SYNOPSIS
systemd-cat [options] [command] [arguments]
DESCRIPTION
systemd-cat connects a command or pipeline's output streams to the systemd journal. It is useful for logging output from cron jobs, scripts, or any command that doesn't natively support journal logging.
When run with a command, both stdout and stderr are captured. When used as a pipe target, only stdin (the pipe) is captured while stderr remains connected to the terminal.
PARAMETERS
-t, --identifier _name_
Syslog identifier for log entries-p, --priority _level_
Default priority level for stdout messages--stderr-priority _level_
Priority level for stderr messages--level-prefix
Interpret priority prefixes in log output-h, --help

CAVEATS
When used in a pipeline, only the piped output is captured. The identifier defaults to "cat" in pipe mode. Priority levels follow syslog conventions.
