Extracting particular files from a zoo archive file

Consider now that we do not want to extract all the files stored in EX1.ZOO but only those with a particular name or name component, say with the extension .C.

Recall the zoo dialog box by selection of the ``Zoo ...'' menu item. From the previous call the zoo archive file is still selected so the GEM file selector will not appear this time. Now we have to specify the files we want to extract: Move the text cursor to the ``Filename'' field, type *.C into it, then click at .

In many cases the ``Filename'' field is sufficient to specify the files you want to extract from an archive file. However, if you want to specify more files or selection patterns you can click at This will make another dialog box — the file selection handler — to appear. Here you have more fields to select filenames. You can even redirect standard input, standard output and select a working directory for the zoo program. A detailed description of the file selection handler you will find in section (page ).
