+The <code>fg</code> command allows us to continue a stopped operation by running it in foreground.
+<br>
+
+<br>
+The command name stands for <i>foreground</i>.<br><br>
+
+<h3>Usage</h3>
+
+The default fg command syntax is:
+
+<pre>
+fg [%job_number]
+</pre>
+
+The parameter [%job_id] contains the job number you wish to run in foreground. If this is not indicated,
+the command will run the last stopped operation.
