Match from string

Match information is returned in the object

 $ echo '"Alice"' | jq 'match("A")' { "offset": 0, "length": 1, "string": "A", "captures": [] } 

Output matching character

 $ echo '"Alice"' | jq 'match("A").string' "A" $ echo '"Alice"' | jq 'match("(A)")' { "offset": 0, "length": 1, "string": "A", "captures": [ { "offset": 0, "length": 1, "string": "A", "name": null } ] } 

To capture

 $ echo '“Alice”' | jq 'match(“(A)(l)(i)(c)(e)“)' { “offset”: 0, “length”: 5, “string”: “Alice”, “captures”: [ { “offset”: 0, “length”: 1, “string”: “A”, “name”: null }, { “offset”: 1, “length”: 1, “string”: “l”, “name”: null }, { “offset”: 2, “length”: 1, “string”: “i”, “name”: null }, { “offset”: 3, “length”: 1, “string”: “c”, “name”: null }, { “offset”: 4, “length”: 1, “string”: “e”, “name”: null } ] } 

Captured string

 $ echo '“Alice”' | jq 'match(“(A)(l)(i)(c)(e)“).captures[].string' “A” “l” “i” “c” “e” 

Named Captcha

(An especially meaningless example)

 $ echo '“Alice”' | jq 'match(“(?<first_letter>A)(l)(i)(c)(e)“).captures[].name' “first_letter” null null null null
