# jc.parsers.last
|
|
|
|
jc - JSON Convert `last` and `lastb` command output parser
|
|
|
|
Supports `-w`, `-F`, and `-x` options.
|
|
|
|
Calculated epoch time fields are naive (i.e. based on the local time of the
|
|
system the parser is run on) since there is no timezone information in the
|
|
`last` command output.
|
|
|
|
Usage (cli):
|
|
|
|
$ last | jc --last
|
|
|
|
or
|
|
|
|
$ jc last
|
|
|
|
Usage (module):
|
|
|
|
import jc
|
|
result = jc.parse('last', last_command_output)
|
|
|
|
