    <p>I need to insert datetime in every vmstat line that has value. </p> <p>I can create a function like this:</p> <pre><code>function insert_datetime { while read line do printf "$line" date '+ %m-%d-%Y %H:%M:%S' done } </code></pre> <p>then call vmstat as below:</p> <pre><code>'vmstat 3 5 | insert_datetime' </code></pre> <p>but this line puts date time to every line, including dashes (--) and any rows that has text. How can I exclude rows that has dahses and text?</p> <pre><code>kthr memory page faults cpu 04-23-2013 10:19:49 ----- ----------- ------------------------ ------------ ----------------------- 04-23-2013 10:19:49 r b avm fre re pi po fr sr cy in sy cs us sy id wa pc ec 04-23-2013 10:19:49 0 0 45688088 4094129 0 0 0 0 0 0 45 12172 2840 1 1 99 0 0.35 2.2 04-23-2013 10:19:49 2 0 45694135 4088082 0 0 0 0 0 0 451 56350 21818 3 1 97 0 0.73 4.5 04-23-2013 10:19:52 1 0 45694137 4088061 0 0 0 0 0 0 303 24568 951 3 1 96 0 0.82 5.1 04-23-2013 10:19:55 1 0 45694138 4087739 0 0 0 0 0 0 445 9170 1504 2 0 98 0 0.64 4.0 04-23-2013 10:19:58 4 0 45703145 4078732 0 0 0 0 0 0 335 47175 1306 4 1 95 0 1.01 6.3 04-23-2013 10:20:01 </code></pre> <p>I needed to look like this:</p> <pre><code>kthr memory page faults cpu ----- ----------- ------------------------ ------------ ----------------------- r b avm fre re pi po fr sr cy in sy cs us sy id wa pc ec 0 0 45688088 4094129 0 0 0 0 0 0 45 12172 2840 1 1 99 0 0.35 2.2 04-23-2013 10:19:49 2 0 45694135 4088082 0 0 0 0 0 0 451 56350 21818 3 1 97 0 0.73 4.5 04-23-2013 10:19:52 1 0 45694137 4088061 0 0 0 0 0 0 303 24568 951 3 1 96 0 0.82 5.1 04-23-2013 10:19:55 1 0 45694138 4087739 0 0 0 0 0 0 445 9170 1504 2 0 98 0 0.64 4.0 04-23-2013 10:19:58 4 0 45703145 4078732 0 0 0 0 0 0 335 47175 1306 4 1 95 0 1.01 6.3 04-23-2013 10:20:01 </code></pre>

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
