Read line from file randomly

I have data file with customer.dat, and this contains the
HTML Code:
customer names
>cat customer.dat
FirstName1 LastName1
FistName2 LastName1
FistName3 MiddleName3 LastName3
This file can contain areoun 100 customer names.

Quote:
My requirement is to get the customer complete name randomly, I want to use RANDOM to generate random number, and then I want to read the complete name from the customer.dat with line number that matches with the random number

Any idea how to read the file if the line number is specified?
Regards,

NAME
fruadm - prints and updates customer data associated with FRUs SYNOPSIS
/usr/platform/sun4u/sbin/fruadm /usr/platform/sun4u/sbin/fruadm -l /usr/platform/sun4u/sbin/fruadm [-r] path [text] DESCRIPTION
fruadm prints or sets the customer data for Field-Replaceable Units (FRUs). Without arguments, fruadm prints the paths of all FRU ID-capable FRUs (containers) in the system, along with the contents of the customer data record, if present, for each such FRU; for FRUs without customer data, fruadm prints only the container's path. Only a privileged user can create or update data in containers. The privileges required to perform these write operations are hardware dependent. Typically, a default system configuration restricts write operations to the superuser or to the platform-administrator user. OPTIONS
The following options are supported: -l List the system's frutree paths. -r Recursively display or update the data for all containers rooted at the argument path. OPERANDS
The following operands are supported: path A full or partial system frutree path for or under which to print or set the customer data. The first field of each line of output of fruadm -l gives the valid full frutree paths for the system. Paths can include shell meta-characters; such paths should be quoted appropriately for the user's shell. For par- tial paths, the first matching full path is selected for display or update. Without the -r option, the path must be that of a container; with the -r option, all containers (if any) under path will be selected. text Up to 80 characters of text set as the customer data. If the text contains white space or shell metacharacters, it should be quoted appropriately for the user's shell. EXAMPLES
Example 1: Displaying All Customer Data The following example prints all customer data available from FRUs on the system. For containers with no customer data, only the contain- ers' paths will be listed. example% fruadm Example 2: Displaying Customer Data For a Single FRU The following command prints the customer data, if present, for the specified FRU: example% fruadm /frutree/chassis/system-board Example 3: Displaying Customer Data For a Single FRU The following command prints the customer data, if present, for the first mem-module found: example% fruadm mem-module Example 4: Setting Customer Data The following example sets the customer data for a FRU: example# fruadm system-board 'Asset Tag 123456' Example 5: Setting Customer Data The following command sets the customer data for all FRUs under chassis: example# fruadm -r /frutree/chassis "Property of XYZ, Inc." EXIT STATUS
The following exit values are returned: 0 Successful completion. >0 An error occurred. ATTRIBUTES
