Exiv2

This is an artefact of cmd.exe's command to argv/argc parsing and has nothing to do with Exiv2(.exe).

I have a very useful little program "args.cpp" for debugging shell arguments. (args is a command on the Apollo Domain OS).

#include <stdio.h>
int main(int argc, char* argv[])
{
    int i = 1 ;
    while ( i < argc ) {
        printf("%-2d: %s\n",i,argv[i]) ;
        i++;
    }
    return 0 ;
}

args.exe enumerates and echoes arguments passed to it. Using this on your command line reveals:

C:\>args exiv2 -et DS C00498.JPG -l "C:\Documents and Settings\jeff.WOEHLER\Local Settings\Temp\" 
1: exiv2
2: -et
3: DS
4: C00498.JPG
5: -l
6: C:\Documents and Settings\jeff.WOEHLER\Local Settings\Temp" 

C:\>

You can see that argument 6 has the " appended. cmd.exe has passed the token \" as literal ". The correct syntax is to double the \ (i.e. escape the escape. The token \\ is passed as \ and the " closes the quoted string.

C:\>args exiv2 -et DS C00498.JPG -l "C:\Documents and Settings\jeff.WOEHLER\Local Settings\Temp\\" another-arg
1: exiv2
2: -et
3: DS
4: C00498.JPG
5: -l
6: C:\Documents and Settings\jeff.WOEHLER\Local Settings\Temp\
7: another-arg

Horrible? You betcha.
