Body
Let's say I have some comma separated list of IP address: <pre><code>line = "10.5.23.21,12.23.123.4,5.23.4.234" </code></pre> I'd like to do hostname lookups on these IPs using a RegEx and a loop that passes the matches to the command line and runs dig: <pre><code>line.scan(/(\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3})/) do |ip| hostNamesHash[ip] = `dig -x #{ip} +short` end </code></pre> The problem is that this is actual command that gets run: <pre><code>`dig -x ["10.5.23.21"] +short` </code></pre> How can I change my code to make sure that #{ip} just passes in the literal value of ip, not the extra [""] along with it?

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.
