Re: Strange cygpath/Perl 5.8 interaction?

It is not perl adding and extra line feed.  It is bash automatically
removing a line feed...

    $ echo "|"`pwd`"|"
    $ pwd |od -t x1
    0000000 2f 74 6d 70 0a

Bash will remove the \n for you automatically when using `pwd`, perl won't.
To tell perl to remove the trailing "\n" use the chomp function.

    $ perl -e 'chomp($a=`pwd`);print "|".$a."|\n";'
