POSTCAT(1) POSTCAT(1)
<b>NAME</b>
postcat - show Postfix queue file contents
<b>SYNOPSIS</b>
<b>postcat</b> [<b>-bdehnoqv</b>] [<b>-c</b> <i>config</i><b>_</b><i>dir</i>] [<i>files</i>...]
<b>DESCRIPTION</b>
The <a href="postcat.1.html"><b>postcat</b>(1)</a> command prints the contents of the named <i>files</i> in
human-readable form. The files are expected to be in Postfix queue file
format. If no <i>files</i> are specified on the command line, the program
reads from standard input.
By default, <a href="postcat.1.html"><b>postcat</b>(1)</a> shows the envelope and message content, as if
the options <b>-beh</b> were specified. To view message content only, specify
<b>-bh</b> (Postfix 2.7 and later).
Options:
<b>-b</b> Show body content. The <b>-b</b> option starts producing output at the
first non-header line, and stops when the end of the message is
reached.
This feature is available in Postfix 2.7 and later.
<b>-c</b> <i>config</i><b>_</b><i>dir</i>
The <a href="postconf.5.html"><b>main.cf</b></a> configuration file is in the named directory instead
of the default configuration directory.
<b>-d</b> Print the decimal type of each record.
<b>-e</b> Show message envelope content.
This feature is available in Postfix 2.7 and later.
<b>-h</b> Show message header content. The <b>-h</b> option produces output from
the beginning of the message up to, but not including, the first
non-header line.
This feature is available in Postfix 2.7 and later.
<b>-o</b> Print the queue file offset of each record.
<b>-q</b> Search the Postfix queue for the named <i>files</i> instead of taking
the names literally.
This feature is available in Postfix 2.0 and later.
<b>-v</b> Enable verbose logging for debugging purposes. Multiple <b>-v</b>
options make the software increasingly verbose.
<b>DIAGNOSTICS</b>
Problems are reported to the standard error stream.
<b>ENVIRONMENT</b>
<b>MAIL_CONFIG</b>
