NHS Number replacer CLI

National Health Service (NHS) Number replacer command line interface (CLI).

Steps

This program does these steps:

1. Read each line from standard input.

2. Match a regex pattern that is essentially "### ### ####".

3. Replace the match with a NHS Number that is a testable random sample i.e. in the NHS Number reserved range of "999 000 0000" to "999 999 9999".

4. Output each line to standard output.

Example

Run:

echo "111 111 1111" | nhs-number-replacer-cli

Output:

999 265 6328
