Linux最重要的软件之一就是shell，目前最流行的shell被称为Bash，几乎所有的Linux和绝大部分的UNIX都可以使用Bash。作为系统与用户之间的交互接口，shell几乎是你在Linux工作平台上最亲密的朋友，因此，学好shell，是学习Linux的关键，并且它会始终伴随你的工作学习。共同加油吧！

shell 是操作系统的最外层。shell 合并编程语言以控制进程和文件，以及启动和控制其它程序。shell 通过提示您输入，向操作系统解释该输入，然后处理来自操作系统的任何结果输出来管理您与操作系统之间的交互。
shell 向您提供了与操作系统通信的方式。此通信以交互的方式（来自键盘的输入立即操作）或作为一个 shell 脚本执行。shell 脚本是 shell 和操作系统命令的序列，它存储在文件中。

Shell脚本高级编程教程，希望对你有所帮助。
Example 10-23. Using continue N in an actual task：
1 # Albert Reiner gives an example of how to use "continue N":
2 # ---------------------------------------------------------
3
4 # Suppose I have a large number of jobs that need to be run, with
5 #+ any data that is to be treated in files of a given name pattern in a
6 #+ directory. There are several machines that access this directory, and
7 #+ I want to distribute the work over these different boxen. Then I
8 #+ usually nohup something like the following on every box:
9
10 while true
11 do
12 for n in .iso.*
13 do
14 [ "$n" = ".iso.opts" ] && continue
15 beta=${n#.iso.}
16 [ -r .Iso.$beta ] && continue
17 [ -r .lock.$beta ] && sleep 10 && continue
18 lockfile -r0 .lock.$beta || continue
19 echo -n "$beta: " `date`
20 run-isotherm $beta
21 date
22 ls -alF .Iso.$beta
23 [ -r .Iso.$beta ] && rm -f .lock.$beta
24 continue 2
25 done
26 break
27 done
28
29 # The details, in particular the sleep N, are particular to my
30 #+ application, but the general pattern is:
31
32 while true
33 do
34 for job in {pattern}
35 do
36 {job already done or running} && continue
37 {mark job as running, do job, mark job as done}
38 continue 2
39 done
40 break # Or something like `sleep 600' to avoid termination.
41 done
42
43 # This way the script will stop only when there are no more jobs to do
44 #+ (including jobs that were added during runtime). Through the use
45 #+ of appropriate lockfiles it can be run on several machines
46 #+ concurrently without duplication of calculations [which run a couple
47 #+ of hours in my case, so I really want to avoid this]. Also, as search
48 #+ always starts again from the beginning, one can encode priorities in
49 #+ the file names. Of course, one could also do this without `continue
