On HP Tru64 UNIX you need to set the BIN_SH environment variable to xpg4 before running the uninstall or it will fail. To set the BIN_SH environment variable:
For csh:
setenv BIN_SH xpg4
For sh:
BIN_SH=xpg4; export BIN_SH
Following the setting of the environment variable, call:
$SYBASE/uninstall/SDK/uninstall
If you do not set the environment variable the command fails with the following error:
$SYBASE/uninstall/SDK/uninstall: O^D@^A: is not an identifier
