As for the sprintf line, this session under the debugger shows you how the $mode value (coming from stat($file)[2]) might be converted:

  DB<1>  @c = stat "data.txt";

  DB<2> x @c
0  1946693715
1  6473924464489865
2  33261
3  1
4  1001
5  513
6  0
7  64
8  1375303088
9  1375303088
10  1375303088
11  65536
12  1
  DB<3>  $mode = $c[2];

  DB<4>  printf "%04o", $mode ;
100755
  DB<5>  printf "%04o", $mode & 07777;
0755

BTW, my "data.txt" does indeed have the 0755 permissions:

$ ls -l data.txt
-rwxr-xr-x 1 Laurent None    64 31 juil. 22:38 data.txt

In the Unix file permission system, "rwxr-xr-x" is the same as the 0755 octal value.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
