从路径列表中删除所有父目录
从路径列表中删除所有父目录
提问于 2018-10-19 16:28:52
我有一个bash命令，它列出了HDFS中以/random开头的目录。
其内容如下：
hdfs dfs -ls -R /random | grep '^d' | awk '{print $NF}'它生成以下输出：
/random/custom
/random/custom/hive
/random/custom/hive/jars
/random/app
/random/app/nifi
/random/app/nifi/egispub
/random/app/nifi/empgis
/random/app/nifi/ods
/random/app/nifi/ptcsm
/random/app/nifi/tmds
/random/app/nifi/ucmdb
/random/app/oozie
/random/app/oozie/efdm
/random/app/oozie/efdm/ensco
/random/app/oozie/efdm/ensco/standardized_efdm_ensco_parser_5min
/random/app/oozie/efdm/ensco/standardized_efdm_ensco_parser_5min/lib
/random/app/oozie/efdm/mermec
/random/app/oozie/efdm/mermec/cleansed_efdm_mermec_5min
/random/app/oozie/efdm/mermec/standardized_efdm_mermec_5min
/random/app/oozie/gis
/random/app/oozie/gis/opk
/random/app/oozie/gis/opk/standardized_gis_opk_parser_10min
/random/app/oozie/gis/opk/standardized_gis_opk_parser_10min/lib
/random/app/oozie/gis/opk/standardized_gis_opk_parser_10min/schemas我想修改我的命令，以便只列出完整的目录路径，如下所示：
/random/custom/hive/jars
/random/app/nifi/egispub
/random/app/nifi/empgis
/random/app/nifi/ods
/random/app/nifi/ptcsm
/random/app/nifi/tmds
/random/app/nifi/ucmdb
/random/app/oozie/efdm/ensco/standardized_efdm_ensco_parser_5min/lib
/random/app/oozie/efdm/mermec/cleansed_efdm_mermec_5min
/random/app/oozie/efdm/mermec/standardized_efdm_mermec_5min
/random/app/oozie/gis/opk/standardized_gis_opk_parser_10min/lib
/random/app/oozie/gis/opk/standardized_gis_opk_parser_10min/schemas你会怎么做？

你只想打印非目录文件？试着把你的结果看清楚
awk -F/ 'NF <= OLDNF {print LAST}; {OLDNF = NF; LAST = $0} END {print LAST}'
/random/custom/hive/jars
/random/app/nifi/egispub
/random/app/nifi/empgis
/random/app/nifi/ods
/random/app/nifi/ptcsm
/random/app/nifi/tmds
/random/app/nifi/ucmdb
/random/app/oozie/efdm/ensco/standardized_efdm_ensco_parser_5min/lib
/random/app/oozie/efdm/mermec/cleansed_efdm_mermec_5min
/random/app/oozie/efdm/mermec/standardized_efdm_mermec_5min
/random/app/oozie/gis/opk/standardized_gis_opk_parser_10min/lib
/random/app/oozie/gis/opk/standardized_gis_opk_parser_10min/schemas它查找读取路径的“增长深度”，并打印该路径是否缩小(返回到dir深度)或保持相等(文件位于同一层次)。
