"Failed to execute command" and subsequent 500 response

[GoogleCodeExporter]

I am giving a number of commands to be executed in a single SSH sampler.
e.g. 

rm -rf ${TEST_NAME};
mkdir ${TEST_NAME};
sleep 1;
chmod 777 ${TEST_NAME};
cd ${OUTPUT_DIR}/${TEST_NAME};
cp ${CONF_FILE_DIR}${CONF_FILE_NAME}.xml  . ;
cp ${CONF_FILE_DIR}${CONF_FILE_COPY_NAME}.xml . ;
diff ${CONF_FILE_DIR}${CONF_FILE_NAME}.xml 
${CONF_FILE_DIR}${CONF_FILE_COPY_NAME}.xml > ${TEST_NAME}.diff;

This steps fails with "Failed to execute command" response.

All the subsequent SSH samplers fail with 500 response.
