Shell遍历目录文件的三种可靠方案：从for到find再到while read 在Linux、macOS、WSL及ADB Shell等终端环境中，遍历目录文件是自动化脚本开发的基础能力。其本质是通过路径名展开或流式枚举机制，将文件系统中的条目转化为可编程处理的数据流。技术价值在于消除重复操作、保障批量任务的健壮性与可移植性。典型应用场景包括Git Bash下批量重命名、zsh中安全清理临时文件、adb shell里授权安卓应用权限等。面对空格文件名、空目录、特殊字符等现实挑战，单纯依赖`for file in *`极易失效；而`find`凭借按需匹配与`-print0`支持，成为生产环阅读详情

1。本人想做一下一个可以用来杀毒的小软件，由于没有什么好资料，想通过病毒库来杀毒，希望大家指点一下，要怎么做的！
2。本人也想要一些处理注册表的代码，提供者有分！
3。如果有关于DELPHI编的杀毒软件源码本人也想要的，分不够再加！
希望大家帮忙！谢谢了！

常见的linux命令、shell命令、adb命令。 Shell 是你和 Linux 对话的 “翻译官”Shell 命令分两种：内置命令：Shell 自己带的（等）。普通命令：就是上面的 Linux 命令，Shell 帮你调用。所以：Linux 命令 ≈ 可以在 Shell 里运行的工具；Shell 命令 = Shell 内置 + 调用 Linux 命令。阅读详情

大家还是不明白我的意思
“一个递归搜索系统的文件和文件夹，并将指定的文件名或文件夹名删除
我要的是搜索与删除一起用的，当找到指定的文件就把它删除！
如果上面的朋友编的哪样的，我都　有的，就是我要把搜索与删除一起用的
我调试不出来的

！！
