Name
whoami — stdin stdout - file -- opt --help --version
Synopsis
whoami
The whoami command prints the
name of the current, effective user. This may differ from your login
name (the output of logname) if
you’ve used the sudo command. The
following example distinguishes whoami from logname. In normal situations, they both
print your username:
➜lognamesmith ➜whoamismith
When you become the root user via sudo, then effectively you are the root
user, and whoami indicates
this:
➜sudo lognamesmith ➜sudo whoamiroot
