Root Check
While trying to add a script which would install tmate
, but for me to be able to put executables under bin
folder would require a root permission. So, before trying to put the executables in the bin
, permission check was a must. Though, checking if running as root isn't that hard using whoami
command.
I would've used this approach, but as an answer on StackOverFlow stated
"As a warning, do not check if a user is root by using the root username. Nothing guarantees that the user with ID 0 is called
root
. It's a very strong convention that is broadly followed but anybody could rename the superuser another name."
which I think does makes sense. So, that's why the other way around do the same is to check EUID variable, which is, in fact, read-only variable initialized at shell start-up.
Which pretty much worked for me the way I intended it to.
