Shell script debug (Fwd)

Matt must've hit 'r' instead of 'g' and sent this only to me.

A very handy thing to do when debugging bash scripts is to put "set -x" at 
the
top of the script.  This will give you feedback.  LOTS of feedback.  Of
course, sometimes it's completely useless, but that's what happens in
debugging.

If you're making a script with a DOS editor and the lines end with \r\n
instead of \n , bash will be very unhappy.  "dos2unix" can take care of 
that.

Also, did you know about the -p option to mkdir?  Using that, I can do
something like "mkdir -p ~/temp/wibble/foo" instead of "mkdir ~/temp ; 
mkdir
~/temp/wibble ; mkdir ~/temp/wibble/foo".
