+.SH NAME
+unset \- Delete variables
+.SH SYNOPSIS
+\fBunset \fIname \fR?\fIname name ...\fR?
+.BE
+
+.SH DESCRIPTION
+.PP
+This command removes one or more variables.
+Each \fIname\fR is a variable name, specified in any of the
+ways acceptable to the \fBset\fR command.
+If a \fIname\fR refers to an element of an array then that
+element is removed without affecting the rest of the array.
+If a \fIname\fR consists of an array name with no parenthesized
+index, then the entire array is deleted.
+The \fBunset\fR command returns an empty string as result.
+An error occurs if any of the variables doesn't exist, and any variables
+after the non-existent one are not deleted.
+
+.SH KEYWORDS
+remove, variable
