• curl,wget (for download and REST API)
• ping (for network stuff)

(*: via convertion) (**: via tidy )

jsonA means json array like :

[
	["head1", "head2", "head3"],
	["x=1 y=1", "x=2 y=1", "x=3 y=1",
	["x=1 y=2", "x=2 y=2", "x=3 y=2"
]

jsonO means json Object like :

[
	{"head1": "x=1 y=1", "head2": "x=2 y=1", "head3": "x=3 y=1"},
	{"head1": "x=1 y=2", "head2": "x=2 y=2", "head3": "x=3 y=2"}
]
