unix（在bash shell中）的shell脚本，用于将文件从一个位置（即目录）复制到另一个位置，而不使用cp命令

Can anyone help me with a shell script in unix(in bash shell) for copying a file from one location(i.e a directory), to other, without using cp command at all(not using it in the script also.Any other command /utility can be used in the script).Can it be really done ? I could'nt find a way out.Any help would be appreciated...

任何人都可以帮助我在unix(在bash shell中)使用shell脚本将文件从一个位置(即目录)复制到其他位置,而不使用cp命令(也不在脚本中使用它。任何其他命令/实用程序可以在脚本中使用)。真的可以吗?我无法找到出路。任何帮助都会受到赞赏......

How many options do you want?

你想要几个选项?

• rcp
• scp
• dd
• perl
• python
• cat
• while / read / echo

while / read / echo

That is nowhere near exhaustive. You can be creative...have fun!

这远不是详尽无遗的。你可以有创意......玩得开心!

You could use:

你可以使用:

1. cat to create a C source file, copy.c

cat创建一个C源文件copy.c

2. make or cc to compile it

make或cc编译它

3. And then run it to do the copying.

然后运行它来进行复制。

You could use:

你可以使用:

1. cat /usr/bin/cp > x

cat / usr / bin / cp> x

2. chmod +x x

chmod + x x

3. ./x old new

./x旧的新

But that is probably cheating.

但这可能是作弊。

Presumably you can cat and redirect the output. Since this sounds like homework, I'll leave it to you to work out the exact syntax.

大概你可以cat并重定向输出。因为这听起来像家庭作业,我会留给你来弄清楚确切的语法。

Erghm. Why?! Anyway...

Erghm。为什么?!无论如何...

cat file1 > some/other/dir/file2

install is a good one.

安装是一个很好的。
