Top Forums UNIX for Dummies Questions & Answers Help identifying empty directories Post 88875 by Perderabo on Wednesday 9th of November 2005 02:07:46 PM

Whoa! Here's some syntax that I've never seen before...

command1 > somefile | command2

What is that supposed to do? I tested it and I found that all of command1's output went to the file and nothing went to the pipe. But this means your while loop should run zero times. So I can't explain how you get anything. It looks to me like you should get nothing. And when I try your code, I do get nothing.

After I removed "> dir.txt", it seemed to work for me.

The -depth does no good so I would get rid of that. If a directory has subdirctories, it is not empty and does not need to be checked. You should check only "leaf directories". To do that add "-links 2" to your find statement (think about it). And you have a bug. A directory containing only ".secretfile" is not empty. Do a "ls -a" and check for 3 or more entries. ls sorts its output and a sort can take time. "ls -fa" will bypass the sort and possibly speed stuff up.

But I have no idea why you are getting everything. Smilie

WRAP-AND-SORT(1)					      General Commands Manual						  WRAP-AND-SORT(1)

NAME
wrap-and-sort - wrap long lines and sort items in Debian packaging files SYNOPSIS
wrap-and-sort [options] DESCRIPTION
wrap-and-sort wraps the package lists in Debian control files. By default the lists will only split into multiple lines if the entries are longer than 80 characters. wrap-and-sort sorts the package lists in Debian control files and all .install files. Beside that wrap-and-sort removes trailing spaces in these files. This script should be run in the root of a Debian package tree. It searches for control, control.in, copyright, copyright.in, install, and *.install in the debian directory. OPTIONS
-h, --help Show this help message and exit. -a, --wrap-always Wrap all package lists in the Debian control file even if the entries are shorter than 80 characters and could fit in one line line. -s, --short-indent Only indent wrapped lines by one space (default is in-line with the field name). -b, --sort-binary-packages Sort binary package paragraphs by name. -k, --keep-first When sorting binary package paragraphs, leave the first one at the top. Unqualified debhelper(7) configuration files are applied to the first package. -n, --no-cleanup Do not remove trailing whitespaces. -d path, --debian-directory=path Location of the debian directory (default: ./debian). -f file, --file=file Wrap and sort only the specified file. You can specify this parameter multiple times. All supported files will be processed if no files are specified. -v, --verbose Print all files that are touched. AUTHORS
wrap-and-sort and this manpage have been written by Benjamin Drung <bdrung@debian.org>. Both are released under the ISC license. DEBIAN
