What Are Some Examples of Common DOS Commands? DAILY TIME RECORD What are some examples of common DOS commands? DAILY TIME RECORD University Information Technology Services What are some examples of common DOS commands? The following is a list of useful DOS commands, with explanations. They are useful on older DOS systems and in the command-line interface on modern Windows systems. To access the command-line interface: Windows 7 or Vista: Click Start, type cmd, and then press Enter. Certain commands may require administrative access on Windows 7 or Vista. To launch the command line interface in administrative mode, click Start, type cmd, and then right-click the cmd or cmd.exe search result and choose Run as Administrator. Windows XP: Click Start, then Run. Type cmd, and then press Enter. Note: Where example files (e.g., file.ext, file1, file2), file extensions (.ext), directories (e.g., diry, diry1, diry2), commands (e.g., command), and drive letters (e.g., a:, b:, c:) are given, substitute the name of your own file, directory, command, or drive letter. Since DOS is not case-sensitive, you can type these commands in either upper- or lowercase. help List commands (only in DOS versions 5 or later). help command See help for the DOS command. command /? List switches for the DOS command. path=c:\windows;c:\dos Specify in which directories DOS searches for commands or programs. prompt $p$g Make the DOS prompt display the current directory. dir List files in the current directory in one column. dir /w List files in five columns. dir /p List files one page at a time. dir *.ext List all files with an .ext extension. dir z???.ext List files with .ext extensions that have four letters and start with z (where z is a character of your choice). dir file.ext /s Search for the file.ext in the current directory and all subdirectories under the current directory; most useful if the current directory is the root (i.e., C:\). type file.ext View the contents of the text file file.ext. edit file.ext Use the DOS editor to edit the file file.ext. a: Change to the a: drive. md c:\diry Make a new subdirectory named diry in the c:\ directory. cd c:\diry Change to subdirectory diry. rd c:\diry Remove the existing subdirectory named diry. del file.ext Delete a file named file.ext. ren file1 file2 Rename file file1 to file2. copy file1 file2 Copy file file1 to file2. verify on Turn on verification of copy commands. verify off Turn off verification of copy commands. 1 of 2 3/30/2012 6:20 PM What are some examples of common DOS commands? DAILY TIME RECORD xcopy diry1 diry2 /s Copy all files and subdirectories in directory diry1 to diry2. xcopy diry1 diry2 /p Ask for confirmation of each file before copying it from diry1 to diry2. diskcopy a: b: Duplicate a disk using two floppy drives. diskcopy a: a: Duplicate a disk using the same floppy drive. format a: Format a disk in drive a:. format a: /s Format a bootable disk (include system files). backup c:\diry\*.ext a: Back up all files with the extension .ext in c:\diry\ to drive a:. backup c:\ a: /s Back up the entire c: drive to drive a:. restore a:\ c:\diry\*.ext Restore backed-up files with the extension .ext in drive a: to the c:\diry\ directory. restore a: c:\ /s Restore backed-up files and subdirectories from drive a: to c:\. ver Check the version of DOS. time Check or correct the system time. date Check or correct the system date. cls Clear the screen. scandisk Scan and check drive c: for errors. ScanDisk replaces chkdsk (see below) on DOS version 6.0 and above (including Windows 95). chkdsk Check disk and memory usage of the current disk. chkdsk /f Fix errors reported by chkdsk. chkdsk file.ext Check a particular file. chkdsk a: Check a particular drive (in this case, a floppy in the a: drive). mem Check memory usage. This list was adapted from the August 1991 issue of PC World magazine, Instant Reference Card #15, p. 237. Copyright 2005-2010, The Trustees of Indiana University 2 of 2 3/30/2012 6:20 PM.

Description copy copies filename1 to filename2. Options public specifies that filename2 be readable by everyone; otherwise, the file will be created according to the default permissions of your operating system. text specifies that filename1 be interpreted as a text file and be translated to the native form of text files on your computer. Computers differ on how end-of-line is recorded: Unix systems record one line-feed character, Windows computers record a carriage-return/line-feed combination, and Mac computers record just a carriage return. text specifies that filename1 be examined to determine how it has end-of-line recorded and that the line-end characters be switched to whatever is appropriate for your computer when the copy is made. There is no reason to specify text when copying a file already on your computer to a different location because the file would already be in your computer’s format.

  • Attachment D to Adm. Memo No. 004 INSTRUCTIONS FOR
    Attachment D to Adm. Memo No. 004 INSTRUCTIONS FOR FORMATTING A DISKETTE Formatting is the preparation of diskettes for storage of information. There are several different versions of the format command that can be used. The version that you use depends upon the type of diskette and the type of disk drive in which the diskette is being formatted. In order for us to be able to read the Tuition Grant diskettes you send, the diskettes should be properly formatted. Below is a table that identifies the more commonly used diskette types and disk drive specifications. The correct version of the format command will appear in the row for your diskette type and drive type. The format command uses the parameter “d:” to indicate the disk drive designation. For example, your 5 ¼ drive may be the “A:” drive. Instead of typing “FORMAT D:”, replace the drive designation with “A:” and type “FORMAT A:”. To verify that the disks were formatted correctly, perform the CHKDSK command on the newly formatted diskette. The format for the CHKDSK command is “CHKDSK d:”. When the command returns the disk information, compare it to the information in the fourth column of the table that corresponds to your diskette type and disk drive.. If the “total disk space” numbers are the same, the diskette is formatted correctly. DISK TYPE DRIVE TYPE FORMAT COMMAND SPACE INFO. 5 ¼” DSDD DSDD FORMAT d: 362,496 bytes total disk space 5 ¼” DSDD HD FORMAT d: /T:40 /N:9 362,496 bytes total disk space 5 ¼” HD DSDD Cannot be formatted 5 ¼” HD HD FORMAT d: 1,213,952 bytes total disk space 3 ½” DSDD DSDD FORMAT d: 730,112 bytes total disk space 3 ½” DSDD HD FORMAT d: /T:80 /N:9 730,112 bytes total disk space 3 ½” HD DSDD Cannot be formatted 3 ½” HD HD FORMAT d: 1,457,664 bytes total disk space 3 ½” DSHD FORMAT d: 1,457,664 bytes total disk space.

  • F.A.Q. Series ROM-DOS TM
    21520 30th Drive SE #110 Bothell, WA 98021 USA Tel: (425) 951-8086 Fax: (425) 951-8095 [email protected] [email protected] www.datalight.com TM ROM-DOS F.A.Q. Series Question: Assuming they don't want FAT32, Long Filename support, or Sockets, why should my customer upgrade to the newest ROM-DOS? Answer: Since our first FAT32 and LFN release 4.00.1091, there have been several improvements to the core ROM- DOS kernel. This core code is used primarily for our DOS 6.22 compatible compilations, and then extended in the case of a FAT32 or Long Filename build. The 4.00.1091 release is also a new code base and there will be no further upgrades to the previous DOS 6.22 code. In order to obtain new features, fixes, and support a customer must upgrade to release 4.00.1091 or greater. Along with the performance enhancements for both size and speed, several corrections have been made to the ROM-DOS kernel. These include stack and memory issues, disk access issues, and compatibility with the former market leader in DOS. Most of the ROM-DOS utilities have also been improved for size and speed, along with bug fixes. The major changes happened with the XCOPY, HIMEM, MSCDEX, CHKDSK, FDISK and FORMAT utilities. In the realm of international support, the Euro was added to the keyboard and display driver code. ROM- DOS and PC-DOS 2000 are the only non-GUI operating systems to support the Euro. Finally, new ROM-DOS utilities have been added.

  • TRSDOS 6.2 to LS-DOS 6.3.0 Manual Update
    LS-DOSÔ 6.3 UPDATE FOR TRSDOSâ 6.2.X The LS-DOS 6.3 release is an upgrade for the TRSDOS 6.2 operating system. Several important changes have been made to extend and enhance the operating system and its utilities. The date ranging has been expanded to accept dates through the year 1999. Files will now carry a modification time as well as a date. The DATECONV/CMD program is provided to translate version 6.2 or earlier disks to the 6.3 style dating. The user password has been eliminated from the system. The owner password still remains. The library command ID was added to display a customer service number. Several enhancements have been made to BASIC. The new DISKCOPY/CMD program will duplicate 5" double density floppy disks. Because the LS-DOS 6.3 update is a series of enhancements to TRSDOS 6.2, the primary documentation remains the 6.2 manual and Technical Reference manual. If you have a version of TRSDOS earlier than 6.2, you can obtain the manuals from Radio Shack under the catalog numbers 26-0316 (TRSDOS Version 6 [6.2 DOS manual and disk]), 26-2110 (Model 4/4D [6.2] Technical Reference Manual), or 26-1117 (6.2 DOS manual only). This documentation should be treated as an addendum to the TRSDOS 6.2 information. LS-DOS 6.3 installation instructions Before performing the upgrade, it is recommended that you make several backup copies of the 6.3 master disk. The simplest way to do this is to boot your system using the 6.3 diskette, insert a blank diskette to receive the copy in drive 1, and type the command: DISKCOPY :0 :1 When the copy finishes, you can insert another destination diskette and make another copy.

  • Mac Keyboard Shortcuts Cut, Copy, Paste, and Other Common Shortcuts
    Mac keyboard shortcuts By pressing a combination of keys, you can do things that normally need a mouse, trackpad, or other input device. To use a keyboard shortcut, hold down one or more modifier keys while pressing the last key of the shortcut. For example, to use the shortcut Command-C (copy), hold down Command, press C, then release both keys. Mac menus and keyboards often use symbols for certain keys, including the modifier keys: Command ⌘ Option ⌥ Caps Lock ⇪ Shift ⇧ Control ⌃ Fn If you're using a keyboard made for Windows PCs, use the Alt key instead of Option, and the Windows logo key instead of Command. Some Mac keyboards and shortcuts use special keys in the top row, which include icons for volume, display brightness, and other functions. Press the icon key to perform that function, or combine it with the Fn key to use it as an F1, F2, F3, or other standard function key. To learn more shortcuts, check the menus of the app you're using. Every app can have its own shortcuts, and shortcuts that work in one app may not work in another. Cut, copy, paste, and other common shortcuts Shortcut Description Command-X Cut: Remove the selected item and copy it to the Clipboard. Command-C Copy the selected item to the Clipboard. This also works for files in the Finder. Command-V Paste the contents of the Clipboard into the current document or app. This also works for files in the Finder. Command-Z Undo the previous command. You can then press Command-Shift-Z to Redo, reversing the undo command.

  • 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.
