Last active April 23, 2024 15:08
Simple Email Validator in Bash
#!/usr/bin/env bash
#
# RFC standard of the email address could be found in rfc5322, rfc6854, etc.
#
# however, it is hard to escape all the special characters in the bash
# so, in this script, it will only check for the address syntax only
# having some valid/invalid inputs to test its result
#
# please be noted that, it is not design to detect mailbox deliverability
