I used this handy little feature I have in KDE called "Find Files/Folders" which is equivalent to the "Search" in Windows and found both of them in /sbin.
I have heard in the past that in Red Hat distros you need to switch user with "su-" or "su -" to get full root permission.

Commands like ifconfig and fdisk have to be executed as root.
So you have to do the following:
$ su -
Password: Enter your password
# Now you are root and can use ifconfig and those commands.

By the way if you are trying to become root just by typing "su" you wont be able to use those commands, because you dont have the complete root PATH.

You have to be fully root. but with a su then do /sbin/ifconfig and see if that works.

That is so true. It through me off the first time I installed and tried to run ifconfig. I was like why does root not have access to sbin. Then I did a su - and it worked perfectly. so in short you do have to take on full root permissions or use the full path to the command.

if you don't include the "-" with the su command your environment (PATH) does not get updated and the system will not be able to locate those command binaries, as mentioned above.

I never issue su without including the hyphen. it's sorta pointless.

bachelorlko,

Some command line tools you can try are which and locate here is what it looks like on one of my systems:

Code:

$ su -
Password: 
[root@whisper ~]# which ifconfig
/sbin/ifconfig
[root@whisper ~]# locate ifconfig
/sbin/ifconfig
/usr/share/man/de/man8/ifconfig.8.gz
/usr/share/man/fr/man8/ifconfig.8.gz
/usr/share/man/man8/ifconfig.8.gz
/usr/share/man/pt/man8/ifconfig.8.gz
/usr/share/zsh/4.3.4/functions/_ifconfig
[root@whisper ~]#

When you swich user to root, make sure you use the - as this tells swich user to transfer root's full path.

Hope this helps,
~Art

You can also try whereis command. Just open command shell and type in
> whereis ifconfig

and you will get the location of the file as a reply.

Thanks everybody for overwhelming response,i have found out the Fdisk and the other commands in /sbin and have updated the PATH ,it's working fine.
Thanks Once again
