That should be easy - if you write your email message on the same machine:

1. Start writing the mail message where you want to show us
   the error.
2. Mark the error text using the mouse.
   a. Put mouse cursor over the beginning of the text
   b. Hold down button one
   c. Drag along the text, you should see it getting selected
   d. release the mouse button
   Now, the message is highlighted
3. Put the mouse cursor over the email message, and press the
   third mouse button. This causes the highlighted error text
   to be copied into the email message.
   If your mouse doesn't have a third button, press the other
   two simultaneously instead.

This is how you copy just about any text from one app to another in
linux. The method is different from windows, but much quicker.

If you're writing your mail on another machine, paste the error messages 
into a file instead. Then transfer the file to where you write your mail.

Try the "ls" command. Is the file lilypond-2.14.0-1.linux-x86.sh there?
Maybe you mis-spelled it?

If the file isn't there, use the "cd" command to move to the correct 
directory first. Then use "ls" to check.  Web browsers tend to put files 
in a directory named "Downloads".

If the file is there, avoid mis-spelling by using tab completion. Type
something like:

sh lilypond-2.14

then press the TAB key. Linux should now fill out the rest of the 
filename so you don't have to. This saves time and avoids tyiping 
errors. It works provided that there is only one file where the name 
starts with "lilypond-2.14"

I don't think lilypond's midi output is capable of making arpeggio sound 
yet. So you can print scores with arpeggio symbols, but the midi won't 
do that.

To get arpeggio in midi, write the arpeggio out using ties.
Example:
http://lilypond.org/doc/v2.12/Documentation/user/lilypond/Writing-rhythms#Ties

Scroll down to "Using ties with arpeggios"


Something similiar can be done do get realistic guitar sound. A 
guitarist doesn't normally hit all the strings at the same time, but the 
lilypond midi guitar do...
