I just installed Cygwin, which I've used off and on since it was created.
I've been using MinGw for several months and have a .bashrc file that sets
up some environment variables for me to reduce the typing in some routine
tasks. The file has the following form, after modifying the first line from
MinGw's format to Cygwin's:
The intent is to make $LL refer to /cygdrive/D/Common/labs. If I execute
those commands at the bash prompt, I get the desired effect:
"echo $LL" produces "/cygdrive/D/Common/labs"
But when I do
$ . .bashrc (or ./.bashrc, either one)
$ echo $LL
When I experiment with various paths for DD and LL, I see the following
pattern. The beginning of the DD string is overwritten with the LL string.
For instance, DD=/abcdef/ghi/jklmn; LL=/opqr yields $LL=/opqref/ghi/jklmn.
I don't get this behavior in any other Linux-ish installation I have: either
MinGw, OS X, or any of my Linuces.
Since bash is a GNU product, I'm sure this is a "feature". So I only need
to know how to get what I want.
And I'm sure you'll ask: the output of "sh --version" includes "GNU bash,
version 4.1.10(4)-release (i686-pc-cygwin).
