# The following command has 3 parts:
|
|
#
|
|
# 1. Run `sudo` with `-v`. Does the following:
|
|
# • with privilege: asks for a password immediately.
|
|
# • without privilege: exits with error code 1 and prints the message:
|
|
# Sorry, user <username> may not run sudo on <hostname>
|
|
#
|
|
# 2. Pass `-n` to `sudo` to tell it to not ask for a password. If the
|
|
# password is not required, the command will finish with exit code 0.
|
|
# If one is required, sudo will exit with error code 1 and print the
|
|
# message:
|
|
# sudo: a password is required
|
|
#
|
|
# 3. Check for the words "may not run sudo" in the output to really tell
|
|
# whether the user has privileges or not. For that we have to make sure
|
|
# to run `sudo` in the default locale (with `LANG=`) so that the message
|
|
# stays consistent regardless of the user's locale.
