LEARN ABOUT PLAN9
newuser
NEWUSER(8) System Manager's Manual NEWUSER(8) NAME
newuser - adding a new user SYNOPSIS
rc /sys/lib/newuser DESCRIPTION
To establish a new user on Plan 9, add the user's name to /adm/users by running the newuser command on the console of the file server (see users(6) and fs(8)). Next, give the user a password using the changeuser command on the console of the authentication server (see auth(8)). At this point, the user can bootstrap a terminal using the new name and password. The terminal will only get as far as running rc, however, as no profile exists for the user. The rc(1) script /sys/lib/newuser sets up a sensible environment for a new user of Plan 9. Once the terminal is running rc, type rc /sys/lib/newuser to build the necessary directories in /usr/$user and create a reasonable initial profile in /usr/$user/lib/profile. The script then runs the profile which, as its last step, brings up 81/2(1). At this point the user's environment is established and running. (There is no need to reboot.) It may be prudent at this point to run passwd(1) to change the password, depending on how the initial password was cho- sen. The profile built by /sys/lib/newuser looks like this: bind -a $home/bin/rc /bin bind -a $home/bin/$cputype /bin font = /lib/font/bit/pelm/euro.9.font switch($service){ case terminal prompt=('term% ' ' ') fn term%{ $* } exec 81/2 case cpu bind -b /mnt/term/mnt/81/2 /dev prompt=('cpu% ' ' ') echo -n $sysname > /dev/label fn cpu%{ $* } news case con prompt=('cpu% ' ' ') news } Sites may make changes to /sys/lib/newuser that reflect the properties of the local environment. Use the -c option of mail(1) to create a mailbox. SEE ALSO
