11.2.1 radlast Command Line Options

Use following command line options to control the behavior of the radlast utility:

-number

-c number

--count=number

When given this option, radlast will output at most this many lines of information.

-f

--file=name

Read the specified file instead of the default /var/log/radwtmp.

-h hostname

--host=hostname

Report the logins from given host. Host can be either a name or a dotted-quad Internet address.

-n shortname

--nas=shortname

Report the logins from the given NAS.

-l

--long-format

Long output format. Report all the information stored in radwtmp file.

-p number

--port=number

Report the logins on a given port. The port may be specified either fully or abbreviated, e.g. radlast -p S03 or radlast -p 3.

-s

--show-seconds

Report the duration of the login session in seconds instead of the default days, hours, and minutes.

-t

The same as -p. This flag is provided for compatibility with last(1).

-w

--wide

Widen the duration field to show seconds as well as the default days, hours and minutes.

If multiple arguments are given, the logical OR operation between them is assumed, i.e., the information selected by each argument is printed. This, however, does not apply to the -c option. That option is always combined with the rest of command line by logical AND.

The pseudo-user ‘~reboot’ logs in on every reboot of the network access server.

If radlast is interrupted, it indicates to what date the search had progressed.
