Scratch my above example; cd is a shell builtin, so it won't work from xargs. I did $ mkdir "a'b \$c" for my experiments (make sure ', $, and multiple spaces make it through okay). In bash and zsh, the following works on the command line: cd "`cat<<\eof a'b $c eof `" (and you could use $() instead of ``). But ` and ) are also valid characters in Windows filenames, and bash, zsh, and pdksh all have bugs in parsing here-docs inside command substitutions. For example, bash fails on: cd "$(cat<<\eof ` eof )" Somehow, it thinks that ` starts a nested command substitution, even though it appears inside of a quoted here-doc. (And in the case of `, you must use $() instead of ``, since POSIX states that `` doesn't nest without proper quoting). Also, bash has a bug when the command-substitution is not also quoted: $ echo $(cat<<\eof > ` > eof > ) Again, bash (both 3.0 and 3.1) thinks the ` starts a nested command substitution, and is waiting for a matching ` before executing anything. Believe it or not, the ONLY shell which I found which correctly parses all the troublesome characters, as required by POSIX, is ash, which is the least POSIX-compliant of them all! Sorry, but I don't know ANY portable construct that works in all 4 cygwin shells (ash, bash, zsh, and pdksh). Plus there is still the matter of translating a valid command line into a registry entry that Windows can parse; I don't know if you can embed newlines, and without embedded newlines, a here-doc will not work. All I can do is wish you good luck. - -- Life is short - so eat dessert first!
