File::CheckTree(3) File::CheckTree(3)
NAME
validate - run many filetest checks on a tree
SYNOPSIS
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"
});
DESCRIPTION
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.
