File::CheckTree(3pm)                  Perl Programmers Reference Guide                  File::CheckTree(3pm)



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 <[email protected]> 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.
