# Installed product and version display: nmsabout

Use this utility to view names and version information for NMS products installed in the NMS root directory, and for Windows installations, in the system_root\system32 directory.

#### Usage

nmsabout [options]

where options are:

Option | Use this option to...
--- | ---
-h | Access help.
product_name | Display the NMS product name and base version number followed by version information for each installed product file. If a file was not installed during the original installation, the utility displays the origin of the file (either patch or service pack).
-f filename | Display the NMS product name and version number of each file that matches the file name specified. For the utility to locate the file, the file must be in the same directory in which it was originally installed. Note: When entering a file name, enter just the name of the file, not a complete path.
-x product | Display the NMS product name and base version number followed by version information on all existing product files that were not installed during the original installation. If a file is associated with a patch or service pack that you installed, the utility displays the patch or service pack number. It also displays the number of files that have changed since the original installation, as well as the total number of installed files.

#### Description

Each Natural Access product contains a signature file (.sgn) that lists each file associated with the product. A signature of checksum information and a full path uniquely identify each associated file.

nmsabout uses the signature file to display the name and version information of product files that are on your system. For example, ctaccess.sgn lists 100 files. To access information for the files on your system, enter the following command at the prompt:

nmsabout ctaccess

nmsabout displays information for the 75 files on your system.

If you request information on a product file that does not match any file listed in the signature file, you receive one of the following error messages:

Error message | Meaning
--- | ---
unknown | The file for which you requested information is located on your system. Although the path of the file matches the path in the signature file, the checksum information does not match.
not NMS file | The file for which you requested information exists on your system, but it is not listed in any signature file. Ensure that the file is in its original installation directory.
file not found | The file for which you requested information does not exist on your system.

#### Procedure

To run nmsabout, enter the following command at the prompt:

nmsabout [option]

For example, if you enter the following command:

nmsabout -x ctaccess

nmsabout lists the ctaccess product name and base version number followed by version information on all existing ctaccess files that were not installed during the original installation. If a file is associated with a patch or service pack that you installed, the utility displays the patch or service pack number. It also displays the number of files that have changed since the original installation, as well as the total number of installed files.
