Top Forums Shell Programming and Scripting Conditional output redirection Post 302972961 by chebarbudo on Thursday 12th of May 2016 07:15:24 AM

mycommand outputs a list of files in a human readable form (newline separated). But I might run into weird filenames so I added the option --null to mycommand so it prints files separated by the NUL character. What I do with the data is:
Code:
mycommand --null | xargs --null cp --target-directory="$mydir"

mycommand fails in specific situations and I don't want any output to be piped to cp in such a case.

I could for sure use a temporary file but I like (as a personal fanciness) to avoid that.

Does it make any sense in your opinion?

http_redirect - Issue HTTP redirect

SYNOPSIS
bool http_redirect ([string $url], [array $params], [bool $session = false], [int $status]) DESCRIPTION
Redirect to the given url. The supplied $url will be expanded with http_build_url(3), the $params array will be treated with http_build_str(3) and the session iden- tification will be appended if $session is true. The HTTP response code will be set according to $status. You can use one of the redirect constants for convenience. Please see RFC 2616 for which redirect response code to use in which situation. By default PHP will decide which response status fits best. To be RFC compliant, "Redirecting to <a>URL</a>." will be displayed, if the client doesn't redirect immediately, and the request method was another one than HEAD. A log entry will be written to the redirect log, if the INI settinghttp.log.redirect is set and the redirect attempt was successful. PARAMETERS
o $url - the URL to redirect to o $params - associative array of query parameters o $session - whether to append session information o $status - custom response status code RETURN VALUES
Returns FALSE or exits on success with the specified redirection status code. See the INI settinghttp.force_exit for what "exits" means. EXAMPLES
Example #1 A http_redirect(3) example <?php http_redirect("relpath", array("name" => "value"), true, HTTP_REDIRECT_PERM); ?> The above example will output: HTTP/1.1 301 Moved Permanently X-Powered-By: PHP/5.2.2 Content-Type: text/html Location: http://www.example.com/curdir/relpath?name=value&PHPSESSID=abc Redirecting to <a href="http://www.example.com/curdir/relpath?name=value&PHPSESSID=abc">http://www.example.com/curdir/relpath?name=value&PHPSESSID=abc</a>.
