Generate UUID for a host
Hello Experts,
Is there a way to generate Universally Unique identifiers on all Unix flavours such as Solaris, RHELinux,Suse Linux, MacOS,HP UX etc?
If i can get a system command or a system call or an algorithm/script/program to generate a unique identifier, it will be helpful.
Thanks in advance.

uuid_gen
uuid_gen(1ncs) uuid_gen(1ncs)
Name
uuid_gen - UUID generating program
Syntax
/etc/ncs/uuid_gen [ -c ] [ -C ] [ -version ]
Description
The program generates Universal Unique Identifiers (UUIDs). Without options, it generates a character-string representation of a UUID.
The -c option enables you to generate a template for Network Interface Definition Language (NIDL) files. The -C option enables you to gen-
erate source-code representations of UUIDs, suitable for initializing variables of type
Options
-c Generate a template, including a UUID attribute, for an interface definition in the C syntax of NIDL.
-C Generate a C source-code representation of a UUID.
-version Display the version of the Network Computing Kernel (NCK) that this belongs to but do not generate a UUID. (NCK is part of the
Network Computing System (NCS) on which DECrpc is based.)
Examples
Generate a character-string representation of a UUID:
$ /etc/ncs/uuid_gen
34dc23469000.0d.00.00.7c.5f.00.00.00
Generate a template for an interface definition in the C syntax of NIDL:
$ /etc/ncs/uuid_gen -c
%c
[
uuid(34dc239ec000.0d.00.00.7c.5f.00.00.00),
version(1)
]
interface INTERFACENAME {
}
Generate a template for an interface definition in the C syntax of NIDL. Redirect the output to the file
$ /etc/ncs/uuid_gen -c >myfile.idl
Generate a C source-code representation of a UUID:
$ /etc/ncs/uuid_gen -C
= { 0x34dc23af,
0xf000,
0x0000,
0x0d,
{0x00, 0x00, 0x7c, 0x5f, 0x00, 0x00, 0x00} };
