./dir/file
$ chmod ugo=x dir/
$ find; echo $?         # If the directory is not readable, find fails because it cannot explore it
.
./dir
find: `./dir': Permission denied
1
$ chmod ugo=r dir/      # If the directory is not cd-able, find does NOT fails although it cannot explore it
$ find; echo $?
.
./dir
0

How can I make sure find fails if it cannot list all files and folders?

Thanks in advance

Those are strange results. What operating system are you using?

Note that the results I would expect from a readable, unsearchable directory vary depending on whether or not there are any files (other than . and ..) in that directory. The find utility can find all of the files in a directory even if it is unsearchable, so if there aren't any files in that unsearchable directory, there is no reason for find to fail. But, if files are present in an unsearchable directory, find won't be able to stat() those files to determine if they are directories that also need to be searched (so it should fail).

But, if a directory is unreadable, the find utility can't determine whether or not there are any files in that directory (so it should fail).

The BSD-based find utility on OS X behaves as I expect. I don't have other versions of find readily available to test against my expectations.

Apache2::Build(3)					User Contributed Perl Documentation					 Apache2::Build(3)

NAME
Apache2::Build - Methods for locating and parsing bits of Apache source code SYNOPSIS
use Apache2::Build (); my $build = Apache2::Build->new; # rebuild mod_perl with build opts from the previous build % cd modperl-2.0 % perl -MApache2::Build -e rebuild DESCRIPTION
This module provides methods for locating and parsing bits of Apache source code. Since mod_perl remembers what build options were used to build it, you can use this knowledge to rebuild it using the same options. Simply chdir to the mod_perl source directory and run: % cd modperl-2.0 % perl -MApache2::Build -e rebuild If you want to rebuild not yet installed, but already built mod_perl, run from its root directory: % perl -Ilib -MApache2::Build -e rebuild METHODS
new Create an object blessed into the Apache2::Build class. my $build = Apache2::Build->new; dir Top level directory where source files are located. my $dir = $build->dir; -d $dir or die "can't stat $dir $! "; find Searches for apache source directories, return a list of those found. Example: for my $dir ($build->find) { my $yn = prompt "Configure with $dir ?", "y"; ... } inc Print include paths for MakeMaker's INC argument to "WriteMakefile". Example: use ExtUtils::MakeMaker; use Apache2::Build (); WriteMakefile( 'NAME' => 'Apache2::Module', 'VERSION' => '0.01', 'INC' => Apache2::Build->new->inc, ); module_magic_number Return the MODULE_MAGIC_NUMBER defined in the apache source. Example: my $mmn = $build->module_magic_number; httpd_version Return the server version. Example: my $v = $build->httpd_version; otherldflags Return other ld flags for MakeMaker's dynamic_lib argument to "WriteMakefile". This might be needed on systems like AIX that need special flags to the linker to be able to reference mod_perl or httpd symbols. Example: use ExtUtils::MakeMaker; use Apache2::Build (); WriteMakefile( 'NAME' => 'Apache2::Module', 'VERSION' => '0.01', 'INC' => Apache2::Build->new->inc, 'dynamic_lib' => { 'OTHERLDFLAGS' => Apache2::Build->new->otherldflags, }, ); AUTHOR
