Should I choose ActivePerl or Strawberry Perl for Windows? [duplicate]

...reated for Windows and so some CPAN modules will not work (because they do Unix-specific things). I have used both before and it seemed to work for most cases.

Solaris has its own sh which for a long time was not POSIX-compliant; a free implementation is available from the Heirloom project. How can you find out what /bin/sh points to on your system?

Linux: copy and create destination dir if it does not exist

...ctory. Note that $_ is not part of the POSIX standard, so theoretically a Unix variant might have a shell that doesn't support this construct. However, I don't know of any modern shells that don't support $_; certainly Bash, Dash, and zsh all do. A final note: the command I've given at the start...

What's the difference between UTF-8 and UTF-8 without BOM?

...TF-8 files with BOM, so it's clearly possible. I think maybe you meant the Unix-land cat won't give you a clean result, a result that has BOM only at the start. If you meant that, then that's because cat works at the byte level, not at the interpreted contents level, and in similar fashion cat can't...

Why does Unicorn need to be deployed together with Nginx?
