    <p>The canonical answer is to create scripts containing these commands.</p> <p><strong>Edit</strong> Supposing you have the following history entries;</p> <pre><code>find /var/www -name '*.html' -exec fgrep '&lt;title&gt;' {} /dev/null \; find ~/public_html -name '*.php' -exec fgrep include {} /dev/null \; </code></pre> <p>... you can try to isolate the parameters into a function something like this;</p> <pre><code>r () { find "$1" -name "*.$2" -exec fgrep "$3" {} /dev/null \; } </code></pre> <p>... which you could use like this, to repeat the history entries from above:</p> <pre><code>r /var/www html '&lt;title&gt;' r ~/public_html php include </code></pre> <p>Obviously, the step is then not very long to create a proper script with defaults, parameter validation, etc. (Hint: you could usefully default to the current directory for the path, and no extension for the file name, and add options like <code>--path</code> and <code>--ext</code> to override the defaults when you want to; then there will be only one mandatory argument to the script.)</p> <p>Typically, you would store the script in <code>$HOME/bin</code> and make sure this directory is added to your <code>PATH</code> from your <code>.profile</code> or similar. For functions, these are usually defined in <code>.profile</code>, or a separate file which is <code>source</code>d from this file.</p> <p>Having it in a central place also helps develop it further; for example, for precision and perhaps some minor added efficiency, you might want to add <code>-type f</code> to the <code>find</code> command; now there is only one place to remember to edit, and you will have it fixed for good.</p>

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.
