    #### Ways recommended: find "-$(RM) $(ULT_BIN)" by awk command.
    #awk '/\$\(CURDIR\)\/\%\.o\: \%\.cpp/{printf( "[%s:%d]: %s\n", FILENAME, NR, $0) }' ${FILE}
    #awk '/-lprint$/{printf( "[%s:%d]: %s\n", FILENAME, NR, $0) }' ${FILE}

    #### replace "-$(RM) $(ULT_BIN)" with "-$(RM) $(ULT_BIN) $(ULT_LIBS)" using awk command.
    # awk '{sub(/-\$\(RM\) \$\(ULT_BIN\)/,"-\$\(RM\) \$\(ULT_BIN\) \$\(ULT_LIBS\)"); print $0}' ${FILE} > ${FILE}.tmp; cp ${FILE}.tmp ${FILE}; rm -rf ${FILE}.tmp


    #### find "-$(RM) $(ULT_BIN)" by sed command.
    #sed -n "/\$(CURDIR)\/\%.o: \%.c$/p" ${FILE}

    #### Ways recommended: Step1. replace "-$(RM) $(ULT_BIN)" with "-$(RM) $(ULT_BIN) $(ULT_LIBS)" using sed command.

    ## 替换
    sed -i 's#\$(CURDIR)\/\%.o: \%.cpp$#\$(CURDIR)\/\%.o: \$(CURDIR)\/\%.cpp#g' ${FILE}

    ## 替换
    sed -i 's#\$(CURDIR)\/\%.o: \%.c$#\$(CURDIR)\/\%.o: \$(CURDIR)\/\%.c#g' ${FILE}

    ## 替换
    sed -i 's#$(bin).o#\$(CURDIR)\/$(bin).o#g' ${FILE}

    ## 追加（以  $$@  结尾）
    sed -i '/ -o \$\$\@$/ a\
    @echo \"========================Success========================\"' ${FILE}

    ## 追加（以  $$@ $$^)  结尾）
    sed -i '/\$\$\@ \$\$\^)$/ a\
    @echo \"========================Success========================\"' ${FILE}
done
