I install RHEL,
when i try to use apt-get, It says command not found. Did I installed RHEL in wrong way or do I need to configure any file. Please, help me.

Welcome to the forums!

I'd recommend using yum rather than trying to use apt on RHEL:

In addition to what ozar posted, apt-get is mostly for Debian based systems and it's derivatives such as Ubuntu, Linux Mint and others and not rpm based systems like RHEL, Fedora and CentOS in addition to a few other rpm based systems.

Even yum, iostat,tcpdump,iptraf are not working. saying these commands are not found

[MikeTbob]

Have you tried these commands as root user or preface each command with kdesu or perhaps it's now kdesudo for KDE, and gksu or gksudo for Gnome, you'll need the root password.

Try gaining root permissions with the su command, then try yum again:

su

...or

su -

... then

yum install name_of_package

...assuming that yum itself is installed.

You should use su - for Administrative commands.
su and su - provide different level of privileges.

Execute this

su 
echo $PATH
exit
su -
echo $PATH

Notice the difference in PATH .

For Administrative commands, use su -. Its su and hyphen ( minus sign ).

Note also that you can go to a terminal and check the manual page for su to get more options on using the su command:

man su

Report back if you are still having problems.

use root as

# yum search iostat

#yum search tcpdump

#yum search iptra

for search for these command providing rpm packages


and then use

yum install command
