About jq
’s --slurp
option
Problem: you want to find the unique values of a key in some
JSON Lines input using
jq
.
JQ’s unique
function requires an array as input and so we must convert the
separate JSON objects from the JSONL steam into an array. This is done using the
--slurp
option:

Example usage:
# Find unique workspace names
$ cat workspaces.jsonl | jq --slurp '[.[].workspace_name] | unique'
where [.[].workspace_name]
creates an array of all .workspace_name
keys from
each object in the JSONL stream.
