在 package.json 中使用 shx 删除和复制文件
delete and copy files using shx in package.json
我有两个 npm 项目，一个是名为 server-project 的 Gatsby project called web-project and another one is Express 项目。
这是项目的文件结构：
- projects
- web-project
- public
- package.json
- server-project
- package.json
- public
如果我 运行 在 web-project/package.json 中命令 npm run build，我想为 Web 项目生成构建文件，删除文件夹 server-project/public 中的内容并从中复制内容web-project/public 到 server-project/public.
我尝试使用 shx，它在 web-project 本地安装，但它不起作用。 Gatsby 生成构建文件，但 shx 不复制它们。
web-project/package.json
"scripts": {
"build": "gatsby build && (shx find ../server-project/public -type f -delete && shx cp -R public/* ../server-project/public)"
...
},

您可以从 shx cp -R public/* ../server-project/public 中删除通配符，因为递归标志将选取源目录中的所有内容。这应该让你得到你想要的 -
shx cp -R public ../server-project/public
您似乎已经在构建系统中使用了 find。我利用 tar 并在我维护的一些构建系统中找到了大量内容，这对我来说效果很好。 tar 可以很好地处理各种边缘情况，因为它最初是作为备份实用程序编写的。
在tar中，-是表示stdin或stdout的文件名，-T指定要备份的文件列表，-C指定其工作目录。这使您可以将一堆东西与管道粘合在一起，并完成一些非常酷的事情。例如，
(cd /path/to/src/files && find . -type f -name) \
| tar -T - -cf - \
| tar -C /path/to/dest -xvf -
- 子 shell 让我在不影响其他命令的情况下查找目录
- find 在 stdout 上生成文件列表
- 第一个 tar 读取要归档到标准输入的文件列表
- 第一个 tar 在 stdout
上生成存档
- 第二个 tar 将目录更改为 /path/to/dest
- 然后它在 stdin
上提取存档
- 和 'v' 打印提取的文件列表
这将为您保留所有权、组成员资格、权限、符号链接、目录结构，整个九码。即使是带空格的文件名也不会搞砸。 :)
这部分存在的主要问题：
shx find ../server-project/public -type f -delete
-type f 标志在 shx 中不受支持（参见 issue #177）。据推测，-delete 标志也不被支持。
考虑用执行以下操作的 node.js 脚本替换该部分：
例如，将其全部放入名为 build:
的单个 npm 脚本中
"scripts": {
...
"build": "gatsby build && node -e \"var sh = require('shelljs'), fs = require('fs'); sh.find('../server-project/public').forEach(function (file) { if (!fs.statSync(file).isDirectory()) { sh.rm(file); }});\" && shx cp -R \"public\" \"../server-project/public\""
...
}
备注：
您在 OP 中尝试使用 find ../server-project/public -type f -delete 意味着您的意图是（仅）从 ../server-project/public 中删除所有文件（n 级深）- 但不要删除 ../server-project/public 中的任何文件夹（再次 n 级深）。这就是上述示例中的 node -e \"...\" 命令复制的内容。
nodejs命令行选项-e用于评估内联Javascript，本质上是这样的：
var sh = require('shelljs'),
fs = require('fs');
sh.find('../server-project/public').forEach(function (file) {
if (!fs.statSync(file).isDirectory()) {
sh.rm(file);
}
});
如您所见，使用 Logical NOT (!) operator, the fs.statSync method and isDirectory() 的组合来确定路径名是否是文件而不是 directory/folder.
使用shelljsrm方法删除文件
最后一个 shx cp -R ... 命令中的 globstar (*) 和包含复合命令的括号 (...) 已被省略。
我有两个 npm 项目，一个是名为 server-project 的 Gatsby project called web-project and another one is Express 项目。
这是项目的文件结构：
- projects
- web-project
- public

- server-project

shx find ../server-project/public -type f -delete
-type f 标志在 shx 中不受支持（参见 issue #177）。据推测，-delete 标志也不被支持。
考虑用执行以下操作的 node.js 脚本替换该部分：
例如，将其全部放入名为 build:
"scripts": {
...
"build": "gatsby build && node -e \"var sh = require('shelljs'), fs = require('fs'); sh.find('../server-project/public').forEach(function (file) { if (!fs.statSync(file).isDirectory()) { sh.rm(file); }});\" && shx cp -R \"public\" \"../server-project/public\""
...
}
备注：
您在 OP 中尝试使用
find ../server-project/public -type f -delete意味着您的意图是（仅）从../server-project/public中删除所有文件（n 级深）- 但不要删除../server-project/public中的任何文件夹（再次 n 级深）。这就是上述示例中的node -e \"...\"命令复制的内容。nodejs命令行选项
-e用于评估内联Javascript，本质上是这样的：var sh = require('shelljs'), fs = require('fs'); sh.find('../server-project/public').forEach(function (file) { if (!fs.statSync(file).isDirectory()) { sh.rm(file); } });如您所见，使用 Logical NOT (
!) operator, thefs.statSyncmethod andisDirectory()的组合来确定路径名是否是文件而不是 directory/folder.使用shelljs
rm方法删除文件
最后一个
shx cp -R ...命令中的 globstar (*) 和包含复合命令的括号(...)已被省略。
