SYNOPSIS
gron [options] [file]
DESCRIPTION
gron transforms JSON into discrete path-value assignments, making it greppable with standard Unix tools. Each JSON value becomes a single line showing its full path from the root.Results can be filtered with grep and converted back to valid JSON using ungron mode (-u), enabling powerful JSON querying without specialized tools.

HISTORY
gron was created by Tom Hudson to solve the problem of searching complex JSON structures with traditional Unix tools.
