I think the proper solution is to ignore cdpath by changing the
construct to:
abs=`cd ./dir && pwd`
That is, use an absolute or relative path instead of just a directory
name. Farily typical usage would be:
abs=$(cd $(dirname $0)/foo && pwd)
(or, to avoid bashisms: here=`dirname $0`; abs=`cd "$here/foo" && pwd`)
which avoids the CDPATH problem entirely, since `dirname $0` will
resolve to at least ".".
