 sudo -H -u otheruser bash -c 'echo "I am $USER, with uid $UID"' 
 

 -H   The -H (HOME) option requests that the security policy set
     the HOME environment variable to the home directory of the
     target user (root by default) as specified by the password
     database.  Depending on the policy, this may be the default
     behavior.
 

 -u user     The -u (user) option causes sudo to run the specified
      command as a user other than root.  To specify a uid
      instead of a user name, use #uid.  When running commands as
      a uid, many shells require that the '#' be escaped with a
      backslash ('\').  Security policies may restrict uids to
      those listed in the password database.  The sudoers policy
      allows uids that are not in the password database as long
      as the targetpw option is not set.  Other security policies
      may not support this.
