I am always headache with regex but guess it might be the way to do it. Here is the string I have:



-rw-rw----+  3 userabc clouderausersdev   12267543 2018-02-05 16:41 hdfs://nameservice1/client/abc/scenarios/warehouse/product/tdb_histscen_2/part-00000-6fa2e019-96e5-4280-b2fc-994917013a6a-c000.snappy.parquet


All I want to grep out is the file's full path:




hdfs://nameservice1/client/abc/scenarios/warehouse/product/tdb_histscen_2/part-00000-6fa2e019-96e5-4280-b2fc-994917013a6a-c000.snappy.parquet




Thank you very much.

Why not just take the last value of the space-separated string?



x = "-rw-rw----+  3 userabc clouderausersdev   12267543 2018-02-05 16:41 hdfs://nameservice1/client/abc/scenarios/warehouse/product/tdb_histscen_2/part-00000-6fa2e019-96e5-4280-b2fc-994917013a6a-c000.snappy.parquet"

parts = [y for y in x.split(' ') if y]  # removes empty strings

fname = parts[-1]

  • If your format is really fixed, as in an auto generated log file, this answer is probably easiest than using a length regex to fish out the path +1.
