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.


DISCLAIMER

We are painfully aware that these documents may contain incorrect links and misformatted HTML. Such bugs lie in the automatic translation process that automatically created the hundreds and hundreds of separate documents that you find here. Please do not report link or formatting bugs, because we cannot fix per-document problems. The only bug reports that will help us are those that supply working patches to the installhtml or pod2html programs, or to the Pod::HTML module itself, for which I and the entire Perl community will shower you with thanks and praises.

If rather than formatting bugs, you encounter substantive content errors in these documents, such as mistakes in the explanations or code, please use the perlbug utility included with the Perl distribution.
