File::CheckTree(3)	       User Contributed Perl Documentation	       File::CheckTree(3)

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.
