Re: Function "replace" for strings?

[LukasP <LP...@po...>]

... There's no doubt there are possibilities how to convert \ to /. The
solution suggested bellow is usable on Linux, but not in Windows - when I
need to convert hundreds of datafiles under Windows to png and when I use
command "dir /s /b *.dat", I get a list where "\" is used as directory
separator in file path.

Personally - on Windows - I use an ("ultra-easy") bksl2sl.exe utility, which
reads stdin, each occurance of "\" replaces by "/" and writes bytes to
stdout. It works, although its "non-standard".

... OK, I treat it as a possibility which works on Linux; it doesn't work on
Windows.

IMHO, I don't think it's the way of best performance - to create new
process, wait for the pipe until it is broken and the take the result. When
converting a large number of files, a built-in replacing function should be
much quicker, don't you think?

... Personally, no problem with using "/" for directory separator (and "-"
for command option). But it's otherwise on Windows - its commands use "\"
for path description and "/" as command separator; I cann't do nothing with
that.
