Eu quero estender o seguinte filtro:

$ jq -r '.[]|[.id, .login, ( if .groups == null then "n/a" else ([.groups[].name]|join("|")) end )]|@tsv' /tmp/test__
1e9b2215-9efd-67cc-9113-1e21c74f09d3    u0159   n/a
1e9b2215-9efd-67cc-9113-2b21c74f09d3    u0154   Default ABC|AGE
1e9b2215-9c2b-64f4-a0f1-47abdab7ae5f    u0155   ZZZ|Default ABC|NTE

para se livrar de todos os "ABC padrão" da lista de grupos separados por | na saída

Eu tentei com if adicional, mas ele falha com erro:

$ jq -r '.[]|[.id, .login, ( if .groups == null then "n/a" else ( if .groups[].name != "Default ABC" then [.groups[].name]|join("|")) end ) end )]|@tsv' /tmp/test__
jq: error: syntax error, unexpected ')' (Unix shell quoting issues?) at <top-level>, line 1:

agradeço qualquer dica...

a saída esperada para o json de amostra é:

1e9b2215-9efd-67cc-9113-1e21c74f09d3    u0159   n/a
1e9b2215-9efd-67cc-9113-2b21c74f09d3    u0154   AGE
1e9b2215-9c2b-64f4-a0f1-47abdab7ae5f    u0155   ZZZ|NTE

Atualização: Solução fornecida pela oliv:

$ jq -r '.[]|[.id,.login,if .groups then (.groups|map(select(.name != "Default ABC").name)|join("|")) else "n/a" end]|@tsv' /tmp/test__
1e9b2215-9efd-67cc-9113-1e21c74f09d3    u0159   n/a
1e9b2215-9efd-67cc-9113-2b21c74f09d3    u0154   AGE
1e9b2215-9c2b-64f4-a0f1-47abdab7ae5f    u0155   ZZZ|NTE
