# jc.parsers.ls_s
jc - JSON CLI output utility `ls` and `vdir` command output streaming parser
Options supported:
- `lbaR1`
- `--time-style=full-iso`
Note: The `-1`, `-l`, or `-b` option of `ls` should be used to correctly parse filenames that include newline characters. Since `ls` does not encode newlines in filenames when outputting to a pipe it will cause `jc` to see multiple files instead of a single file if `-1`, `-l`, or `-b` is not used. Alternatively, `vdir` can be used, which is the same as running `ls -lb`.
The `epoch` calculated timestamp field is naive (i.e. based on the local time of the system the parser is run on)
The `epoch_utc` calculated timestamp field is timezone-aware and is only available if the timezone field is UTC.
Usage (cli):
$ ls | jc --ls-s
Usage (module):
import jc.parsers.ls_s
result = jc.parsers.ls_s.parse(ls_command_output) # result is an iterable object
for item in result:
# do something
