The advantage of using praliases (rather than makemap -u) is that praliases
reads the sendmail configuration file to find the location and type of the aliases database.
As a bonus, praliases prints the contents of all aliases databases. For example,
consider a part of your mc configuration file that looks like this:
define(`ALIAS_FILE??, `hash:/etc/mail/aliases/users,btree:/etc/mail/aliases/clients??)
Here, the /etc/mail/aliases/users.db file will be created by newaliases as a hash-type
database, and the file /etc/mail/aliases/clients.db will be created as a btree-type database.
If you ran praliases on this setup, it would first print all the aliases in the first
file, followed by all the aliases in the second file, correctly detecting the type for each.
The praliases program reads the sendmail.cf file to find the location and types of
aliases files. A command-line switchallows you to point to a different configuration

file. Another allows you to specify a particular aliases database file. Those switches
are outlined in Table 10-7, and explained in the sections that follow.
The output produced by praliases is different from that produced by makemap -u.
The praliases program lists the key on the left and data for that key on the right, separated
by a colon.
