I tried to switch to 'root' in CentOS by running
su. It does change to 'root', but it doesn't seem to be a real 'root' user.
For example, by default,
ifconfig command in
/sbin is not found in the path for a normal user, but for 'root', the command can be found. When I run
su, I still get
bash: ifconfig: command not found output when I try to run
However, when I run
ifconfig just works.
What is the difference between
su - in CentOS?
