NAME<br />
postalias - <strong>Postfix</strong> alias database maintenance<br />
SYNOPSIS<br />
postalias [-Ninrvw] [-c config_dir] [-d key] [-q key]<br />
[file_type:]file_name ...<br />
DESCRIPTION<br />
The postalias command creates or queries one or more <strong>Postfix</strong><br />
alias databases, or updates an existing one. The input<br />
and output file formats are expected to be compatible with<br />
Sendmail version 8, and are expected to be suitable for<br />
the use as NIS alias maps.<br />
While a database update is in progress, signal delivery is<br />
postponed, and an exclusive, advisory, lock is placed on<br />
the entire database, in order to avoid surprises in spectator<br />
programs.<br />
Options:<br />
-N Include the terminating null character that terminates<br />
lookup keys and values. By default, <strong>Postfix</strong><br />
does whatever is the default for the host operating<br />
system.<br />
-c config_dir<br />
Read the main.cf configuration file in the named<br />
directory instead of the default configuration<br />
directory.<br />
-d key Search the specified maps for key and remove one<br />
entry per map. The exit status is zero when the<br />
requested information was found.<br />
If a key value of - is specified, the program reads<br />
key values from the standard input stream. The exit<br />
status is zero when at least one of the requested<br />
keys was found.<br />
-i Incremental mode. Read entries from standard input<br />
and do not truncate an existing database. By<br />
default, postalias creates a new database from the<br />
entries in file_name.<br />
-n Don't include the terminating null character that<br />
terminates lookup keys and values. By default,<br />
<strong>Postfix</strong> does whatever is the default for the host<br />
operating system.<br />
-q key Search the specified maps for key and print the<br />
first value found on the standard output stream.<br />
The exit status is zero when the requested information<br />
was found.<br />
If a key value of - is specified, the program reads<br />
key values from the standard input stream and<br />
prints one line of key: value output for each key<br />
that was found. The exit status is zero when at<br />
least one of the requested keys was found.<br />
