perl script to check the mail ids in the correct format or not

Shell Programming and Scripting
1

Hi Folks,

I have few mailids in a text file and need to check whether the mailid is in correct format or not.

If just to check whether the string is a mailid or not there is a perl module Email::Valid to do the business or we can implement our own logic.

But the mail_ids I am having is like

stephen.albert@xyz.com
ram.kiran@xyz.com
george.fish@xyz.com

The syntax will be firstname.lastname@xyz.com

I am looking for a perl expression/code to check whether the email id is in the above format or not.

What's wrong with Email::Valid module?

thought that it is not possible but I had done that using Email::Valid module. thanks...

and I do have a doubt.. I use padre IDE for developing perl scripts and I install the modules based on requirement directly in padre IDE which is just a button click...

I was trying to install Image::Grab module but I am getting an error message( attached the command prompt error message and log file).

Could you please check build.log (attached) and let me know what went wrong ?

Thanks in advance...

It could be possible that padre IDE is not installing the modules that are a pre-requisite for Image::Grab module.

From the screenshot, I understand that you're working on windows. I presume you've installed the Activestate flavour of perl. If that be the case, Activestate perl also provides a "Perl Package Manager". Installing modules using Perl Package Manager is again, as you mentioned "just a button click". Plus it also installs all the pre-requisites.
