NAME

       File::CheckTree - run many filetest checks on a tree

SYNOPSIS

           use File::CheckTree;

           $num_warnings = validate( q{
               /vmunix                 -e || die
               /boot                   -e || die
               /bin                    cd
                   csh                 -ex
                   csh                 !-ug
                   sh                  -ex
                   sh                  !-ug
               /usr                    -d || warn "What happened to $file?\n"
           });

DESCRIPTION

       The validate() routine takes a single multiline string consisting of directives, each containing a
       filename plus a file test to try on it.  (The file test may also be a "cd", causing subsequent relative
       filenames to be interpreted relative to that directory.)  After the file test you may put "|| die" to
       make it a fatal error if the file test fails.  The default is "|| warn".  The file test may optionally
       have a "!' prepended to test for the opposite condition.  If you do a cd and then list some relative
       filenames, you may want to indent them slightly for readability.  If you supply your own die() or warn()
       message, you can use $file to interpolate the filename.

       Filetests may be bunched:  "-rwx" tests for all of "-r", "-w", and "-x".  Only the first failed test of
       the bunch will produce a warning.

       The routine returns the number of warnings issued.

AUTHOR

       File::CheckTree was derived from lib/validate.pl which was written by Larry Wall.  Revised by Paul
       Grassie <grassie@perl.com> in 2002.

HISTORY

       File::CheckTree used to not display fatal error messages.  It used to count only those warnings produced
       by a generic "|| warn" (and not those in which the user supplied the message).  In addition, the
       validate() routine would leave the user program in whatever directory was last entered through the use of
       "cd" directives.  These bugs were fixed during the development of perl 5.8.  The first fixed version of
       File::CheckTree was 4.2.
