postcat (1) - Linux Manuals
NAME
postcat - show Postfix queue file contents
SYNOPSIS
postcat [-bdehnoqv] [-c config_dir] [files...]
DESCRIPTION
The postcat(1) command prints the contents of the named files in human-readable form. The files are expected to be in Postfix queue file format. If no files are specified on the command line, the program reads from standard input.By default, postcat(1) shows the envelope and message content, as if the options -beh were specified. To view message content only, specify -bh (Postfix 2.7 and later).
Options:
- -b
-
Show body content. The -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.
- -c config_dir
- The main.cf configuration file is in the named directory instead of the default configuration directory.
- -d
- Print the decimal type of each record.
- -e
-
Show message envelope content.
This feature is available in Postfix 2.7 and later.
- -h
-
Show message header content. The -h 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.
- -o
- Print the queue file offset of each record.
- -q
-
Search the Postfix queue for the named files instead
of taking the names literally.
This feature is available in Postfix 2.0 and later.
- -v
- Enable verbose logging for debugging purposes. Multiple -v options make the software increasingly verbose.
