# jc.parsers.ls
jc - JSON CLI output utility ls Parser

Note: The -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 -l or -b is not used.

Usage:

    specify --ls as the first argument if the piped input is coming from ls

    ls options supported:

                    -lbaR
    --time-style=full-iso
                       -h  file sizes will be available in text form with -r but larger file sizes
                               with human readable suffixes will be converted to Null in default view
                               since the parser attempts to convert this field to an integer.

Compatibility:

    'linux', 'darwin', 'cygwin', 'aix', 'freebsd'

Examples:

    $ ls /usr/bin | jc --ls -p
