In many Unix variants, "nobody" is the conventional name of a user identifier which owns no files, is in no privileged groups, and has no abilities except those which every other user has. It is normally not enabled as a user account, i.e. has no home directory or login credentials assigned. Some systems also define an equivalent group "nogroup".
Many system administrators allocate for each user also a personal primary group that has the same name as the user's login name, and often also has the same numeric GID as the user's UID. Such personal groups have no other members and make collaboration with other users in shared directories easier, by allowing users to habitually work with ...
This results in users being prompted to select whether they want to boot into Mac OS or Linux when the machine starts. [8] By 2008, a number of major Linux distributions had official versions compatible with Mac PowerPC processors, including: [8] Gentoo [8] Debian [8] (until Debian 8 [10]) Ubuntu [8] (until Ubuntu 16.10 [11] [12])
While UBPorts tried to follow suit with Ubuntu Touch, a wider development of free Linux operating systems specifically for mobile devices was only really spurred in the latter 2010s, when various smaller companies started projects to develop open source phones.
Save yourself time when sending the same email to multiple people by creating a group of your contacts.

The wheel group is a special user group used on some Unix systems, mostly BSD systems, [citation needed] to control access to the su [4] [5] or sudo command, which allows a user to masquerade as another user (usually the super user). [1] [2] [6] Debian and its derivatives create a group called sudo with purpose similar to that of a wheel group. [7]
Since getent uses the same name service as the system, getent will show all information, including that gained from network information sources such as LDAP. The databases it searches in are: ahosts, ahostsv4, ahostsv6, aliases, ethers (Ethernet addresses), group, gshadow, hosts, netgroup, networks, passwd, protocols, rpc, services, and shadow.
All contain important data such as user names, IP addresses, application names, etc. This way an event can be represented as a list of key-value pairs which we call a "field". The name of the field is the key and the field data is the value. In another terminology this meta-data is sometimes referred to as event property or message tag.
