jc.parsers.sysctl

jc - JSON CLI output utility sysctl -a command output parser

Note: Since sysctl output is not easily parsable only a very simple key/value object will be output. An attempt is made to convert obvious integers and floats. If no conversion is desired, use the -r command-line argument or the raw=True argument in parse().

Usage (cli):

$ sysctl -a | jc --sysctl

or

$ jc sysctl -a

Usage (module):

import jc.parsers.sysctl
result = jc.parsers.sysctl.parse(sysctl_command_output)

Schema:

{
  "key1":     string/integer/float,         # best guess based on value
  "key2":     string/integer/float,
  "key3":     string/integer/float
}

Examples:

$ sysctl -a | jc --sysctl -p
{
  "user.cs_path": "/usr/bin:/bin:/usr/sbin:/sbin",
  "user.bc_base_max": 99,
  "user.bc_dim_max": 2048,
  "user.bc_scale_max": 99,
  "user.bc_string_max": 1000,
  "user.coll_weights_max": 2,
  "user.expr_nest_max": 32
  ...
}

$ sysctl -a | jc --sysctl -p -r
{
  "user.cs_path": "/usr/bin:/bin:/usr/sbin:/sbin",
  "user.bc_base_max": "99",
  "user.bc_dim_max": "2048",
  "user.bc_scale_max": "99",
  "user.bc_string_max": "1000",
  "user.coll_weights_max": "2",
  "user.expr_nest_max": "32",
  ...
}
