# purity-ng(6)

general purpose purity testing software

## NAME

purity-ng - general purpose purity testing software

## SYNOPSIS

**purity-ng** \[*OPTION*\]... list\|*FILE*\|*TESTNAME*

## DESCRIPTION

Purity is an interactive purity test program with a simple, user interface and datafile format. For each test, questions are printed to the your terminal, and you are prompted for an answer to the current question. At a prompt, these are your choices:

-

  ```
  y      Answer "yes" to the question.
  n      Answer "no" to the question.
  b      Backup  one  question, if you answered it incorrectly, or someone is watching you take the test, and you don't (or do) want to admit a different answer.
  s      Print your current score on the test you are taking.
  q      Quit the test, and print the current score.
  ?      Print a help screen for the current prompt.
  ```

At the end of the test, your score is printed out. For most purity tests, lower scores denote more "experience" of the test material.

## OPTIONS

- **--version**

  print current version of **purity-ng**

- **-h, --help**

  show the help message and exit

- **-p**

  print the test without prompting for answers.

- **-r**

To get a list of all purity tests available globally on your system, run `purity-ng list`.
