NAME
     zgenhostid -- generate host ID into /etc/hostid

SYNOPSIS
     zgenhostid [-f] [-o filename] [hostid]

DESCRIPTION
     Creates  /etc/hostid file and stores the host ID in it.  If hostid was pro-
     vided, validate and store that value.  Otherwise, randomly generate an ID.

OPTIONS
     -h 	  Display a summary of the command-line options.

     -f 	  Allow output overwrite.

     -o filename  Write to filename instead of the default /etc/hostid.

     hostid	  Specifies the value to be placed in /etc/hostid.  It should be
		  a number with a value between 1 and 2^32-1.  If 0, generate  a
		  random  ID.  This value must be unique among your systems.  It
		  must be an 8-digit-long hexadecimal  number,	optionally  pre-
		  fixed by "0x".

FILES
     /etc/hostid

EXAMPLES
     Generate a random hostid and store it
	       # zgenhostid

     Record the libc-generated hostid in /etc/hostid
	       # zgenhostid "$(hostid)"

     Record a custom hostid (0xdeadbeef) in /etc/hostid
	       # zgenhostid deadbeef

     Record  a	custom hostid (0x01234567) in /tmp/hostid and overwrite the file
	 if it exists
	       # zgenhostid -f -o /tmp/hostid 0x01234567
