I received a file via e-mail, but it wasn't an attachment. Now what?

In some e-mail systems, files are sent through e-mail in a form known as uuencoded. This basically takes the binary data of a file and changes it into ASCII text, thus allowing it to be send effortlessly through an e-mail.

UUencoded files usually start with something similar to this:
begin 600 somefile.bin

To decode a uuenoded file from your e-mail, you must save it and use the uudecode program. If you are using PINE, this would be accomplished by going to the letter containing the e-mail containing the uuencoded information. Next, export the e-mail using the (E)xport option. After exporting the file, quit PINE and drop to the command line. Type "uudecode filename" where filename represents the name you gave to the e-mail you exported. This will reassemble the file into its original form, using the original name (unless otherwise specified*).

Summary (UNIX)

1. Export e-mail to a file
2. Quit mail program and drop to UNIX shell
3. At command line type "uudecode filename"

* Various options, including extrication to the name of your choice, can be found by typing "man uudecode" at the UNIX command line. UUdecoders for Macintosh, Windows, and most other platforms are available.
