Hello PhillyR,

With the ls utility from GnuWin tools you can use ls -i to get the inode of the monitored directory. If the user subsequently renames the directory, its inode number remains unchanged, allowing you to identify the directory and retrieve its new name.1 Here is some proof-of-concept code (minus error checking!):

#! perl use strict; use warnings; my $dir = 'foo'; my $ls = (grep { /\s+$dir$/ } `ls -il`)[0]; $ls =~ /^\s*(\d+)/; my $inode = $1; print "$dir --> $inode "; rename $dir, 'bar'; $ls = (grep { /^\s*$inode\s+/ } `ls -il`)[0]; $ls =~ /:\d{2}\s+(.*)$/; print "--> $1\n";


13:09 >perl foo --> 7318349394599033 --> bar 13:09 >

(Tested on an NTFS file system under Windows 8.1, 64-bit.)

Hope that helps,

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • 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.
