while i am typing w command in my linux server
getting this message
-bash: w: command not found

Either it's not in your $PATH or you deleted/uninstalled it.

I have run this command
$ yum whatprovides '*bin/w'
i got the same.
procps-ng-3.3.10-3.el7.i686 : System and process monitoring utilities
Repo : base
Matched from:
Filename : /usr/bin/w

procps-ng-3.3.10-3.el7.x86_64 : System and process monitoring utilities
Repo : base
Matched from:
Filename : /usr/bin/w

So what does return?

I have run this

stat /usr/bin/w; rpm -Vv procps-ng
stat: cannot stat `/usr/bin/w': No such file or directory
package procps-ng is not installed

Then install it...

yum install procps-ng

you have a MAJOR PROBLEM!!! - yes bold and caps!!!
you are running RHEL6
BUT the rpm you want to install is for RHEL7 -- see the problem
"procps-ng-3.3.10-3.el7.i686 "

that "el7" in the name


you can not install a rhel7 rpm on rhel6

if one of the repos you installed is for 7 that will cause MAJOR problems

also i see you have
base
extras
atomic
rpmforge

all installed but you did not install and configure "yum-priories" to keep the third party repos from REPLACING system files with DIFFERENT versions that might be INCOMPATIBLE with the RHEL base and updates


not installing and CONFIGURING that plugin might cause problems


also seeing as the "whatprovides" command is telling you to install a RHEL7 package on RHEL6
-- you have a bit of a problem

please post the output of
and if this outputs a list
please ALSO post it
that line will list ant INSTALLED rhel7 rpms on your rhel6 server

I have a two servers one is Redhat 6 and cent os 5 presently i have run given commands in cent os5

RHEL / CentOS 6 package is called "procps". The "-ng" part works for Fedora >= 16 / CentOS 7.

You make helping you really hard. Can you please stay with the server you have problems with? What do you think where you need to run the commands suggested by others? Of course on the RH 6 machine.

Please answer John's post if you want him (or others) to continue helping you.

you CAN NOT run the commands on RHEL5 to see if you messed up the rhel6 server with rhel7 packages ???

WHERE DID you go to school ?????
we need to tell people to AVOID that school like THE PLAGUE!!!!!
