Command:

Usage:



ATTRIB

Displays or changes file attributes.

ATTRIB [+R | -R] [+A | -A] [+S | -S] [+H | -H] [[drive:][path]filename] [/S]

+ Sets an attribute.- Clears an attribute.R Read-only file attribute.A Archive file attribute.S System file attribute.H Hidden file attribute./S Processes files in all directories in the specified path.

attrib +r autoexec.bat - This would make the autoexec.bat so it cannot be modified until the read only attribute is taken off.

attrib +h io.sys - This would make the config.sys hidden so to the average user this file would not be existent however if the attrib command it typed alone "attrib" this will show any hidden files.

attrib -h io.sys - This command will do the apposite of the above command. Instead of hiding the file it will unhide the file if hidden.

ARP

ARP -s [inet_addr] [eth_adr] [if_addr] ARP -d [inet_addr] [if_addr] ARP -a [inet_addr] [-N if_addr]



-a Displays current ARP entries by interrogating the current protocol data. If inet_addr is specified, the IP and Physical addresses for only the specified computer are displayed. If more than one network interface uses ARP, entries for each ARP table are displayed.

-g Same as -ainet_addr Specifies an internet address.-N if addr Displays the ARP entries for the network interface specified by if_addr.-d Deletes the host specified by inet_addr.-s Adds the host and associates the Internet address inet_addr with the Physical address eth_addr. The Physical address

is given as 6 hexadecimal bytes seperated by hyphens. The entry is permanent.eth_addr Specifies a physical addressif_addr If present, this specifies the Internet address of the interface whose address translation table should be modified. If not

present, the first applicable interface will be used.

arp -a

Interface 220.0.0.80

Internet Address Physical Address Type 220.0.0.160 00-50-04-62-F7-23 static

The Physical Address as shown above in the format aa-bb-cc-dd-ee-ff is the unique manufacture identification number. This number should always be a unique address.

An example of how to change the above IP address 220.0.0.160 to 220.0.0.161 in this case would be:

arp -s 220.0.0.161 00-50-04-62-F7-23

It is important to not that if a IP address has already been assigned to the specific network adapter it is not possible to change that assigned IP address to a new address. In addition networks italicizing DHCP, BOOTP or RARP will automatically assign the card an IP address therefore this command would not be utilized.

CD,MD,RD

CD Changes current directory



CHDIR [drive:][path] CHDIR[..] CD [drive:][path] CD[..]

MD Creates a directory.

MKDIR [drive:]path MD [drive:]path

CHKDSK

Checks a disk and displays a status report.

Type CHKDSK without parameters to check the current disk.

Instead of using CHKDSK, try using SCANDISK. SCANDISK can reliably detect and fix a much wider range of disk problems.

chkdsk = Will display all information described above and also report any crossed linked files. http://www.techtips4u.com/kb/sw/SW00021.htm (5 of 23) [9/1/2009 6:16:49 PM]
