Description: ------------ The tmpDir property is never correctly set. This is because the property name is tmpDir with an uppercase D but in the constructor the variable tmpdir is set instead. // Caputre a temporary directory for capturing stderr from commands $this->tmpdir = System::tmpdir(); if (!System::mkDir("-p {$this->tmpdir}")) { $this->_initError =& PEAR::raiseError(null, SYSTEM_COMMAND_TMPDIR_ERROR, null, E_USER_WARNING, null, 'System_Command_Error', return; } The fix is change all references to tmpdir to be tmpDir. Test script: --------------- $cmd = new System_Command() if (!empty($cmd->tmpDir)) { echo "tmpDir set to {$cmd->tmpDir}"; } else { echo "tmpDir is empty"; } Expected result: ---------------- tmpDir set to /tmp Actual result: -------------- tmpDir is empty

confirmed. roadmap for v1.0.6
