Here’s a command I use all the time
useradd -d /home/kevin -s /bin/bash -m kevin

This adds a user ‘kevin’, makes the home directory and sets the default shell to bash.

I can’t ever remember the syntax, so here’s a link -> https://www.aplacetocode.com/tutorials/first-time-server-tutorial/

Otto: You can either set an email alias (mail to “otto” goes to “xpto”) using the methods for your MTA, which will just send mail sent to one account to the other, or you can create two accounts with the same UID and home directory.

Is is possible to create something like a symlink for a user? Like to be able to reference a user my more than a name? Example: ‘otto’ and ‘xpto’ are the same user.

Thanks.

As reported in Rhel 4 – adduser & useradd are same. Similarly /etc/skel files are not copied . How to overcome this.

@Renich, I agree that "marge" is not a secure password. I've updated the article with reference to the article I wrote earlier about password best practices. I've also updated the homer-family.txt file with relatively stronger password. Thanks for your feedback. @Tapas, The comment field is not supposed to truncate anything automatically. Can you please do one of the following and I'll research about this further: - Reply to the email I sent you with the words that you typed in the comment section that got wiped out. - Try to enter the comment again. But this time, make sure you put those between

@Hans, That is a copy/paste mistake. Thanks for pointing it out. I've corrected it. @Vinodh, On a very high level, following is the command. I'll try to write a detailed post later on this topic.

Encrypt: gpg --encrypt Recipient [Data]

Decrypt: gpg [--decrypt] [Data]

@Daniel, Thanks for your comment. I'm glad you found this article very helpful. @Flynets, Thanks for sharing the scripts your wrote to add many users. It looks great.

hi, a few years later i write a little shell script for create many users with same configuration using useradd in 2 variants:

for debian-like: http://snippets.dzone.com/posts/show/4980
for red-hat-like: http://snippets.dzone.com/posts/show/4979

the only differerence is the command (gpw/passwdgen) for generate random password.
it take 2 arguments:
1- name of file that contains usernames (it’s better one per line)
2- name of the log where will be write the couple username-password.

instead for blocking the users you ca use http://snippets.dzone.com/posts/show/5191

bye

Sry, but isn’t the 1009 of bart in conflict with the uid of marge?
marge:marge:1009:1000:Marge Simpson:/home/marge:/bin/csh
bart:bart:1009:1000:Bart Simpson:/home/bart:/bin/ksh
