How can I extract the group names from the id output?
 
Hello all,

I belong to these groups in my linux os.

Code:
$ id
uid=1000(davevlz) gid=1000(davevlz) groups=1000(davevlz),4(adm),24(cdrom),27(sudo),30(dip),46(plugdev),115(lpadmin),135(sambashare),999(vboxusers)
How can I extract the group names and use a comma as a delimiter to look like this below:

davevlz,davevlz,davevlz,adm,cdrom,sudo,dip,plugdev,lpadmin,sambashare,vboxusers

Thanks in advance

Use "groups" instead of "id"

If you then need to change delimiter from space, "tr" is probably the simplest option.

Code:
$ groups | tr " " ","
davevlz,adm,cdrom,sudo,dip,plugdev,lpadmin,sambashare,vboxusers
