bash and "groups" command please help

[beerstein]

Hi: I have TLC 3.8.4 and 4.7.7 running. The terminal CL responds to:
$ groups
with:
bash: groups: command not found
tc@box:~$

bash is installed. $ help groups
also does not work.

$ help echo
works although it is also a bash command.
$ which and whereis also

How can I make the "groups" command work?

Thank you for your help

Use “busybox id -Gn” instead ;-)
