Description

Command description

A command-line JSON viewer designed for reading, exploring, and searching through JSON data.

jless can handle newline-delimited JSON, so feel free to pipe in the output from jq or some dense log files.

jless has a large suite of vim-inspired commands. Commands prefixed by count may be preceded by a number N, which will perform a command a given number of times.
