Overview

"csv" assumes that the input file or piped content is text comma-separated content and parses it, generating events, which then are further processed depending on the command specified on command line.

csv [command] [query] <input-file.csv>

The default command, which does not need to be specified is output: the CSV content is parsed and the resulted events are displayed at stdout:

csv [query] [-o output-spec] <input-file.csv>

Usage on pipes:

tail -f input.csv | csv [command] [query]

headers

Scan the CSV stream and display the headers, as they are identified in the stream. The command displays the number of the line on which the header is found, and then, for each header:

  • the index that can be used to access the value that corresponds the header in a data lines. The index can be used for index-based output
  • the header name
  • the header type
  • optionally, the header format
csv headers ./sample.csv

line 1 header:
  1: timestamp(time:MM/dd/yy HH:mm:ss)
  2: CPU User Time(string)
  3: CPU Kernel Time(string)
  4: CPU I/O Wait Time(string)
