关于>&2、2>&1等重定向的详细解释,基础教程网

关于>&2、2>&1等重定向的详细解释,基础教程网: "在POSIX shell中，命令的结果可以通过%>的形式来定义（其中%表示文件描述符：1为标准输出stdout、2为标准错误stderr）！系统默认%值是1，也就是1>，而1>可以简写为>，也就是默认为>。而stdout的默认目标是终端（这点不用验证吧）。另外，stderr的默认目标我个人认为也是终端，比如：
#abcddcba
sh: abcddcba: not found.
错误信息显示在终端上（对于telnet、dtterm等，那就说虚拟终端了）。"

shell 编程之2>&1_一树寒梅白玉条，迥临村路傍溪桥

shell 编程之2>&1_一树寒梅白玉条，迥临村路傍溪桥: "下面通过一个例子来展示2>&1有什么作用：
$ cat test.sh
t
date

test.sh中包含两个命令，其中t是一个不存在的命令，执行会报错，默认情况下，错误会输出到stderr。date则能正确执行，并且输出时间信息，默认输出到stdout
./test.sh > test1.log
./test.sh: line 1: t: command not found

$ cat test1.log
Tue Oct 9 20:51:50 CST 2007

可以看到，date的执行结果被重定向到log文件中了，而t无法执行的错误则只打印在屏幕上。
$ ./test.sh > test2.log 2>&1

$ cat test2.log
./test.sh: line 1: t: command not found
Tue Oct 9 20:53:44 CST 2007

这次，stderr和stdout的内容都被重定向到log文件中了。"

* 2>&1 就是将 stderr 并进 stdout 作输出
* 1>&2 或 >&2 就是将 stdout 并进 stderr 作输出

2.4 Special Keys

2.4 Special Keys: "Chapter 2: Getting Started on a UNIX System
2.4 Special Keys

Like all systems, UNIX has a number"

Name	Control Char	Function
erase	DEL or backspace	Erase character. Backspace and erase one character (the key used depends on terminal setting). Sometimes, especially within tcl/tk applications, you must use .
werase		Delete the rightmost word typed in.
kill		Kill (erase) the line typed in so far.[8]
intr		Interrupt the program currently running.
rprnt		Reprint the line typed in so far.
flush		Stops terminal output until you press a key.
susp		Suspend the program currently running and put it in the background. This does not stop the process as it does in VMS!
stop		Stop the display. To resume, press the start key
start		Start the display after stop.
eof		Send the program an end-of-file character.

CS385 Homework Assignment 1a
Subject: customize shell environment start up configuration file(s)
Due Date: Mar. 4, 2008

A. Study and understand each entry in the ".cshrc" and ".tcshrc" (if applicable) under your UNIX home directory on NPU's Sun workstation systems
B. COPY /cs385/.cshrc.base as your template and refer sample files ".cshrc.sample" and ".tcshrc.sample" under /cs385 on NPU48 (ONLY on NPU48!)
C. Polish your VI editing skill, make sure you are comfortable with cursor movement and vi commands
D. Create a duplicate of your current ".cshrc" file; Open 2nd connection to NPU48; edit ".cshrc" with VI:
i. Clean up unwanted and obsoleted entries such as lpath, extra aliases and comment-out lines
ii. Correct environment variables as appropriate, in particular, PATH, MANPATH, most importatnt function keys such as ERASE, INTERRUPT, STOP, SUSPEND, EOF and KILL; creat your favoriate aliases; add variable such as tabs, umask, filec, tty, noclobber, and history et al. set your prompt so it will display (minimum the following) your login-name, hostname (system name) and current working directory.
iii. Save your changes; execute command "source ~/.cshrc" or equivalent(.) in other shell to configure the file
iv. if no error after execution, you are ok; otherwise, repeate steps i through iii until no error
v. customize your .bash_profile in a way similar to above for .cshrc
E. Turn in a hard copy of your customzied ".cshrc" and ".bash_profile" file plus a soft copy to NPU48:/cs385/hmwk/hmwk-1 with a unique name such as "your-unix-login-name.cshrc" and "your-unix-login-name.bash_profile"

F. These who copy AND allow-others-to-copy their homework will get NULL for sure.

======Optional Bonus Questions ======
locate the ssh program embeded finger-print file for security keies on your Windows desktop


when finish:
1.soft.copy-> npu48: /cs385/hmwk/hmwk-1 with unique name.
2.hand.copy-> TA.
