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 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, --helpPrint 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
# ls | systemd-cat
