Author FAQ 5.34 Why can't I use "C:\temp\foo" in DOS paths? Why doesn't `C:\temp\
PerlFAQ Server

This message is one of several periodic postings to comp.lang.perl.misc
intended to make it easier for perl programmers to find answers to
common questions. The core of this message represents an excerpt
from the documentation provided with Perl.

--------------------------------------------------------------------

5.34: Why can't I use "C:\temp\foo" in DOS paths? Why doesn't `C:\temp\foo.exe` work?


Whoops! You just put a tab and a formfeed into that filename! Remember
that within double quoted strings ("like\this"), the backslash is an
escape character. The full list of these is in "Quote and Quote-like
Operators" in perlop. Unsurprisingly, you don't have a file called
"c:(tab)emp(formfeed)oo" or "c:(tab)emp(formfeed)oo.exe" on your legacy
DOS filesystem.

Either single-quote your strings, or (preferably) use forward slashes.
Since all DOS and Windows versions since something like MS-DOS 2.0 or so
have treated "/" and "\" the same in a path, you might as well use the
one that doesn't clash with Perl--or the POSIX shell, ANSI C and C++,
awk, Tcl, Java, or Python, just to mention a few. POSIX paths are more
portable, too.

Absolutely false. This is another example of a Perl FAQ promulgating
totally bogus information.

This FAQ is mondo beyondo stupid.

It's been time for a while, but nobody has done it. Don't wait for me; I
don't use Windows. :)

All of the questions are on a single line. To wrap them we'd have to
rewrite a lot of the tools that deal with the perlfaq (probably
involving a much more complicated parser).

The trick is to come up with shorter questions.
