I'm not sure how important portability is here, but if you are on a
linux system then /bin/sh is linked to /bin/bash. In bash you can do
this as:
oldmonth='07'
echo ${oldmonth#'0'}
The ${A#B} construct removes the shortest part of pattern B from the
front of $A (and ${A##B} removes the longest part).
This has to have lower overhead than the calls to sed that others have
been posting. :-)
