Listmates,

        I'm stumped on another simple BASH problem. How do I read the last line 
of a
file with a while loop without requiring a blank line at the end of the file?
Simple example I'm stuck on:

{ while read alias url; do
        echo -e "${alias}\t${url}"
done } < ~/linux/scripts/config/repos

        The repos flat text file (shown with --- above and below to show no 
blank line
at the end) is:

---
<snip: other repos>
database        
http://download.opensuse.org/repositories/server:/database/openSUSE_10.3/
oss             
http://download.opensuse.org/repositories/openSUSE:10.3/standard/
oss-src         
http://download.opensuse.org/distribution/10.3/repo/src-oss/suse/
lastline        temp-last_line_test
---

        If there is no blank line at the end of the file, the while loop reads 
the
"oss-src" line, but does not read the "lastline". If there is a blank line at
the end, it reads "lastline" just fine. What is the trick to be able to read
the last line of the repos file regardless of whether there is a blank at the
end or not?
