NAME

     validate - 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 con-
     sisting 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 option-
     ally have a "!' prepended to test for the opposite condi-
     tion.  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 mes-
     sage).  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.
