核心工具 是 GNU/Linux 系统基本、基础的工具。本文提供对它们不完整的概览、链接文档并描述有用的替代品。本文的范围包括，但不限于 GNU coreutils。大多数核心工具都是传统的 Unix 工具，它们中的许多已由 POSIX 标准化，但已进一步发展，从而提供更多功能。

大多数命令行界面的文档都在 man page 中，来自 GNU 项目 的工具的文档主要在 Info manual 中，一些 shell 为内置命令提供了 help 命令。另外，大多数命令在使用 --help 标志运行时会显示自身的使用说明。

基础[编辑 | 编辑源代码]

下表列出了一些 Arch Linux 用户应当熟悉的重要的工具。另请参见 intro(1)。

防止数据损失[编辑 | 编辑源代码]

rm、mv、cp 和 shell 重定向无需确认即可删除或覆盖文件。rm、mv 和 cp 都支持 -i 标志以在删除/覆盖前提醒用户。一些用户喜欢通过 alias 默认启用 -i。依赖这些 shell 选项可能很危险，因为你会习惯于它们，从而在你使用没有它们的系统或用户时导致潜在的数据损失。防止数据损失的最好办法是创建备份。

dd alternatives[编辑 | 编辑源代码]

Tango-view-fullscreen.png这篇文章的某些内容需要扩充。Tango-view-fullscreen.png

原因： ddrescue should be added to a list below and briefly described. Given the name similarity, it would be nice to mention the differences from dd_rescue. (在 Talk:核心工具 中讨论)

Alternative dd implementations[编辑 | 编辑源代码]

This subsection lists dd implementations whose interface and default behaviour is mostly compliant with the POSIX specification of dd(1p).

  • ddpt — A portable rewrite of sg_dd(8) by the SCSI subsystem maintainer of the Linux kernel, with optional but very specialised hardware I/O (SCSI command sets) support, plus many other features.
http://sg.danny.cz/sg/ddpt.html || ddptAUR
  • sdd — A dd implementation portable across UNIX environments by Joerg Schilling, that can checksum the copied data and retry reading bad blocks.
https://schilytools.sourceforge.net/ || schily-tools-sddAUR
Spin-offs of GNU dd[编辑 | 编辑源代码]

The GNU implementation of dd found in coreutils包 also conforms to POSIX. This subsection lists its forks.

  • dcfldd — feature-enhanced fork of GNU dd for forensics and security scenarios, includes on-the-fly hashing capability, flexible wipes, write verification, output to multiple targets at the same time, split and piped output.
http://dcfldd.sourceforge.net || dcflddAUR
  • dc3dd — Another patched version of GNU dd from the United States Department of Defense Cyber Crime Center (DC3), with similar goals and features to dcfldd.
https://sourceforge.net/projects/dc3dd/ || dc3ddAUR

Modernised dd analogues[编辑 | 编辑源代码]

This subsection lists dd alternatives that do not conform to POSIX (in terms of the JCL-resembling command-line syntax and default behaviour).

  • dd_rescue — A feature-packed, modernised dd analogue that is suitable for daily scripting, disk cloning, and data recovery.
http://www.garloff.de/kurt/linux/ddrescue/ || dd_rescue包

https://sortix.org/rw/ || rwAUR

buffer spin-offs[编辑 | 编辑源代码]
