input json:
{
"id": "3885",
"login": "050111",
"lastLoginTime": 1529730115000,
"lastLoginFrom": "192.168.66.230"
}
{
"id": "3898",
"login": "050112",
"lastLoginTime": null,
"lastLoginFrom": null
}
I want to get output for login, lastLoginTime and lastLoginFrom in tabulator delimited format:
050111 1529730115000 192.168.66.230
050112 - -
with below jq filter I get on output no "null" values which I could replace with "-"
$ jq -r '.|[.login, .lastLoginTime, .lastLoginFrom]|@tsv' test_json
050111 1529730115000 192.168.66.230
050112
Is there any other way to get "-" printed for such null values?
