(DOS Batch) Split output of dir command into parts - bits

Thu, 10 Feb 2011 10:10:31 GMT

This example shows how you can split the output lines of e.g. a dir command. It also shows how to use a pipe to reduce the resulting lines by the findstr command. Explanation: This command calls "dir *.dll" and filters the results by findstr command through a pipe "|". The result of this is a list of all dll-files which contains the string "text" in it's name. Now the for-loop takes each of these lines and splits them by the signs given in the "delims=.: " part. The "tokens=1,2,3" will send the first three parts of the split string to the explicit defined variable %i and the implicit defined variables %j and %k. You can start counting your variables from every sign between a-z or A-Z. You will get more information about this on your command line with "for /?". If you want to use this in a batch file, replace all % with %%. This example will give you the date of alle found files in the format DD MM JJJJ (on a german windows box). If you use mor than three tokens or other characters as delims, you can get different results. Just play around.

(Bash) Howto run Tidy from the command line - noah

Fri, 05 Feb 2010 12:41:54 GMT

This shell command will retrieve a Web page and validate the HTML with [Tidy, the HTML linter from the W3](http://tidy.sourceforge.net/). You can get an **XHTML validation** report right in your shell prompt, just like you'd get from the [Firefox extension](https://addons.mozilla.org/en-US/firefox/addon/249) or the [Web service.](validator.w3.org/). It's especially helpful when you need to **validate HTML on your intranet, or behind a firewall.** ### **NOTE: Curl does not follow redirects by default!** By default, Curl retrieves *exactly* the URL you specify. The `-L` option causes Curl to follow redirects just like a Web browser would. ### **NOTE: Tidy produces a lot of output!** Windows users should make sure their [command prompt screen buffer height is set to 9999](http://www.codinghorror.com/blog/archives/000334.html 'command prompt tips from Coding Horror') so that you don't "lose" any output. ### **Explanation of the command line options** `curl -L` tells Curl to fo**LL**ow HTTP redirects `curl -s` **S**uppresses Curl's annoying progress bar `tidy -e` tells Tidy not to **E**mit the tidied HTML to the console `tidy -q` tells Tidy to be **Q**uiet, instead of printing extra crap at the bottom of the report ### **Dependencies** Curl and Tidy are installed via the [Cygwin setup.exe](http://cygwin.com/) Alternately, Perl hackers could use [lwp-request](http://search.cpan.org/~gaas/libwww-perl-5.808/bin/lwp-request). ### **Doing more** [Validate HTML with a stricter algorithm,](http://snipplr.com/view/4130/check-linked-pages-for-tidy-validation-errors-on-the-command-line/) using the OpenJade SGML parser. [Validate linked pages](http://snipplr.com/view/4130/check-linked-pages-for-tidy-validation-errors-on-the-command-line/) with Tidy and lwp-request.

(Java) Convert OutputSream into an InputStream - dvdsmnt

Sat, 14 Nov 2009 19:06:57 GMT

There are many ways to retrieve data written to an `OutputStream` in an `InputStream` class. An introduction can be found at [io-tools website](http://code.google.com/p/io-tools/wiki/ConvertOutputStreamInputStream) : # InputStreamFromOutputStream # This is the hardest way, but it offers some advantages: * This class internally use pipes, so it has a fixed memory fingerprint (doesn't fill up your memory with data). * Details of threads are hidden from the user. You don't have to deal with instantiation/start/synchronization/stop. * You can easily choose between many options for instantiating new Threads (thread pool, thread per instance ...) or just don't care and get the default. * Details of pipes are hidden. No PipeInputStream or PipeOutputStream in your code. * The internal pipe size can be adjusted to fit your needs.
