in thread Automatically Rewrite Shebang Line on Multiple Files

Your solution with a for loop has the word perl within it. Is this a script in a language other than perl, or is there some significance to the use of "perl -pi.bak"? I'm not familiar with cygwin - the last time I tried to install it something didn't work right.

Regards,
Scott

    It's a Windows shell (cmd) command. If you need it in a batch file, you need to escape the %. Change %q to %%q.

    I'm not familiar with cygwin

    Cygwin is a OS emulator, not a shell or a scripting language. When people say Cygwin, they usually refer to bash and/or GNU tools. samtregar showed that a solution can be obtained using bash and GNU tools. I showed that such tools weren't required.

    is there some significance to the use of "perl -pi.bak"

    It invokes perl. -p and -i are documented in perlrun.
