Recursive directory listing - Enhanced RDIR

Files and directories listing, including recursive and other special features

Description

Enhanced version of RDIR function, fixing some bugs and adding some features.

- Basic use is similar to Matlab "dir" function, which allow you to list files and directories in a given path :

  rdir([matlabroot, '\*.txt'])

When asked, rdir output structure is the same as dir output structure :

  d = rdir([matlabroot, '\*.txt'])

- As initial RDIR function, you can use a double wildcard (**) to list files in all subdirectories from a given path :

  rdir([matlabroot, '\**\*tmpl*.m'])

And also use a filter entered as 2nd argument to refine your search :

  rdir([matlabroot, '\**\*tmpl*.m'], 'bytes>0')

This enhanced version of RDIR allow you to define filter on all fields of returned structure and also to use functions like "regexp" or "strfind" on "name" field.

- You can then add as 3rd argument a path to remove from beginning of "name" field of each listed item :

  rdir([matlabroot, '\*.txt'], '', 'C:\Program Files\')
All in : C:\Program Files\

- ".svn" directories created by SubVersion (SVN) are excluded from the recursive listing.

See published example for more details on how to use all RDIR capabilities.

Works great and saved me a lot of time.
A suggested improvement, instead of looking at the file size to identify directories, use the isdir flag.
Line 286: if D(ii).isdir %sz<0,
Change display to allow for 0b files
Line 291-293:
ss = max(0,min(4,floor(log2(sz)/10)));
disp(sprintf('%4.0f %1sb %20s %-64s ',...
sz/1024^(ss+eps),pp{ss+1}, datestr(D(ii).datenum, 0), D(ii).name));

Very useful indeed!
I am not sure if I am missing something, but unfortunately I am not able to make it finding multiple files with same name (even if in different folders). This would be a great improvement!

[Andrea]

Sorry... manage to have it working!

[Thomas Vanaret]

Thank you Alan for your suggestion.
Problem has been fixed in new version available (2.2).

Thanks, that was really useful in a selective by-size backup
