text: Title: Make recursive options consistent in the filesystem shell
  Body: **Is your feature request related to a problem? Please describe.**
  
  We should try to make the usage and options in our filesystems shell mirror the most commonly used commands. For this issue I'm specifically requesting that options dealing with recursive operations are consistent with the most common bash/Posix implementations.
  
  Examples:
  
  - [cp](http://man7.org/linux/man-pages/man1/cp.1.html) can use `-r`, `-R`, or `--recursive`
  - [rm](http://man7.org/linux/man-pages/man1/rm.1.html) is the same as cp
  - [scp](https://linux.die.net/man/1/scp) only supports `-r`
  - [ls](http://man7.org/linux/man-pages/man1/ls.1.html) `-R` or `--recursive` (`-r` is taken by `--reverse` sorting flag)
  - [chmod](https://linux.die.net/man/1/chmod) `-R` or `--recursive`. There is no conflict with another `-r` option. It just doesn't take the lowercase flag.
  
  
  **Describe the solution you'd like**
  
  Most of our commands only use the `-R` flag to mark an operation as recursive. It would be nice if 
  we supported all variants that our standard bash commands support.
  
  
  **Describe alternatives you've considered**
  None as of now
