validate - run many filetest checks on a tree
use File::CheckTree;
$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"
});The validate() routine takes a single multiline string consisting of lines 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.
