       systemd-cat - Connect a pipeline or program's output with the journal


       systemd-cat [OPTIONS...] [COMMAND] [ARGUMENTS...]

       systemd-cat [OPTIONS...]


       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.


       The following options are understood:

       -h, --help
           Print a short help text and exit.

           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.

           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


       On success, 0 is returned, a non-zero failure code otherwise.


       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.
