A Linux shell script to rename files with a counter and copy them

As a brief note today, I was recently looking for all Messages/iMessage files that are stored on my Mac, and I used this shell script to copy all of those files — many of which have the same name — into a directory named tmpdir, giving them all new names during the copy process:

    fname=`basename $i`
    cp $i tmpdir/${count}-${fname}
    count=`expr $count + 1`

How to get MacOS Message app to sync up with iPhone messages (get it to update)

A JavaMail POP reader example (pop3 reader)

While working on a Java application, I found the need for a simple Java mailbox reader. I wanted to be able to scan through one of my POP/POP3 mailboxes for messages, and then do something with those messages.

To that end I created the following example JavaMail POP mailbox reader. It connects to a standard POP/POP3 mailbox, then scans through all the messages in the "Inbox" folder.

Jumping right to the solution, here's the complete source code for a JavaMail example class that demonstrates how to search for unseen (unread) email messages in a POP/POP3 mailbox:
