Question

想要通过编号desc或asc订购“usedsize”列。

输入：

{"name":"db1","tablespace":"TEMP","size":"1000","maxsize":"65536","usedsize":"21","status":0.03},
{"name":"db1","tablespace":"DAT","size":"360612","maxsize":"475680","usedsize":"360321","status":75.75},
{"name":"db1","tablespace":"CUNBDAT","size":"23800","maxsize":"131072","usedsize":"23694","status":18.08},

我尝试使用分隔符和coulmn行，但似乎有些错误：

sort -t: -k10

预期观点：

{"name":"db1","tablespace":"DAT","size":"360612","maxsize":"475680","usedsize":"360321","status":75.75},
{"name":"db1","tablespace":"CUNBDAT","size":"23800","maxsize":"131072","usedsize":"23694","status":18.08},
{"name":"db1","tablespace":"TEMP","size":"1000","maxsize":"65536","usedsize":"21","status":0.03},

Answer 1

这不是第10列，而是第6列：

$ sort -t: -k6 file
{"name":"db1","tablespace":"TEMP","size":"1000","maxsize":"65536","usedsize":"21","status":0.03},
{"name":"db1","tablespace":"CUNBDAT","size":"23800","maxsize":"131072","usedsize":"23694","status":18.08},
{"name":"db1","tablespace":"DAT","size":"360612","maxsize":"475680","usedsize":"360321","status":75.75}

Answer 2

你可以说

sort -t, -k5,5r filename

如果您按下输入以使其成为有效的JSON，您可以使用perl：

perl -MJSON -00 -le '
    $data = decode_json(<>);
    print encode_json([sort {$b->{usedsize} <=> $a->{usedsize}} @$data]);
' <<END
[
{"name":"db1","tablespace":"TEMP","size":"1000","maxsize":"65536","usedsize":"21","status":0.03},
{"name":"db1","tablespace":"DAT","size":"360612","maxsize":"475680","usedsize":"360321","status":75.75},
{"name":"db1","tablespace":"CUNBDAT","size":"23800","maxsize":"131072","usedsize":"23694","status":18.08}
]
END

[{ “状态”：75.75， “姓名”： “DB1”， “usedsize”： “360321”， “MAXSIZE”： “475680”， “大小”： “360612”， “表”： “DAT” }，{ “地位”：18.08， “名”： “DB1”， “usedsize”： “23694”， “最大范围”： “131072”， “大小”： “23800”， “表”： “CUNBDAT”}， { “状态”：0.03， “姓名”： “DB1”， “usedsize”： “21”， “MAXSIZE”： “65536”， “大小”： “1000”， “表”： “TEMP”}]
