. The document provides two methods; one using the Xcopy command in a DOS window, and the other using standard Windows Copy and Paste functionality. Preparing your System You will need 8 Gigabytes of free space per DVD to be copied onto a hard drive. Be sure you have the necessary space before beginning this procedure. Turn off screen savers, power down options or any other program that may interfere with this process. IMPORTANT NOTICE – USE AT YOUR OWN RISK: This information is provided as a courtesy to assist those who desire to copy their DVD disks to their hard drive. Minimal technical assistance is available for this procedure. It is not recommended due to the high probability of failure due to DVD drive/disk read problems, over heating, hard drive write errors and memory overrun issues. This procedure is very detailed and should only be performed by users who are very familiar with Windows and/or DOS commands. Novice computers users should not attempt this procedure. Copying Repair data from a DVD is a time-consuming process. Depending on the speed of your processor and/or network, could easily require two or more hours per disk. For this reason, we recommend that you perform the actual copying of data during non-business evening or weekend hours.

  • 1. Xcopy 2. No, You Cannot Use the Xcopy Command in Your Assignment
    Intro to Operating Systems CNET 173 Assignment #4 Windows / LINUX Command Line Commands You are to list twenty-five command line commands of each operating system (WINDOWS and LINUX). That’s twenty- five WINDOWS commands and twenty-five LINUX commands. For each command you are to give: 1. The command a. Description/Attribute of the command b. Syntax of the command and c. A maximum of five Parameters used with the command and a description of the parameter. (If there are less than five parameters, list all parameters associated with the command.) Each command should be numbered and grouped (all WINDOWS commands with WINDOWS commands). Command information should be listed in the 1, a, b, c order listed above (i.e. command, description, syntax and parameters). This assignment must be typed and submitted through CANVAS. It should include a title page consisting of your name, course name, number, day and time, assignment name, instructor’s name, and due date and the assignment instructions. Example listed below. Windows Command Line Commands 1. xcopy a) Description - Copies files and directories, including subdirectories. b) Syntax xcopy Source [Destination] [/w] [/p] [/c] [/v] [/q] [/f] [/l] [/g] [/d[:mm-dd-yyyy]] [/u] [/i] [/s [/e]] [/t] [/k] [/r] [/h] [{/a|/m}] [/n] [/o] [/x] [/exclude:file1[+[file2]][+[file3]] [{/y|/-y}] [/z] c) Parameters /w : Displays the following message and waits for your response before starting to copy files: Press any key to begin copying file(s) /p : Prompts you to confirm whether you want to create each destination file. /c : Ignores errors. /v : Verifies each file as it is written to the destination file to make sure that the destination files are identical to the source files.

  • Older Operating Systems
    Older Operating Systems Class Notes # 10 Batch Files (Part 2) October 23, 2003 IF Condition When a given condition is true, the statement is executed. When the given condition is false, the statement is not executed. Figure one illustrates the flow chart for the IF condition. IF entry point No Decision Yes Statement (perform some action) IF exit point Figure 1: IF condition flow chart The IF condition tests the following three conditions: • The ERRORLEVEL of a program • Whether a string is equal to another string • Whether a file exists Using IF to test ERRORLEVEL The syntax for testing the ERRORLEVEL is: IF ERRORLEVEL number command This form of the IF condition determines whether the value of ERRORLEVEL is greater than or equal to a number specified in the number parameter. IF NOT ERRORLEVEL number command This form of the IF condition determines whether the value of ERRORLEVEL is not greater than or equal to a number specified in the number parameter. 1 If the specified condition is true, DOS executes the command specified in the command parameter. Otherwise, DOS skips to the next line in the batch file without executing the command in the command parameter. The only DOS commands that leave an ERRORLEVEL (exit) code are: BACKUP, DISKCOMP, DISKCOPY, FORMAT, GRAFTABL, KEYB, REPLACE, RESTORE, and XCOPY. Many other programs generate exit codes, however. For example, table one contains codes that are generated by the DISKCOPY command. Table one: DISKCOPY codes Code Description 0 The operation was successful. 1 A read/write error occurred that did not terminate the disk copy operation.

  • External Commands
    5/22/2018 External commands External commands Previous | Content | Next External commands are known as Disk residence commands. Because they can be store with DOS directory or any disk which is used for getting these commands. Theses commands help to perform some specific task. These are stored in a secondary storage device. Some important external commands are given below- MORE MOVE FIND DOSKEY MEM FC DISKCOPY FORMAT SYS CHKDSK ATTRIB XCOPY SORT LABEL 1. MORE:-Using TYPE command we can see the content of any file. But if length of file is greater than 25 lines then remaining lines will scroll up. To overcome through this problem we uses MORE command. Using this command we can pause the display after each 25 lines. Syntax:- C:\> TYPE <File name> | MORE C:\> TYPE ROSE.TXT | MORE or C: \> DIR | MORE 2. MEM:-This command displays free and used amount of memory in the computer. Syntax:- C:\> MEM the computer will display the amount of memory. 3. SYS:- This command is used for copy system files to any disk. The disk having system files are known as Bootable Disk, which are used for booting the computer. Syntax:- C:\> SYS [Drive name] C:\> SYS A: System files transferred This command will transfer the three main system files COMMAND.COM, IO.SYS, MSDOS.SYS to the floppy disk. 4. XCOPY:- When we need to copy a directory instant of a file from one location to another the we uses xcopy command. This command is much faster than copy command. Syntax:- C:\> XCOPY < Source dirname > <Target dirname> C:\> XCOPY TC TURBOC 5.
