Re: Using File::DosGlob::glob in loop only works first time

Using glob in scalar context is a bad idea. Is there a reason you're doing this?

The quick fix is to do -f (File::DosGlob::glob qq{"$template_file"})[0] which puts the glob into list context.

No reason other than uninformed DWIMmery. :-) Thanks, your suggestion works perfectly in my real code. Changing the first line here (and leaving the second alone) to: `unless ( -f ( File::DosGlob::glob qq{"$template_file"} )[0] ) +{` [download] produces: `ftf2: 'file_a.txt' ftf2a: '"file_a.txt"' ftf2b: 'file_a.txt' is okay. ftf2: 'file_b.txt' ftf2a: '"file_b.txt"' ftf2b: 'file_b.txt' is okay. ftf3: 'file_b.txt' ftf3a: '"file_b.txt"' ftf2b: 'file_b.txt' is okay. ftf3: 'file_a.txt' ftf3a: '"file_a.txt"' 8251b: File check, cannot access 'file_a.txt', No such file or directo +ry` [download]	[reply] [d/l] [select]

I guess my more important question is: why are you using glob()? Are these fileglobs or filenames? Why are you using glob() on something that's not a glob? Is it for some evil windows reason?
