1.如何求助？起手式 ， 核心的一点是寻求帮助 。 choco与正常的linux命令查询大相径庭 。
比如scoop的查询是这样的：
PS C:\Users\gaowei\Videos\BibleProject> scoop help updateUsage: scoop update[options]'scoop update' updates Scoop to the latest version.'scoop update ' installs a new version of that app, if there is one.You can use '*' in place ofto update all apps.Options:-f, --forceForce update even when there isn't a newer version-g, --globalUpdate a globally installed app-i, --independentDon't install dependencies automatically-k, --no-cacheDon't use the download cache-s, --skipSkip hash validation (use with caution!)-q, --quietHide extraneous messages但是choco却将help放置在了后面 ， 而且还是single-dash ， 既然如此也便只能“客随主便”了 。
PS C:\Users\gaowei\Videos\BibleProject> choco list -helpChocolatey v0.10.15List/Search CommandChocolatey will perform a search for a package local or remote. Some may prefer to use `clist` as a shortcut for `choco list`. 2.安装软件安装案例如下：
choco install sysinternalschoco install notepadplusplus googlechrome atom 7zipchoco install notepadplusplus --force --force-dependencieschoco install notepadplusplus googlechrome atom 7zip -dvfychoco install git -y --params="'/GitAndUnixToolsOnPath /NoAutoCrlf'"choco install git -y --params="'/GitAndUnixToolsOnPath /NoAutoCrlf'" --install-arguments="'/DIR=C:\git'"# Params are package parameters, passed to the package# Install args are installer arguments, appended to the silentArgs#in the package for the installer itselfchoco install nodejs.install --version 0.10.35choco install git -s "'https://somewhere/out/there'"choco install git -s "'https://somewhere/protected'" -u user -p pass3.查阅已安装的软件【用Choco安装和管理windows应用程序的八项高频操作】查阅已安装的软件 ， 不能直接输入命令：
PS C:\Users\gaowei\Videos\BibleProject> choco listChocolatey v0.10.15系统会始终处于pending的状态 。 解决方案必须加上options：
choco list --local-onlychoco list -lichoco list -laichoco list --page=0 --page-size=25choco search gitchoco search git --source="'https://somewhere/out/there'"choco search bob -s "'https://somewhere/protected'" -u user -p pass4.列出所有过期的软件升级apps前 ， 先检查是否已经过期 。
PS C:\Users\gaowei\scoop\apps\scoop\current> choco outdatedChocolatey v0.10.15Outdated Packages Output is package name | current version | available version | pinned?adobereader|2020.012.20043|2020.012.20048|falsecalibre|4.23.0|5.3.0|falsedotnetcore3-desktop-runtime|3.1.8|3.1.9|falseKB2533623|1.0.4|2.0.0|falsemicrosoft-edge|84.0.522.63|86.0.622.56|falsepowertoys|0.21.1|0.25.0|falsevcredist140|14.26.28720.3|14.27.29112|falsevisualstudio2017buildtools|15.9.26.0|15.9.28.0|false5.升级软件升级全部的安装程序：
