重定向输入mongo脚本:
#! /bin/bash mongo --username root --password 123456 --host 10.10.10.10 --port 27017 --authenticationDatabase admin <<EOF use apple; db.currentOp(); EOF
转义$:
shell中使用mongodb的时候,如果需要查询条件$,则需要转义$,因为$字符在shell中是变量的意思:
#! /bin/bash mongo --username root --password 123456 --host 10.10.10.10 --port 27017 --authenticationDatabase admin <<EOF use apple; print("该实例上的连接数情况:db.serverStatus().connections;"); db.serverStatus().connections; print("==========================="); db.currentOp({ "desc" :{\$nin: ["rsSync-0","ReplBatcher","monitoring keys for HMAC","WT OplogTruncaterThread: local.oplog.rs","NoopWriter"]}}); EOF
