Re: unlink fails to delete files with perculiar names

in reply to unlink fails to delete files with perculiar names

If you had warnings enabled, you'd see that part of your filename is being taken as a perl variable for interpolation:

$targ = "D:/Users/Dave/Documents/Personal/CV/~$rriculum Vitae - 09 Jun
+e 2007.doc";;
Use of uninitialized value $rriculum in concatenation (.) or string at
+ (eval 17) line 1, <STDIN> line 10.
[download]

Just escape the $ with \:

$targ = "D:/Users/Dave/Documents/Personal/CV/~\$rriculum Vitae - 09 Ju
+ne 2007.doc";;
[download]

And the subsequent unlink will likely work.

The OP doesn't say how `$targ` was set. It's merely speculation that he assigned it using a double-quoted literal. It might just as well have come from a readdir or whatever. Also, why would unlink have returned 1, as the OP states? That should only have happened in the (unlikely) case there also was a file `'D:/Users/Dave/Documents/Personal/CV/~ Vitae - 09 June 2007.doc'` around at the time of the unlink call.

It's merely speculation that he assigned it using a double-quoted literal Agreed. That's why likely work. It might just as well have come from a readdir But don't you have to combine the values from readdir with the path in order to get a fully qualified path? Could he be doing something like `$targ = "$path/$fname";`? why would unlink have returned 1, as the OP states? Not sure, but that construct looks suspect to me: `my($no) = unlink $targ \|\| carp "Unable to delete file $targ\n";`. What ends up in `$no` if unlink returns 0; the return value from `carp()`?

Yup `$ perl -MCarp -e " my $f = unlink (666) \|\| carp 1; die $f " 1 at -e line 1 1 at -e line 1.` [download]	[reply] [d/l]

in my full code I get the file name using File::Find. From a windows directory listing from the command line the file is invisible, also from an explorer window...and from the application (MS word in this case) that presumeably created this as a temporary file it is also invisible.	[reply]

I tried escaping the $ with a \ that did not work ....	[reply]

Then I suggest you try `del "D:\Users\Dave\Documents\Personal\CV\~$rriculum Vitae - 09 June 2007.doc"` on a command line and see what error message is produced by the shell. Update: Having seen one of your other replies, try doing: `attrib -h -s -r "D:\Users\Dave\Documents\Personal\CV\~$rriculum Vitae +- 09 June 2007.doc"` [download] And then the unlink or `del`.
