How to process email attachments on linux
I will share my experience that I had get through while trying to find a way to process an attachment from my personal email using Linux bash scripting.
To start with the story I purchased a daily proxy feed from Hidemy*** which I wanted to feed to our proxy software E-bouncer. The down side is that Hidemy*** will only send you the list as an attachment on your purchased email address which is my personal email. I had to extract the list from a zip file and upload it to the server on daily basis you can imagine how boring was that.
So I thought why don’t I automate the entire process and the plan was to create a filter on my gmail service to forward any email with attachment that comes from Hidemy*** to a custom email that is accessed within the server which is “hproxy a@t oman0.net”. If the email is received on my inbox and the condition is met it will straight forward it to the custom email address.
Therefore I had to write a tiny shell script that would process the “hproxy a@t oman0.net” email address and extract the attachment then copy the new arrived proxy list to E-Bouncer directory so when users retrieves proxy list they get the most recent one automatically.
Here is the script that does the job in case you run into similar situation:
First you will need to install uudeview
wget http://springdale.math.ias.edu/data/puias/6/x86_64/os/Addons/uudeview-0.5.20-19.puias6.x86_64.rpm rpm -Uvh uudeview-0.5.20-19.puias6.x86_64.rpm yum install uudeview
