bash option cdspell

["K. John Wu" <kw...@lbl.gov>]

Just thought someone else might encounter the same problem.  If your 
initialization file for bash has the option cdspell set, such as 
through the following command

shopt -s cdspell

then the bin directory may not be set correctly in the shell script 
that set bin through the following command

bin=`cd "$bin"; pwd`

An alternative is to make sure cdspell is not set.  The second 
alternative is to set the value of bin through

cd "$bin" && bin=${PWD}

This allows bin to take on the correct value no matter whether cdspell 
is set or not.
