.SH SYNOPSIS

\fBunset \fIname \fR?\fIname name ...\fR?

.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.
