reg compare |
Compares specified registry subkeys or entries. |
Syntax |
reg compare <keyname1> <keyname2> [{/v Valuename | /ve}] [{/oa | /od | /os | on}] [/s] |
Parameters |
Parameter |
Description |
<keyname1> |
Specifies the full path of the subkey or entry to be added. To specify a remote computer, include the computer name (in the format \\<computername>\) as part of the keyname. Omitting \\<computername>\ causes the operation to default to the local computer. The keyname must include a valid root key. Valid root keys for the local computer are: HKLM, HKCU, HKCR, HKU, and HKCC. If a remote computer is specified, valid root keys are: HKLM and HKU. If the registry key name contains a space, enclose the key name in quotes. |
<keyname2> |
Specifies the full path of the second subkey to be compared. To specify a remote computer, include the computer name (in the format \\<computername>\) as part of the keyname. Omitting \\<computername>\ causes the operation to default to the local computer. Specifying only the computer name in keyname2 causes the operation to use the path to the subkey specified in keyname1. The keyname must include a valid root key. Valid root keys for the local computer are: HKLM, HKCU, HKCR, HKU, and HKCC. If a remote computer is specified, valid root keys are: HKLM and HKU. If the registry key name contains a space, enclose the key name in quotes. |
/v <Valuename> |
Specifies the value name to compare under the subkey. |
/ve |
Specifies that only entries that have a value name of null should be compared. |
/oa |
Specifies that all differences and matches are displayed. By default, only the differences are listed. |
/od |
Specifies that only differences are displayed. This is the default behavior. |
/os |
Specifies that only matches are displayed. By default, only the differences are listed. |
/on |
Specifies that nothing is displayed. By default, only the differences are listed. |
/s |
Compares all subkeys and entries recursively. |
/? |
Displays help at the command prompt. |
<keyname1> |
\\<computername>\ |
\\<computername>\ |
<keyname2> |
\\<computername>\ |
\\<computername>\ |
<Valuename> |
