Bash Version: 4.1

Patch Level: 10

Release Status: release

 

Description:

       When I attempt to execute a bash script with DOS line endings, I
get

        numerous errors concerning the \r at the end of each line.

 

        This was not always true.  When I first started to regularly use

        cygwin in 2003 we had numerous bash scripts, with DOS line
endings,

        that we used to maintain our product.  When I returned to the
same 

        employer in 2009, having been laid off in 2007, and got the
latest

        distribution of cygwin, I was surprised that none of our old
scripts

        worked until I went through and converted to unix line endings.

 

        I thought this must surely be a simple goof that would be fixed
in the

        next release, but when I reloaded cygwin for my new PC late last
year

        the bug was still there.

 

Repeat-By:

       Take any working bash script file, pass through unixtodos (or
edit with

        vi/vim/gvim, set fileformat=dos, and write out), and attempt to
run.
