apply check on hostname command

[kashifr]

How to prevent administrator accidentally type “hostname –a”, which will change the hostname to –a. Normally this is happened when user confuse “uname” command with “hostname”. Any permanent solution to avoid this?

Hi,

# chmod -x /usr/bin/hostname
or rename the binary and write a wrapper script.

Rename the binary.

That being said, generally administrators with root privileges would know the difference between "hostname" and "uname" and not make the mistake. Also, if the mistake is made, it can very quickly be changed back.

I completely agree with Coolmar here. If an administrator has to be restricted from using a command, he shouldn't be an administrator in the first place.

By changing the bin file, it works fine.
