Have a look at the following:

GNU's Bulletin, vol. 1 no. 6, January, 1989
Contents of Beta Test Tape
https://www.gnu.org/bulletins/bull6.html#SEC17

GNU's Bulletin, vol. 1 no. 7, June, 1989
https://www.gnu.org/bulletins/bull7.html
"A collection of utilities for file manipulation, including ls, mv, cp, 
cat, rm, du, head, tail and cmp will be released soon."
...
"The GNU project is working to provide reimplementations of System V 
features that Berkeley Unix lacks, such as improved shells and make 
commands."

GNU's Bulletin, vol. 1 no. 9, June 1990
https://www.gnu.org/bulletins/bull9.html#SEC10
GNU Project Status Report
"We have added a collection of utilities for file manipulation to the 
Pre-Release tape. The collection includes ls, mv, cp, cat, rm, du, head, 
tail, cmp, chmod, mkdir, and ln."

So around same time GNU project didn't publish some the most common 
tools, but soon did. I didn't check, but I am pretty sure these are all 
different code than the rewritten BSD code. Duplicated work.
