Built-in ls?

I think there is a (pretty obscure) form of ls, i.e., directorylisting,built into q but I can’t find it anymore. Did I imagine it? If so,I’ll justuse system.Thanks

key`:.

For host OS?directory?listing see?

This is platform specific.?

fileList: value “\dir /B” ?/ on Windows

fileList: value “\ls” ?/ on Linux?

/abbat

Thanks. It’s key I was looking for; \ls and \dir are not Q built-ins,just special cases of \some_os_cmd
