unlink - remove one link to a file
unlink
LIST
unlink
Deletes a list of files. Returns the number of files successfully deleted.
$cnt = unlink 'a', 'b', 'c';
unlink @goners;
unlink <*.bak>;
Note: unlink() will not delete directories unless you are superuser and the -U flag is supplied to Perl. Even if these conditions are met, be warned that
unlinking a directory can inflict damage on your filesystem. Use rmdir() instead.
If
LIST is omitted, uses $_.
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.
