 # jc.parsers.ls
-jc - JSON CLI output utility ls Parser
+jc - JSON CLI output utility `ls` and `vdir` command output parser
 
-Usage:
+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 the default view since the parser attempts to convert this field to an integer.
 
-    specify --ls as the first argument if the piped input is coming from ls
+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. Alternatively, `vdir` can be used, which is the same as running `ls -lb`.
 
-    ls options supported:
-    - None
-    - la
-    - 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.
