scoop install cwgo get github.com/lucagrulla/cw--profile=profile-name覆盖用于连接的AWS配置文件。--region=aws-region覆盖目标AWS区域。--no-color禁用彩色输出。--endpoint目标AWS端点URL。默认情况下，CW将使用默认的AWS端点。--no-version-check忽略检查是否有新版本的模块可用。cw ls列出了组中的所有日志组/日志流
Usage: cw ls <command>
show an entity
Flags:
-h, --help Show context-sensitive help.
--endpoint=URL The target AWS endpoint url. By default cw will use the default aws endpoints. NOTE: v4.0.0

-f, --follow Don't stop when the end of streams is reached, but rather wait for additional data to be appended.
-t, --timestamp Print the event timestamp.
-i, --event-id Print the event Id.
-s, --stream-name Print the log stream name this event belongs to.

-q, --query=STRING Equivalent of the --query flag in AWS CLI. Takes a JMESPath expression to filter JSON logs by. If the query fails (e.g. the log message was not JSON) then the original line is returned. 可用日志组列表
cw ls groups给定日志组中的日志流列表
cw ls streams my-log-group尾巴并遵循给定的日志组/流
cw tail -f my-log-groupcw tail -f my-log-group:my-log-stream-prefixcw tail -f my-log-group:my-log-stream-prefix my-log-group2cw tail -f my-log-group:my-log-stream-prefix -b2017-01-01T08:10:10 -e2017-01-01T08:05:00cw tail -f my-log-group:my-log-stream-prefix -b7d从7天前开始。cw tail -f my-log-group:my-log-stream-prefix -b3h从3小时前开始。cw tail -f my-log-group:my-log-stream-prefix -b100m从100分钟前开始。cw tail -f my-log-group:my-log-stream-prefix -b2h30m从2小时30分钟开始。cw tail -f my-log-group -b9:00 -e9:01使用jmespath语法查询JSON日志
cw tail -f my-log-group --query "machines[?state=='running'].name"默认情况下，时间和日期被视为UTC。如果您喜欢使用本地区域，请使用--local标志。
cw使用默认凭据配置文件（存储在./aws/credentials中）进行身份验证和共享配置（.aws/config）来识别目标AWS区域。轮廓和区域都可以通过profile和region全局标志覆盖。
如果您可以支持AWS SSO：
default或替代命名配置文件）sso_start_url ， sso_account_id ， sso_role_name等aws sso login如果您收到一个错误消息，其中包括...failed to sign request: failed to retrieve credentials: the SSO session has expired or is invalid...那么您应该通过aws sso login续订SSO会话（如果适用，并指定命名配置文件，请指定）。
cw请根据AWS CLI的要求使用HTTP_PROXY环境变量：https：//docs.aws.amazon.com/cli/latest/userguide/cli-configure-proxy.html
