| 20 | .SH NAME | |
| 21 | adduser \- procedure for adding new users | |
| 22 | .SH DESCRIPTION | |
| 23 | A new user must choose a login name, which must not already appear in | |
| b3e3a15e KB |
24 | .IR /etc/passwd or |
| 25 | .IR /usr/lib/aliases . | |
| 26 | It must also not begin with the hyphen (``-'') character. | |
| 27 | It is strongly recommended that it be all lower-case, and not contain | |
| 28 | the dot (``.'') character, as that tends to confuse mailers. | |
| 29 | An account can be added by editing a line into the passwd file; this | |
| 30 | must be done with the password file locked e.g. by using | |
| 0de23b92 KB |
31 | .IR chpass (1) |
| 32 | or | |
| 902f6982 KM |
33 | .IR vipw (8). |

| 35 | A new user is given a group and user id. | |
| b3e3a15e KB |
36 | Login's and user id's should be unique across the system, and often across |
| 37 | a group of systems, since they are used to control file access. | |
| 0de23b92 | 38 | Typically, users working on similar projects will be put in the same groups. |
| b3e3a15e KB |
39 | At the University of California, Berkeley, we have groups for system staff, |
| 40 | faculty, graduate students, and special groups for large projects. | |

| 0de23b92 | 42 | A skeletal account for a new user \*(lqernie\*(rq might look like: |
| 902f6982 | 43 | .IP |
| b3e3a15e | 44 | ernie::25:30::0:0:Ernie Kovacs,508 Evans Hall,x7925,642-8202:/a/users/ernie:/bin/csh |
| 902f6982 | 45 | .PP |
| 0de23b92 KB |
46 | For a description of each of these fields, see |
| 47 | .IR passwd (5). | |
| 902f6982 KM |
48 | .PP |
| 49 | It is useful to give new users some help in getting started, supplying | |
| 50 | them with a few skeletal files such as | |
| 51 | .I \&.profile | |
| 52 | if they use \*(lq/bin/sh\*(rq, or | |
| 53 | .I \&.cshrc | |
| 54 | and | |
| 55 | .I \&.login | |
| 56 | if they use \*(lq/bin/csh\*(rq. | |
| 57 | The directory | |
| 58 | \*(lq/usr/skel\*(rq contains skeletal definitions of such files. | |
| 59 | New users should be given copies of these files which, for instance, | |
| 0de23b92 | 60 | use |
| 902f6982 KM |
61 | .IR tset (1) |
| 62 | automatically at each login. | |
| 63 | .SH FILES | |
| 64 | .ta 2i | |
| 0de23b92 | 65 | /etc/master.passwd user database |
| 902f6982 KM |

| 0de23b92 | 71 | User information should (and eventually will) be stored elsewhere. |
