COM file. COMP Compares the contents of two files or sets of files. To compare sets of files, use wildcards in data1 and data2 parameters. Directories will be marked so that files added afterward will be compressed.
Directories will be marked so that files added afterward will not be compressed. Default "dir" is the current directory. Already-compressed files are skipped by default. You may use multiple filenames and wildcards. All opened handles to the volume would then be invalid. Default is to prompt on overwrites unless COPY command is being executed from within a batch script.
DEBUG [[drive:][path]filename [testfile-parameters]] [drive:][path]filename Specifies the file you want to test. After Debug starts, type? Wildcards may be used to delete multiple files. If a directory is specified, all files within the directory will be deleted. Prompts for input if omitted. A valid source can be any string and should represent the application or component that is generating the event.
A valid custom message ID is in the range of 1 - This is the default. If no short name is present, blanks are displayed in its place. The two floppy disks must be the same type. You may specify the same drive for drive1 and drive2. Allows multiple commands in a macro. Not valid for signed drivers. Wildcards and multiple filespecs can be given. Environment changes made after ENDLOCAL has been issued are not local to the batch file; the previous settings are not restored on termination of the batch file.
EXE program command interpreter or the current batch script. If executed from outside a batch script, it will quit CMD. EXE exitCode specifies a numeric number.
If quitting CMD. EXE, sets the process exit code with that number. If a path is not specified, FIND searches the text typed at the prompt or piped from another command.
Regular expression quick reference:. Wildcards may be used. If set is just a single period. Each file is opened, read and processed before going on to the next file in filenameset. Processing consists of reading in the file, breaking it up into individual lines of text and then parsing each line into zero or more tokens. The body of the for loop is then called with the variable value s set to the found token string s.
Blank lines are skipped. You can override the default parsing behavior by specifying the optional "options" parameter. This is a quoted string which contains one or more keywords to specify different parsing options. This replaces the default delimiter set of space and tab. This will cause additional variable names to be allocated.
The m-n form is a range, specifying the mth through the nth tokens. For file names that contain spaces, you need to quote the filenames with double quotes. In order to use double quotes in this manner, you also need to use the usebackq option, otherwise the double quotes will be interpreted as defining a literal string to parse.
Remember, FOR variables are single-letter, case sensitive, global, and you can't have more than 52 total active at any one time. It will be treated as a single line of input from a file and parsed. You do this by making the filenameset between the parenthesis a back quoted string. It will be treated as a command line, which is passed to a child CMD.
EXE and the output is captured into memory and parsed as if it was a file. In addition, substitution of FOR variable references has been enhanced. All opened handles to the volume would no longer be valid. Default settings are strongly recommended for general use. NTFS compression is not supported for allocation unit sizes above Ftp can be used interactively. FTP [-v] [-d] [-i] [-n] [-g] [-s:filename] [-a] [-w:windowsize] [-A] [host] -v Suppresses display of remote server responses.
Type FTYPE without parameters to display the current file types that have open command strings defined. FTYPE is invoked with just a file type, it displays the current open command string for that file type. Specify nothing for the open command string and the FTYPE command will delete the open command string for the file type.
GOTO label label Specifies a text string used in the batch program as a label. You type a label on a line by itself, beginning with a colon. This is an easy way to exit a batch script file without defining a label.
HELP [command] command - displays help information on that command. ELSE echo filename. These comparisons are generic, in that if both string1 and string2 are both comprised of all numeric digits, then the strings are converted to numbers and a numeric comparison is performed. The first version is 1. It will be incremented by one when significant enhancements are added to the Command Extensions.
Show information. MODE Configures system devices. It must be used to check the hard drive and system files for errors. Many times your computer system becomes less responsive, slow or sometimes even freezes. But nothing to worry provided you run Windows XP chkdsk. Chkdsk can be run as a command-line application or it can be run with a graphical user interface. You can run it accordingly.
But what to do, if corruption strikes early? Are you prepared with your backups? It'll also save you gigs of space to boot That's not really true, I'm afraid. A boot sector is a boot sector. Adding another OS shouldn't slow down the OS in the slightest. Also, the center of the disk is not the fastest. God Bless. I used my operating system cd to get it to started back.
It came back on but it partition my hard drive. I have a back up file on my C drive. Can I change those two files back and restore it or is there anything else I can do to restore my computer back the way it was? Saved on of my client's Production server on Windows NT. I'd suggest hooking you disk up to another system using a USB enclosure is the easiest way to do it , back up any data you can pull off it and replace the disk.
The blue screen appears before I can get so far. Your solution works fine for me. It is clear and easy to learn. You deserved a 10! I'm not posting this to slam the article - I loved it! It sent me looking in the right direction and taught me way more about Recovery Console than I ever knew. I love the part where it states "Neither of these procedures are cheap in the realm of commercial PC repair, nor do they inspire a tremendous level of confidence in the technician or the hopeful client.
But thanks geeksquad, because if it wasn't for you guys i wouldn't be so busy fixing the problems you either couldn't or caused. It worked form me. I am going to save this webpage in my Bookmarks. Much better than saving all data first and then formatting and reinstalling Windows. I've spent three maddened days without access to my PC changing ribbon cables, testing different drives and all sorts of crap.
Now I'm back online and typing this comment. But I wished someone would have told us newbbies the Windows disk may not be boot-able until you run it from the "safe mode" screen and press any key within 4 seconds! I started checking for problems with my cd drive because it wasn't auto running. And in a less painful way. As the techniques given here perfectly illustrate, Windows' recovery options are nothing but a bad joke.
How do we eliminate one of those options? I'm bringin' the Yankee pain. That's because in the likely event the registry breaks enough to break Windows altogether, there's nothing you can do about it but reinstall. The registry pretty much guarantees that NO rescue disk whatsoever will succeed at fixing Windows if the problem lies within its stores. Compound this problem with the fact that the registry has a horribly low tolerance for invalid data stored inside it, no matter how innocuous.
No boot disk can access it, not even Microsoft'd own crippled recovery console can do anything about it. This, along with things like drive letter access, the fact that its still really a single-user system, and the fact that Microsoft can't secure it properly largely BECAUSE it's a single user system, are all reasons why Windows is a horribly inferior operating system.
Poorly designed. VERY poorly designed. To the point you only get a handful of options for even fixing it if it breaks before you have to reinstall it. Which is horrible because the drive letter system makes reinstalling it a real hassle, as not only do you have to reinstall your software, but backup and reinstall ALL your data.
You can fix both with even basic text editors from boot disks, no matter what the configuration is that's broken. I can even fix a broken initramfs from a boot disk. Swipe up to show the Apps screen. You can accomplish the same thing with a mouse by clicking on the down arrow icon at the bottom of the screen.
Prior to the Windows 8. If you're using a keyboard or mouse, a really quick way to open a Command Prompt window in Windows 8 is through the Power User Menu—just hold the WIN and X keys down together, or right-click the Start button , and choose Command Prompt. Swipe or scroll to the right on the Apps screen to locate the Windows System section heading.
You can now execute whatever command you needed to run.
