Administration - Linux Reference

Here are some solutions to problems Linux users often encounter. If you have a better solution or
have a question please send your solutions, questions, or comments to us.
Are any of these solutions obsolete? Are they clear and easy to understand?


useradd notes:
1. Login as 'root' and run groupadd to create a new group
   groupadd -g 567  'emailUsers'
   include the single quotes.

2. Now run useradd to add new user to newly created group.

For RedHat:
 useradd -c "Linux user" -d /home/users/tux -g 567 -m -s /bin/bash -r tux
For SuSE:
 useradd -c "Linux user" -d /home/users/tux -g 567 -m -s /bin/bash tux
For Slackware:
 just run adduser. This asks you a series of questions to create new user.

 Details:
  -c "Linux user" is the username
  -d /home/users/tux is the home user of 'tux'
       a directory /home/user/tux/ will be created with files inside
       of /home/user/tux/
  -g 567 is the group you just created
  -s /bin/bash is the shell this user will use
  tux is the username
3. Now change newuser's passwd for the first time
  passwd tux
