Email Validation Help with command line usage in Ubuntu


I've been searching for a while now for an optimal way to clean up a list of emails and came across two sources that to me seem to provide the best possible solution.


I chose to try the second one but I'm not quite sure how to use this script on the command line. I run Ubuntu through virtual box and I need some help with how I would run this scrip.

I saved the script (#2) in a local directory as emailvalidator.php and have another file with emails called emailcheck.txt.

What command would I need to use to call this script in the gnome terminal? Thank you in advance

If you are searching for a tool in gnome-terminal.
Then I better suggest you to use the power of regular expression from tools like grep/sed/awk.
Eg: if  you have a list of email addresses in a file(one in each line), you can run the following commands to filter the valid ones only.
cat file | grep -P '[a-zA-Z][a-zA-Z0-9\._-]+@[a-zA-Z0-9][a-zA-Z0-9\.]+'

[Note: this is just a quick solution and need some more tweak to perform flawlessly.]

Or if its possible can you share a chunk from your source (can be modified as well), and we can give you a full fledged solution.
Those scripts that you found are useful for php based online solution.
If you want to read about perl based regular expression:

Thanks for the responses.

- Ray, how would I run this script on the command line in unix?
Sorry - I do not know.  I do not use the command line; I use PHP scripts.  Since this was posted in the PHP zone I could only help with a PHP script.  Maybe one of the other experts could show you how to adapt it to command-line execution.  I am sure it is possible.
If you want to execute those php scripts, run:
$ php /path/to/file.php
@faithless1, Its not fair. The answer you accepted doesn't answer your question. Its just a simpler version of what you obtained yourself in #2.
My last 2 posts are directly answering your question.
