Elf OS 0.3.2 (requires kernel 0.3.2)                    

• cal [month year]                     calendar  program. See https://github.com/mecparts/Elf-Elfos-cal
• chmod +x filename                sets  execute flag for a binary
• chmod -x filename.                removes execute flag for a binary
• chmod +h filename                hides file
• chmod -h filename                 makes file visible
• chmod +w filename               makes file writable
• chmod -w filename                makes file read only
• date mm/dd/year hh:mm:ss   sets the date and the RTC
• himem [address]                    displays the first available upper address or resets hi memory address
• hydro                                      IDE accelerator See https://github.com/dmadole/
• nitro                                        loads soft UART accelerator plug-in - (runs at 19.2 Kbps) See https://github.com/dmadole/
• sys filename (kernel)              used to update kernel to the one in the filename chosen.
• touch filename                       sets time and date on a file if RTC present. If no RTC present,  sets date.
• turbo [-k]                               loads file accelerator plug-in [use -k option for kernel space]  https://github.com/dmadole/
• xr  filename                           XMODEM receive file transfer using software UART. If running nitro use yr instead of xr. 
• xrb filename                          XMODEM receive file transfer using hardware UART (runs 19.2 Kbps)
• xs filename                            XMODEM send file transfer using software UART 
• xsb filename                          XMODEM send file transfer using hardware UART (runs 19.2 Kbps) See https://github.com/fourstix/Elfos-utils        
• yr  filename                           YMODEM receive file transfer using software UART. Many files can be received at once. NOTE: yr requires nitro to run. See:   https://github.com/dmadole/ 
• INIT [ INIT.rc]                         At boot time, runs commands  from text file INIT.rc  for binary files located  in  / or /BIN. After system boot, can be used  as a primitive batch processor.  See https://github.com/dmadole/

dir takes the following options, all optional: 

-d  Sort list by date and time

-l  Long listing, one file per line with dates and sizes

-n  Sort list by name, low to high

-s  Sort list by size, low to high

-r  Reverse order of sort
