How to set permissions for multiple groups on a file under Linux

Information for the file to be set:

v0id6@v0id6-eof ~ $ ls Testacl-la

-rw-rw-r--+ 1 v0id6 v0id6 9 March 2 14:21 testacl

Gets the access control list for the file (this is the value before the SETFACL setting is used)

v0id6@v0id6-eof ~ $ getfacl Testacl

# File:testacl

# OWNER:V0ID6

# GROUP:V0ID6

user::rw-

group::r--

other::r--

Configure permissions for multiple groups to read and write

v0id6@v0id6-eof ~ $ setfacl-m G:V0ID6:RW,G:YYGYDJTEST:RW Testacl

v0id6@v0id6-eof ~ $ getfacl Testacl

# File:testacl

# OWNER:V0ID6

# GROUP:V0ID6

user::rw-

group::r--

group:v0id6:rw-

group:yygydjtest:rw-

mask::rw-

other::r--

Remove Group Control permissions

v0id6@v0id6-eof ~ $ setfacl-x g:yygydjtest Testacl

v0id6@v0id6-eof ~ $ getfacl Testacl

# File:testacl

# OWNER:V0ID6

# GROUP:V0ID6

user::rw-

group::r--

group:v0id6:rw-

mask::rw-

other::r--

Note: For the acquisition and configuration of group names use Cat/etc/group to view existing groupings or use Groupadd to add them
