# jc.parsers.ls_s # jc.parsers.ls_s
jc - JSON CLI output utility `ls` and `vdir` command output streaming parser jc - JSON CLI output utility `ls` and `vdir` command output streaming parser
Options supported: This streaming parser requires the `-l` option to be used on `ls`. If there are newline characters in the filename, then make sure to use the `-b` option on `ls`.
- `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 `jc` `-q` option can be used to ignore parsing errors. (e.g. filenames with newline characters, but `-b` was not used)
The `epoch` calculated timestamp field is naive (i.e. based on the local time of the system the parser is run on) The `epoch` calculated timestamp field is naive (i.e. based on the local time of the system the parser is run on)
