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。
.\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>)
./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。
以Windows系统为例：
.\print-iotdb-data-dir.bat D:\github\master\iotdb\data\datanode\data ```````````````````````` Starting Printing the IoTDB Data Directory Overview ```````````````````````` output save path:IoTDB_data_dir_overview.txt data dir num:1 143 [main] WARN o.a.i.t.c.conf.TSFileDescriptor - not found iotdb-system.properties, use the default configs. |============================================================== |D:\github\master\iotdb\data\datanode\data |--sequence | |--root.redirect0 | | |--1 | | | |--0 | |--root.redirect1 | | |--2 | | | |--0 | |--root.redirect2 | | |--3 | | | |--0 | |--root.redirect3 | | |--4 | | | |--0 | |--root.redirect4 | | |--5 | | | |--0 | |--root.redirect5 | | |--6 | | | |--0 | |--root.sg1 | | |--0 | | | |--0 | | | |--2760 |--unsequence |==============================================================
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。
.\print-tsfile-sketch.bat <TsFile文件路径> (<输出结果的存储路径>)
./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。
