Couple of bash questions

[Dave Mason]

renaming away extra .blah before final extension:
   mv "$i" "`echo X $i|sed 's/^X \([^.]*\).*\(\.[^.]*\)$/\1\2/'`"

the \. means use the . as a ..

resolving script problem:
.... "`basename $i .avi`.mp4"

The double quotes cause it to be treated as a single token.
