Usage

From source file:org.apache.atlas.utils.AuthenticationUtil.java

/**
 * If the initial password is:/* w ww  . j  a  v  a2 s. c o  m*/
 * '*' - replace it with a line read from the system console
 * '-' - replace it with next line from STDIN
 * 'ABCD' - if the input is all upper case, use the field as an environment variable name
 *
 * Note: there are no guarantees that the password cannot be snooped.
 *
 * Even using the console may be subject to memory snooping,
 * however it should be safer than the other methods.
 *
 * STDIN may require creating a temporary file which could be read by others
 * Environment variables may be visible by using PS
