less命令: opposite of more 文本文件阅读器,类似于more。

语法: less file
阅读器说明:
支持前后翻页查看文件。
k:向上移动一行
j:向下移动一行
space:向后翻页
b : 向前翻页
q:退出程序,不按此键,文本到达末尾也不会退出。
/:查找(n:向下查找,N:向上查找)

说明:less 就是man程序用的文本查看器,比较好用,比more好用,并且效率比较高,所以建议使用此预览器。
### Docker Buildx Build Command Usage and Options The `docker buildx build` command is an extended version of the standard `docker build` command that leverages advanced features provided by BuildKit[^1]. It allows users to perform builds with enhanced functionalities such as multi-platform image creation. Below are details about its usage, options, and examples: #### Basic Syntax ```bash docker buildx build [OPTIONS] PATH | URL | - ``` Here’s a breakdown of commonly used options for this command: - **--platform**: Specifies target platforms (e.g., linux/amd64, linux/arm64). This option enables cross-compilation across different architectures. Example: ```bash docker buildx build --platform=linux/amd64,linux/arm64 . ``` - **-t/--tag**: Tags the resulting image(s). Example: ```bash docker buildx build -t myimage:v1 . ``` - **--push**: Automatically pushes built images to registries after completion. Requires proper authentication setup beforehand. Example: ```bash docker buildx build --push -t username/myrepo:latest . ``` - **--load**: Loads the final image into the local daemon instead of exporting it directly when using multiple platforms or remote builders. Note that loading may not be supported in all scenarios involving distributed nodes. Example: ```bash docker buildx build --load -t mylocalimage:v1 . ``` - **--no-cache**: Disables caching during the build process which can speed up development cycles but might increase overall runtime depending upon circumstances like network latency etcetera. Example: ```bash docker buildx build --no-cache -t nocacheexample:v1 . ``` - **--progress**: Controls how progress information gets displayed; possible values include plain(default), tty(auto-detected based on terminal type) & quiet(no output except errors/warnings). Example: ```bash docker buildx build --progress=tty -t examplewithtty:v1 . ``` Additionally, there exist other less frequently utilized parameters too e.g.: –pull(always fetch latest base layers even if cached locally); –secret(pass sensitive data securely within context without exposing them inside container filesystems). For Linux environments where BuildX isn't pre-installed unlike Windows/MacOS counterparts[^2], one must manually set it up following procedures outlined previously including downloading appropriate binaries according specific system architecture requirements then placing those files correctly under user home directory structure at location "~/.docker/cli-plugins/" ensuring executable permissions granted appropriately via chmod commands before invoking any associated subcommands related specifically towards utilizing these newly added tools effectively thereafter.[^3] Finally here's sample code snippet demonstrating practical application incorporating several mentioned flags together simultaneously while performing actual operation against hypothetical source project folder named 'myproject': ```bash mkdir ~/myproject && c
