recs-fromsplit --help-all

Help from: --help-basic:
Usage: recs-fromsplit <args> [<files>]
   Each line of input (or lines of <files>) is split on provided delimiter to produce an output record. Keys are named numerically (0, 1, etc.) or as given by --key.

Arguments:
   --delim|-d <delim>           Delimiter to use for splitting input lines (default
   --key|-k <key>               Comma separated list of key names. May be specified multiple times, may be key specs
   --header                     Take key names from the first line of input.
   --strict                     Delimiter is not treated as a regex
   --filename-key|fk <keyspec>  Add a key with the source filename (if no filename is applicable will put NONE)

  Help Options:
      --help-all       Output all help for this script
      --help           This help screen
      --help-keyspecs  Help on keyspecs, a way to index deeply and with regexes

Examples:
   Parse space separated keys x and y.
      recs-fromsplit --key x,y --delim ' '
   Parse comma separated keys a, b, and c.
      recs-fromsplit --key a,b,c

Help from: --help-keyspecs:
KEY SPECS   
   A key spec is short way of specifying a field with prefixes or regular expressions, it may also be nested into hashes and arrays. Use a '/' to nest into a hash and a '#NUM' to index into an array (i.e. #2)

   An example is in order, take a record like this:
   
     {"biz":["a","b","c"],"foo":{"bar 1":1},"zap":"blah1"}
     {"biz":["a","b","c"],"foo":{"bar 1":2},"zap":"blah2"}
     {"biz":["a","b","c"],"foo":{"bar 1":3},"zap":"blah3"}
   
   In this case a key spec of 'foo/bar 1' would have the values 1,2, and 3 in the respective records.

   Similarly, 'biz/#0' would have the value of 'a' for all 3 records

   You can also prefix key specs with '@' to engage the fuzzy matching logic
   
   Fuzzy matching works like this in order, first key to match wins
     1. Exact match ( eq )
     2. Prefix match ( m/^/ )
     3. Match anywehre in the key (m//)
   
   So, in the above example '@b/#2', the 'b' portion would expand to 'biz' and 2 would be the index into the array, so all records would have the value of 'c'

   Simiarly, @f/b would have values 1, 2, and 3

   You can escape / with a \. For example, if you have a record:
   {"foo/bar":2}

   You can address that key with foo\/bar
