Using csh & tcsh

If you use UNIX, you probably use csh to type commands even if you've never heard of it. It's the standard shell (command line) on most UNIX systems. tcsh is an enhanced version that's freely available and highly recommended.

Using csh & tcsh describes from the beginning how to use these shells interactively. More important, it shows how to get your work done faster with less typing. Even if you've used UNIX for years, techniques described in this book can make you more efficient.

You'll learn how to:

• Make your prompt tell you where you are (no more pwd)
  


• Use what you've typed before (history)
  


• Type long command lines with very few keystrokes (command and filename completion)
  


• Remind yourself of filenames when in the middle of typing a command
  


• Edit a botched command instead of retyping it

This book does not cover programming or script writing in csh or
tcsh because the tasks are better done with a different shell, such as sh (the Bourne shell) or a language like Perl.

如果你使用UNIX系統，即使你從未聽說過，你可能也會使用csh來輸入命令。它是大多數UNIX系統上的標準shell（命令行）。tcsh是一個增強版，可以免費獲得並且強烈推薦使用。

《使用csh和tcsh》從頭開始介紹了如何與這些shell進行互動。更重要的是，它展示了如何以更少的輸入更快地完成工作。即使你已經使用UNIX多年，本書中描述的技巧也可以讓你更高效。

你將學到如何：
- 讓提示符告訴你所在的位置（不再需要pwd）
- 使用之前輸入的內容（歷史記錄）
- 用很少的按鍵輸入長命令行（命令和文件名自動完成）
- 在輸入命令時提醒自己文件名
- 編輯錯誤的命令而不需要重新輸入

本書不涵蓋在csh或tcsh中進行編程或腳本編寫，因為這些任務最好使用不同的shell，例如sh（Bourne shell）或像Perl這樣的語言。
