xp_cmdshell is a system extended procedure that allows a database server to execute external shell commands. This functionality was available in Sybase IQ 12.7 and prior versions.
For details, see Adaptive Server Anywhere SQL Reference Manual on the Sybase Infocenter.
In Chapter 7 of Adaptive Server Anywhere SQL
Reference, the section “System extended stored
procedures” states that users must be granted EXECUTE permission
or have DBA authority. Several of the subsequent procedures, however,
show permissions listed as none, including xp_cmdshell.
xp_cmdshell requires DBA authority.
