NAME¶
systemd-cat - Connect a pipeline or program's output with the journalSYNOPSIS¶
systemd-cat
[OPTIONS...] [COMMAND]
[ARGUMENTS...]
systemd-cat
[OPTIONS...]
DESCRIPTION¶
systemd-cat may be used to connect STDOUT and STDERR of a process with 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-command 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, --helpPrints a short help text and exits.
--version
Prints a short version string and exits.
-t, --identifier=
Specify a short string that is used to
identify the logging tool. If not specified no identifying 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, resp. 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 STDOUT/STDERR connected to the journal:# systemd-cat ls
# ls | systemd-cat
