我有一个类似下面例子的JSON字符串,我想在shell脚本中使用"uptime"命令的值作为变量,该怎么办?
注:此问题已被其他人提问,您可以查看这里。{ "serverStatus" : { "version" : "1.6.0", "uptime" : 527, "uptimeEstimate" : 526, "localTime" : { "$date" : 1286923624579 }, "globalLock" : { "totalTime" : 526604302, "lockTime" : 3499842, "ratio" : 0.006646056605895331, "currentQueue" : { "total" : 0, "readers" : 0, "writers" : 0 } }, "mem" : { "bits" : 64, "resident" : 150, "virtual" : 76114, "supported" : true, "mapped" : 75950 }, "connections" : { "current" : 1, "available" : 9599 }, "extra_info" : { "note" : "fields vary by platform", "heap_usage_bytes" : 600592, "page_faults" : 1838 }, "indexCounters"....
