数据文件夹概览工具
IoTDB数据文件夹概览工具用于打印出数据文件夹的结构概览信息，工具位置为 tools/tsfile/print-iotdb-data-dir。
用法
- Windows:
1. .\print-iotdb-data-dir.bat <IoTDB数据文件夹路径，如果是多个文件夹用逗号分隔> (<输出结果的存储路径>)
- Linux or MacOs:
1. ./print-iotdb-data-dir.sh <IoTDB数据文件夹路径，如果是多个文件夹用逗号分隔> (<输出结果的存储路径>)
注意：如果没有设置输出结果的存储路径, 将使用相对路径”IoTDB_data_dir_overview.txt”作为默认值。
示例
以Windows系统为例：
1. .\print-iotdb-data-dir.bat D:\github\master\iotdb\data\datanode\data
2. ````````````````````````
3. Starting Printing the IoTDB Data Directory Overview
4. ````````````````````````
5. output save path:IoTDB_data_dir_overview.txt
6. data dir num:1
7. 143 [main] WARN o.a.i.t.c.conf.TSFileDescriptor - not found iotdb-common.properties, use the default configs.

TsFile概览工具
TsFile概览工具用于以概要模式打印出一个TsFile的内容，工具位置为 tools/tsfile/print-tsfile。
用法
- Windows:
1. .\print-tsfile-sketch.bat <TsFile文件路径> (<输出结果的存储路径>)
- Linux or MacOs:
1. ./print-tsfile-sketch.sh <TsFile文件路径> (<输出结果的存储路径>)
注意：如果没有设置输出结果的存储路径, 将使用相对路径”TsFile_sketch_view.txt”作为默认值。
示例
以Windows系统为例：
1. .\print-tsfile.bat D:\github\master\1669359533965-1-0-0.tsfile D:\github\master\sketch.txt
2. ````````````````````````
3. Starting Printing the TsFile Sketch

解释：
- 以”|”为分隔，左边是在TsFile文件中的实际位置，右边是梗概内容。
- “|||||||||||||||||||||”是为增强可读性而添加的导引信息，不是TsFile中实际存储的数据。
- 最后打印的”IndexOfTimerseriesIndex Tree”是对TsFile文件末尾的元数据索引树的重新整理打印，便于直观理解，不是TsFile中存储的实际数据。
TsFile Resource概览工具
TsFile resource概览工具用于打印出TsFile resource文件的内容，工具位置为 tools/tsfile/print-tsfile-resource-files。
