Problems with bash...

Dear Comunity:

I have recently installed Fedora 8 on my PC. When I try to use some commands of bash like LSMOD, MODPROBE, IFCONFIG, etc; It simpley doesn't work:

[Soren@localhost ~]$ lsmod
bash: lsmod: command not found
[Soren@localhost ~]$

It just works with su -:

[root@localhost ~]# lsmod

What is happen with bash? Do I need to stablish a change in a script or do a special procedure for having bash commands available in all users?

Any help I really appreciate it. Thanks in advance.

You would have to alter your .bash config files to add those commands to the users bash config. Those commands are usually reserved for the root user as most of them reside in /sbin. This would have to be added to the paths of the users you want to have access to those commands. This is definitely not a good idea on a multuser system to have /sbin commands available to regular users.

It won't really matter if you add the /sbin and /usr/sbin to a user path, but it's a bit pointless. For many of the commands, you won't be able to run them anyway unless you're root, since they require root privileges. And as far as security is concerned, normal users can generally still access them, they just have to specify a full path. It's not really a security feature, more a matter of convenience.

Many thanks for your suggestions, I think as a newbie and specially if you start with Ubuntu, the security issue is not important for a while, after gain some experience using Fedora.

I changed Ubuntu to Fedora, 'cos I found many problems with driver compatibility specially if you're using an atheros wireless board. In Ubuntu sbin commands are available for all users. Nonetheless Fedora is stronger and more flexible and It has lots of potential for doing your own drivers!!

When using commands like ifconfig as a regular user than add the full path to the application (/sbin/ifconfig). As already pointed out, for most commands you have to be root to apply changes, though in many cases it should be possible to get at least some diagnostic output as a regular user from these /sbin applications (ifconfig for example is helpful even without being root).
