The default value is 10 if no argument is given. Show the most recent journal events and limit the number of events shown. Note that this option is only supported for the To guarantee that the pager will not buffer logs of unbounded size. Immediately jump to the end of the journal inside the implied pager tool. Show only the most recent journal entries, and continuously print new entries as they are appended to the journal. (Note that the pager may escape unprintable characters again.) By default, fields with unprintable characters are abbreviated as "blob data". Show all fields in full, even if they include unprintable characters or are very long.

The default is to show full fields, allowing them to wrap or be truncated by the pager, if one is used.

Because device nodes generally change their corresponding devices across reboots, specifying a device node path causes the resulting entries to be restricted to those from the current boot.Īdditional constraints may be added using options For the resulting log entries to be correct for the actual device, the relevant parts of the environment at the time the entry was logged, in particular the actual device corresponding to the device node, must have been the same as those at the time of the query. In general, a device node is the best proxy for an actual device, as log entries do not usually contain fields that identify an actual device. Symbolic links are dereferenced, kernel names are synthesized, and parent devices are identified from the environment at the time of the query. Matches for the kernel name of the device and for each of its ancestor devices is added to the query. Match for the script name is added to the query. If a file path refers to an executable script, a Match for the canonicalized binary path is added to the query. If a file path refers to an executable binary, an The file path may be a file or a symbolic link and the file must exist at the time of the query. It is also possible to filter the entries by specifying an absolute file path as an argument. This causes all matches before and after to be combined in a disjunction (i.e.
May appear as a separate word between other terms on the command line. the resulting output will show entries matching any of the specified matches for the same field. If two matches apply to the same field, then they are automatically matched as alternatives, i.e. the resulting output will show only entries matching all the specified matches of this kind. If multiple matches are specified matching different fields, the log entries are filtered by both, i.e. "_SYSTEMD_UNIT=rvice", referring to the components of a structured journal entry. If one or more match arguments are passed, the output is filtered accordingly. If called without parameters, it will show the full contents of the journal, starting with the oldest entry collected.
