在Ubuntu下安装海思sdk时，直接运行安装脚本，会有如下提示：

./sdk.unpack: 4: ./sdk.unpack: ECHO: not found

./sdk.unpack: 6: ./sdk.unpack: WARN: not found

./sdk.unpack: 7: ./sdk.unpack: WARN: not found

./sdk.unpack: 8: ./sdk.unpack: ECHO: not found

./sdk.unpack: 20: ./sdk.unpack: ECHO: not found

./sdk.unpack: 22: ./sdk.unpack: run_command_progress_float: not found

./sdk.unpack: 24: ./sdk.unpack: ECHO: not found

./sdk.unpack: 26: ./sdk.unpack: run_command_progress_float: not found

./sdk.unpack: 37: ./sdk.unpack: ECHO: not found

mkdir: 已创建目录 'mpp'

./sdk.unpack: 39: ./sdk.unpack: run_command_progress_float: not found

./sdk.unpack: 42: ./sdk.unpack: ECHO: not found

mkdir: 已创建目录 'drv'

./sdk.unpack: 44: ./sdk.unpack: run_command_progress_float: not found
