*Change Request ID*: 6791838
*Synopsis*: *ksh93* unset of a variable which is not set should return 0
Product: solaris
Category: shell
Subcategory: korn93
Type: Defect
Subtype: Functionality
Status: 7-Fix in Progress
Substatus:
Priority: 3-Medium
Introduced In Release: solaris_nevada
Introduced In Build: snv_72
Responsible Engineer: <User 1-7MTUEB>
Keywords: ONPIT_OSOL_TRANSITION, oss-request, oss-sponsor
=== *Description* ============================================================
In ksh93, the special builtin "unset" will exit 1 when its argument is a
variable which is not set, but it should exit 0, according to the POSIX
standards.
The problem occurs with the ksh93 integrated into snv_72, as well as the
latest ksh93 (based on AT&T's ast-ksh 2008-11-04) integrated into snv_106.
In ksh93:
% unset foo
% echo $?
1
This behavior caused problems in Makefile scripts when ksh93 is used.
