-e print the file count in the directory tree of directory-path
-t print the file count of different file type in the directory tree
of directory-path.the file type should include "text","ELE","script" and
"other"
-s print the all file names which file size is greater than 1M in the
directory tree of directory-path
-m Create or overwrite the file /tmp/haha that contains all file listing(
with absolute path) of *.mp3 and *.MP3 in the directory-path.
-o Sort all files in directory-path excluding dub-directory by date,
and print the sorted result on STD OUT.printed information should
only include file name,size and date.

test应该是SHELL脚本中的一个命令！用来检查表达式的真假！

[linuxnewer]

瞪着眼睛看。

-h print out help message.
打印帮助信息

-e print the file count in the directory tree of directory-path
打印指定目录路径的目录树下文件的个数
-t print the file count of different file type in the directory tree of directory-path.the file type should include "text","ELE","script" and "other"
打印指定目录路径的目录树下不相同文件的个数。文件类型必须包括
"text","ELE","script" 和 "other" 。

-s print the all file names which file size is greater than 1M in the directory tree of directory-path
打印指定目录路径的目录树下所有大于1m的文件的文件名。

-m Create or overwrite the file /tmp/haha that contains all file listing(with absolute path) of *.mp3 and *.MP3 in the directory-path.

我问的是怎么实现以上的功能啊！不是翻译啊！谢谢

[duke136]

做个字符串分析，然后跳转到相应的shell命令调用shell。

呵呵，我也不懂，随便说说。

[hackerning]

wizardxd() ,我想问的是怎么写SHELL脚本来实现以上的功能啊！

[minimini319]

vi test

然后在里面写

case $1

-h)........

-p)........



主要是注意参数1是$1,参数2是$2,然后再用case....esac在每个选项里写入具体的如create语句就可以了阿

[wizardxd]

在shell中我不知道如何实现。
用c倒是写过类似的程序~
不知道是否有用~

[hackerning]

你这只是把程序的构架说了一遍，这个我也知道啊，就是想问你具体的那些功能用哪些命令或方法可以实现啊！谢谢 minimini319(minimini）！

[qisiwole]

PYTHON 很好用！

[linuxnewer]

1.you can choose your preferred shell(bash,sh,csh..)
什么意思？

[minimini319]

-h 这个。。。你应该知道吧？

-e ls -a $2 |wc -w

-t ls -a $2 |grep 'file type'|wc -w

-s ls -al $2 |awk '$5 > 2048 {print $3}'

下面一题看不懂？/tmp/haha是文件？目录？

[minimini319]

终于看懂了。。。

-m (ls -al $2|grep 'file type')>/tmp/haha

最后一道题dub-directory是什么意思地说？不明白~~~

[hackerning]

dub-directory是子目录的意思

[minimini319]

子目录：sub-directory??

-o ls -rtal $2 |awk '{print $3 $5 $7}'

[HOOLOO]

I don't know!

[minimini319]

这贴可以结了吗？

[hackerning]

可以！
