newaliases rebuilds the random access data base for the mail aliases file /etc/mail/aliases.
newaliases accepts all the flags that sendmail(1M) accepts. However, most of these flags have no effect, except for the –C option and three of the Processing Options that can be set from a configuration file with the –o option:
Use alternate configuration file.
Specify possible alias files.
Set the default log level to n. Defaults to 9.
Validate the RHS of aliases when rebuilding the aliases(4) database.
newaliases runs in verbose mode (–v option) automatically.
The following command runs newaliases on an alias file different from the /etc/mail/aliases default in sendmail(1M):
example% newaliases –oA/path/to/alternate/alias/file
newaliases returns an exit status describing what it did. The codes are defined in /usr/include/sysexits.h.
