File::CheckTree(3Perl Programmers Reference GuiFile::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 sup
ply 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.
