Explanation / Answer
Command for OS: cat/etc/os-release
Command for kernel number: uname -a
Command to know unix shell: echo “$$”
Command to know unix shell version: echo $SHELL.- -version
Command to find out Mac address: if config-a
Command to find out CPU information: $more/proc/cpuinfo or $cat/proc/cpuinfo or $less/proc/cpuinfo
For all these commands, you just need to do the same thing :-
1) Open terminal
In case of remote server login ; after opening terminal please use this command
ssh user@server-name
After this type your provided commands, it will work
For finding the absolute path to the executable vim in your $PATH ; then we can use "which"
Example :- which vim
Note :- You can also use whereis but it will show all path for vim files not necessarily executable
