pathname

I use Perl on windows(Active Perl). I have a perl program to glob the files in current folder, and concatenate them all using dos copy command called from within using system()... When i execute, this gives a dos error saying "The system cannot find the file specified." It's related to the spaces in the filenames I have. This is the perl code :- @files = glob "*.mp3"; $outfile = 'final.mp3'; $firsttime = 1; foreach (@files) { if($firsttime == 1) { @args = ('copy' ,"/b ","$_","+","$outfile", "$outfile"); system (@args); #system("copy /b '$_'+$outfile $outfile"); $firsttime = 0; } else { @args =

We know root directory is /, and according to posix, there is another directory // which differs from /. When you ls / and ls //, the output is the same, so as stat, however if you cd / and cd //, they are different, though the directory content are the same. That really confused me.

This is, I presume, for historical compatibility. Certain versions of

This question already has an answer here: Difference between forward slash (/) and backslash (\) in file path 7 answers What is the difference in using a forward slash and backslash in navigating file systems. Also what is the difference between ./ and ../ ? sepp2k Well, in most languages backslashes need to be escaped in string literals, slashes do not. Further backslashes only work on Windows, while slashes work pretty much everywhere. On the other hand, when passing path names as arguments to Windows programs, using slashes might not work because many Windows programs use slashes to signify

I am making a software in C# and MATLAB that calls another software (CMG) to do some processing. My problem is that the address of the software I have put in my program is only correct on my personal computer and not on the customers' computers (I don't know what would be the path to CMG software on their computer). How can I provide a general form of the address in order to make it work on every computer? The following is the path I call from my MATLAB software: C:\Program Files (x86)\CMG\STARS\2011.10\Win_x64\EXE\st201110.exe As you see it is in drive C and the version is 2011.10. So if
