My account has been created on a LINUX machine. But, I don't know which type of user I am ( root user or normal user) and which type of access I have. Is there any command through which I can check whether I have sudo access or not in a linux machine if I already have an account.
sudo -l to determine what level of capabilities you have assigned within its configuration.
man 8 sudo
-l[l] [command] If no command is specified, the -l (list) option will list the allowed (and forbidden) commands for the invoking user (or the user specified by the -U option) on the current host. If a command is specified and is permitted by the security policy, the fully-qualified path to the command is displayed along with any command line arguments. If command is specified but not allowed, sudo will exit with a status value of 1. If the -l option is specified with an l argument (i.e. -ll), or if -l is specified multiple times, a longer list format is used.
To see which groups you are part of try
groups. Whether or not you have access to
sudo depends on your local configuration.
If when running
groups you don't see
staff or a group specifically set up fir
sudo access then you likely haven't been automatically granted
sudo-ing rights. Note that those can be added via the
sudo configuration as well.
