SYSTEMD-CAT(1)                    systemd-cat                   SYSTEMD-CAT(1)

NAME
       systemd-cat - Connect a pipeline or program's output with the journal
SYNOPSIS
       systemd-cat [OPTIONS...] [COMMAND] [ARGUMENTS...]
       systemd-cat [OPTIONS...]
DESCRIPTION
       systemd-cat may be used to connect the standard input and output of a
       process to the journal, or as a filter tool in a shell pipeline to pass
       the output the previous pipeline element generates to the journal.
       If no parameter is passed, systemd-cat will write everything it reads
       from standard input (stdin) to the journal.
       If parameters are passed, they are executed as command line with
       standard output (stdout) and standard error output (stderr) connected
       to the journal, so that all it writes is stored in the journal.
OPTIONS
       The following options are understood:
       -h, --help
           Print a short help text and exit.
       --version
           Print a short version string and exit.
       -t, --identifier=
           Specify a short string that is used to identify the logging tool.
           If not specified, no identification string is written to the
           journal.
       -p, --priority=
           Specify the default priority level for the logged messages. Pass
           one of "emerg", "alert", "crit", "err", "warning", "notice",
           "info", "debug", or a value between 0 and 7 (corresponding to the
           same named levels). These priority values are the same as defined
           by syslog(3). Defaults to "info". Note that this simply controls
           the default, individual lines may be logged with different levels
           if they are prefixed accordingly. For details see --level-prefix=
           below.
       --level-prefix=
           Controls whether lines read are parsed for syslog priority level
           prefixes. If enabled (the default), a line prefixed with a priority
           prefix such as "<5>" is logged at priority 5 ("notice"), and
           similar for the other priority levels. Takes a boolean argument.
EXIT STATUS
       On success, 0 is returned, a non-zero failure code otherwise.
EXAMPLES
       Example 1. Invoke a program
       This calls /bin/ls with standard output and error connected to the
       journal:
           # systemd-cat ls
       Example 2. Usage in a shell pipeline
       This builds a shell pipeline also invoking /bin/ls and writes the
       output it generates to the journal:
           # ls | systemd-cat
       Even though the two examples have very similar effects the first is
       preferable since only one process is running at a time, and both stdout
       and stderr are captured while in the second example, only stdout is
       captured.
