The POSIX standard command is newgrp - install cygwin-doc to see Cygwin (and 
newlib libc) man pages (and info, html, PDF docs), man-pages-posix to see POSIX 
man pages, and man-pages-linux if you want to see recent Linux release man pages.

To see possibly relevant commands, run:

$ apropos -s 1,1p group
chgrp (1)            - change group ownership
chgrp (1p)           - change the file group ownership
chown (1)            - change file owner and group
g3topbm (1)          - convert a Group 3 fax file into a PBM image
groups (1)           - print the groups a user is in
id (1)               - print real and effective user and group IDs
make (1)             - GNU Make utility to maintain groups of programs
make (1p)            - maintain, update, and regenerate groups of programs
mkgroup (1)          - Write /etc/group-like output to stdout
newgrp (1)           - change primary group for a command
newgrp (1p)          - change to a new group
pbmtog3 (1)          - convert a PBM image into a Group 3 MH fax file
