Hmm, I believe the OP didn't want "/home/blah", he wanted
"C:/cygwin/home/blah". And for the /cygdrive/* cases, that's what cygpath
does. Also, cygpath comes with the cygwin package, and sed requires
installing a separate one.
Besides, you can do it much simpler in sed, something like
alias pwd='pwd | sed -e"s,^/cygdrive/\(.\),\1:," -eTz -e"s,/,\\\,g" -e:z'
Or, since the OP wanted the mixed style ('/' instead of '\') even this
alias pwd='pwd | sed -e"s,^/cygdrive/\(.\),\1:,"'
:-)
