I installed CentOS 5.5 on my VMWare 8 recently and I am trying to add a new user on the system. I am unable to add the user unless I use su - option. I believe it has to do something with path not set properly.

I updated the path and here is what it looks like /usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/bin:/usr/bin:/bin:/usr/X11R6/bin:/home/uone/bin:/sbin

I believe the command is in /sbin dir which is already a part of path. Can anyone suggest me what else I might be missing?

Try adding /usr/sbin to your path.

For example to add it to the end of the path you would do something like this:

export PATH=$PATH:/the/file/path

  • Yep! That did the trick, Added it as priority location in path. Thanks mdpc :)

    How would I do that? There is already a PATH = something in my .bash_profile? How do i add another one?

I know the OP answer was solved, however for those who are running CentOS from within the docker container, which appears to be missing both adduser and useradd, the solution is to install shadow-utils (under root obviously):

yum install shadow-utils
  • I am on Rocky Linux 8. I used to be able to use "addgroup" and "adduser" then after a few automatic updates addgroup is missing, and i checked /usr/sbin/adduser, it's linked to 'useradd'. My understanding was that useradd is different than adduser, adduser is more advanced and do more things for you.

/usr/sbin/useradd username -g groupname -d homedirectory
  • Its giving me error -bash: /usr/sbin/useradd: No such file or directory

  • you first need to install shadow-utils package and then use the /usr/sbin/useradd command. It should work this way. Maybe you did not install the shadow-utils in the first place. Commented Apr 7, 2023 at 6:27
whereis useradd

this is used to solve that problem

  • That only tries to find useradd, not install it.
