Help me with a batch file

[xcharge50]

If he's examining windows versions, there is a chance he wants the batch to run on windows 98, in which case SET /P is not available.

You right! In other word : I'm attempting to make my batch the more compatible possible

If you are making your script backwards compatible with Win9x, then be sure to modify your IPCONFIG commands because the Win9x version of IPCONFIG is very different from the Windows 2000 / Windows XP version of IPCONFIG

Code: [Select]

C:\Win98>ipconfig /?
Windows 98 IP Configuration
Command line options:
 /All - Display detailed information.
 /Batch [file] - Write to file or ./WINIPCFG.OUT
 /renew_all    - Renew   all adapters.
 /release_all  - Release all adapters.
 /renew   N    - Renew   adapter N.
 /release N    - Release adapter N.

Code: [Select]

C:\WindowsXP>ipconfig /?
USAGE:
    ipconfig [/? | /all | /renew [adapter] | /release [adapter] |
              /flushdns | /displaydns | /registerdns |
              /showclassid adapter |
              /setclassid adapter [classid] ]

where
    adapter         Connection name
                   (wildcard characters * and ? allowed, see examples)

    Options:
       /?           Display this help message
       /all         Display full configuration information.
       /release     Release the IP address for the specified adapter.
       /renew       Renew the IP address for the specified adapter.
       /flushdns    Purges the DNS Resolver cache.
       /registerdns Refreshes all DHCP leases and re-registers DNS names
       /displaydns  Display the contents of the DNS Resolver Cache.
       /showclassid Displays all the dhcp class IDs allowed for adapter.
       /setclassid  Modifies the dhcp class id.

The default is to display only the IP address, subnet mask and
default gateway for each adapter bound to TCP/IP.

For Release and Renew, if no adapter name is specified, then the IP address
leases for all adapters bound to TCP/IP will be released or renewed.

For Setclassid, if no ClassId is specified, then the ClassId is removed.

Examples:
    > ipconfig                   ... Show information.
    > ipconfig /all              ... Show detailed information
    > ipconfig /renew            ... renew all adapters
    > ipconfig /renew EL*        ... renew any connection that has its
                                     name starting with EL
    > ipconfig /release *Con*    ... release all matching connections,
                                     eg. "Local Area Connection 1" or
                                         "Local Area Connection 2"
