NAME

SYNOPSIS

9           use File::CheckTree;
10
11           $num_warnings = validate( q{
12               /vmunix                 -e || die
13               /boot                   -e || die
14               /bin                    cd
15                   csh                 -ex
16                   csh                 !-ug
17                   sh                  -ex
18                   sh                  !-ug
19               /usr                    -d || warn "What happened to $file?\n"
20           });

DESCRIPTION

23       The validate() routine takes a single multiline string consisting of
24       directives, each containing a filename plus a file test to try on it.
25       (The file test may also be a "cd", causing subsequent relative
26       filenames to be interpreted relative to that directory.)  After the
27       file test you may put "|| die" to make it a fatal error if the file
28       test fails.  The default is "|| warn".  The file test may optionally
29       have a "!' prepended to test for the opposite condition.  If you do a
30       cd and then list some relative filenames, you may want to indent them
31       slightly for readability.  If you supply your own die() or warn()
32       message, you can use $file to interpolate the filename.
33
34       Filetests may be bunched:  "-rwx" tests for all of "-r", "-w", and
35       "-x".  Only the first failed test of the bunch will produce a warning.
36
37       The routine returns the number of warnings issued.

AUTHOR

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

HISTORY

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