Linux与Windows系统下jq 1.7命令执行行为差异及报错求助

问题根源是Windows命令提示符（CMD）和PowerShell的引号解析规则与Linux Bash不同，导致jq过滤器被拆分成了多个无效命令。以下是针对两种Windows环境的适配方案：

1. Windows命令提示符（CMD）适配命令 #

CMD仅识别双引号作为字符串边界，且内部双引号需要用\"转义，将整个jq过滤器用双引号包裹，确保参数完整传递：

aws dms describe-replication-tasks --filter Name=replication-task-id,Values=TASKNAME --output json | jq ".ReplicationTasks | .[] | .TableMappings |= fromjson | .ReplicationTaskSettings |= fromjson | delpaths([ [\"ReplicationTaskArn\"],[\"ReplicationTaskStartDate\"],[\"ReplicationTaskStats\"],[\"Status\"],[\"StopReason\"],[\"ReplicationTaskCreationDate\"],[\"ReplicationTaskSettings\",\"Logging\",\"CloudWatchLogGroup\"],[\"ReplicationTaskSettings\",\"Logging\",\"CloudWatchLogStream\"],[\"RecoveryCheckpoint\"]]) | .TableMappings |= tostring | .ReplicationTaskSettings |= tostring" > TASKNAME.json

2. PowerShell适配命令 #

PowerShell支持单引号作为"原样字符串"，内部特殊字符不会被解析，直接将原Linux命令的jq过滤器用单引号包裹即可：

aws dms describe-replication-tasks --filter Name=replication-task-id,Values=TASKNAME --output json | jq '.ReplicationTasks | .[] | .TableMappings |= fromjson | .ReplicationTaskSettings |= fromjson | delpaths([ ["ReplicationTaskArn"],["ReplicationTaskStartDate"],["ReplicationTaskStats"],["Status"],["StopReason"],["ReplicationTaskCreationDate"],["ReplicationTaskSettings","Logging","CloudWatchLogGroup"],["ReplicationTaskSettings","Logging","CloudWatchLogStream"],["RecoveryCheckpoint"]]) | .TableMappings |= tostring | .ReplicationTaskSettings |= tostring' > TASKNAME.json

通用简化方案（跨环境兼容） #

如果过滤器逻辑复杂，可将jq规则保存为单独文件（比如filter.jq），避免引号适配问题：
filter.jq内容：

.ReplicationTasks | .[] | .TableMappings |= fromjson | .ReplicationTaskSettings |= fromjson | delpaths([ ["ReplicationTaskArn"],["ReplicationTaskStartDate"],["ReplicationTaskStats"],["Status"],["StopReason"],["ReplicationTaskCreationDate"],["ReplicationTaskSettings","Logging","CloudWatchLogGroup"],["ReplicationTaskSettings","Logging","CloudWatchLogStream"],["RecoveryCheckpoint"]]) | .TableMappings |= tostring | .ReplicationTaskSettings |= tostring

然后在CMD/PowerShell/Linux中统一执行：

aws dms describe-replication-tasks --filter Name=replication-task-id,Values=TASKNAME --output json | jq -f filter.jq > TASKNAME.json
