    <p>Exclude directories with <code>-prune</code> option:</p> <pre><code>find . -type d -name ProductA -prune -o -type d -exec chmod 755 {} \; </code></pre> <p>It tells: if file is a directory and has name <code>ProductA</code>, then do not descend into it (<code>-prune</code>), else (<code>-o</code> means or) if file is a directory, then execute the <code>chmod 755</code> on it.</p> <p><code>find</code> expressions are made of options, tests (can be false or true) and actions, separated by operators. When no action is given, then <code>-print</code> action is performed on all files for which the expression is true. <code>-exec</code> is an action, <code>-prune</code> is another. You can chain multiple actions with <code>-a</code> and <code>-o</code>. <code>expr1 -a expr2</code> will execute both actions, whereas <code>expr1 -o expr2</code> will execute <code>expr2</code> only if <code>expr1</code> evaluates to false.</p> <p>So if you want to exclude multiple directories, you can write</p> <pre><code>find . -type d -name ProductA -prune -o -type d -name ProductC -prune -o -type d -exec chmod 755 {} \; find . -type d -name ProductA -prune -o -type d -name ProductC -prune -o -type f -exec chmod 644 {} \; </code></pre> <p>or just:</p> <pre><code>find . -type d -name "Product[AC]" -prune -o -type d -exec chmod 755 {} \; find . -type d -name "Product[AC]" -prune -o -type f -exec chmod 644 {} \; </code></pre> <p>and you can combine them too:</p> <pre><code>find . -type d -name "Product[AC]" -prune -o -type d -exec chmod 755 {} \; -o -type f -exec chmod 644 {} \; </code></pre> <p>If you have a more complex directory structure, say you want to exclude <code>ProductA/data</code> but not <code>ProductB/data</code> nor <code>ProductA/images</code>, then you can use the <code>-path</code> test:</p> <pre><code>find . -path ./ProductA/src -prune -o -print </code></pre>

    1. COvery good, thanks, but what should i do if i want to ignore all files inside the excluded folders. For example, lets say i want to exclude "ProductA" and "ProductC" folders, but also ignore all their files.

    3. COUse this command: `find . -type d -name ProductA -prune -o -type f -exec chmod 644 {} \;`. It will go through files and directories recursively. If the directory named `ProductA` is found, then it will be _pruned_ from the search, meaning that all files that belong to ProductA directory will be excluded. So you will change permissions only to the other files. You can check found files by asking `find` to print them with `find . -type d -name ProductA -prune -o -type f -print`

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
