In command-line paser we can identify a command output may input to another command . So implement own piping machanisum for combaine commands (search, replace, merge) make help to minimue uncompress/compress attempts.

> GNU/Linux, and UNIX before then has shown the great power of a text processing via simple command line tools, combined with operating facilities for piping and redirection. This filter-baed text processing is what makes shell programming so powerful.  But it only works well for text documents.  But what about more complex, WYSIWYG documents, spreadsheets, word processors, with more complex formats, often not text based at all?  The tool set becomes far weaker.
> The Apache ODF Toolkit is a Java API that gives a high level view of a document, and enables programmatic manipulation of a document.  We have functions for doing things like search & replace.  There is a lot you can do using the ODF Toolkit.  But it still requires Java programming, and that limits its reach to professional programmers.
> What if we could write, using the ODF Toolkit, a set of command line utilities that made it easy to do both simple and complex text manipulation tasks form a command line, things like:
> 1) Concatenate documents
> 2) Replace slide 3 in presentation A with slide 3 from presentation B
> 3) Apply the styles of document A to all documents in the current directory
> 4) Find all occurances of "sausages" in the given document and add a hyperlink to sausages.com
> and so on.
> Clearly analogs of cat, grep, diff and sed are obvious ones. Maybe something awk-like that works with spreadsheets?  No need to be slavish to the original tools, but create something of similar power, but which operate on ODF documents.  For example, an alternative solution might be to write a new shell processor that has native commands for ODF document manipulation.
