     ALIASHASH(ADM)	      XENIX System V		ALIASHASH(ADM)

     Name
	  aliashash - Micnet alias hash table generator.

     Syntax
	  aliashash [ -v ] [ -o output-file ] [ input-file ]

     Description
	  The aliashash command reads the input-file and generates an
	  output-file containing a hash table of alias definitions for
	  a Micnet network.  The input-file must name a file
	  containing alias definitions in the form described for the
	  aliases file (see aliases(M)).  If the -o option is not used
	  to specify an output-file, the command creates a file with
	  the same name as the input-file but with .hash appended to
	  it.  If no input-file is given, the command reads the file
	  named /usr/lib/mail/aliases and creates the file named
	  /usr/lib/mail/aliases.hash.

	  If invoked with the -v option, the command lists information
	  about the hash table.

	  The output-file will contain both the alias definitions
	  given in the input-file and the new hash table.  The hash
	  table appears at the beginning of the file and is separated
	  from the alias definitions by a blank line.  The hash table
	  has three or more lines.  The first line is:

	       #<hash>

	  The second line has 4 entries: the bytes per table entry,
	  the maximum number of items per hash value, the number of
	  entries in the table, and the offset (in bytes) from the
	  beginning of the file to the beginning of the alias
	  definitions.

	  The next lines (up to the end of the hash table) contain the
	  hash table entries.	Each line has 8 entries (separated by
	  spaces) and each entry has 2 fields.	The first field (1
	  byte) is a checksum (represented as a printable character);
	  the second field is a pointer (in bytes) to the alias
	  definition. The pointer is represented as a hexadecimal
	  number with leading blanks if necessary and is always
	  relative to the start of the definitions.

	  The aliashash command is normally invoked by the install
	  option of the netutil command.  If the alias definitions of
	  a network must be changed, the definitions in the aliases
	  file should be changed and a new aliases.hash file created
	  using the aliashash command.	The new aliases.hash file must
	  then be copied to all other computers in the network.

     Warning
	  Do not use the aliashash command to create the aliases.hash
	  file while the network is running.  If necessary, create a
	  temporary output file, aliases.hash+ , using the -o option,
	  then enter:

	       mv aliases.hash+ aliases.hash

	  This will prevent disruption of the network.
