I can get top-level JSON keys with jq
as
jq 'keys'
Eg, see this question: Get key names from JSON file using jq
And I can enable recursion in jq
:
jq '..'
As in: Recursive search values by key
But jq '.. | keys'
jq '.. | keys'
returns jq: error at <stdin> string has no keys
.
当 JSON 中的某些值不存在键时,只需忽略键:
jq '.. | keys?'
Ignore non-objects when inspecting for key names:
jq -r '.. | if type == "object" then to_entries[] | .key else empty end' "${LOCALAPPDATA}/Google/Chrome/User Data/default/Bookmarks" | sort --uniq
bookmark_bar
checksum
children
date_added
date_modified
guid
id
name
other
roots
synced
type
url
version
