would advise if I would like to change group from sis1 to sis2 , the getfacl result should be as below , what can I do ? thanks

setfacl is used to modify ACLs.

sag47 is right, you have to use setfacl command to modify ACL. You might want to have a look at this: https://access.redhat.com/documentat...s-setting.html

I tried setfacl -m , but it only add the entry but not modify the entry , what advise how to do it ? thanks

It should be something like:

This will set acl on the given directory for sis1 group to be null that is no read, no write and no execute (this will only do it for top level, if you want to do it recursively that is for sub-directories using -R, check setfacl man page)

Next:

Again if you want to do it recursively use -R.

thanks reply
I tried the below method
it will ADD entry g:sis2:--- , but not MODIFY the existing entry ( from sis1 changed to sis2 ) , would advise how to do the MODIFY ?

Thanks
