Linux shell命令按块读取/打印文件块 [英] Linux shell command to read/print file chunk by chunk

问题描述

有一个标准的Linux命令，我可以用块来读取文件块？
例如，我有一个大小为6kB的文件。我想读/打印第一个1kB，然后第二个1kB ...
似乎猫/头/尾不会工作在这种情况下。

谢谢非常多。

解决方案

dd会这样做
$ b $ $ pre> dd if = your_file of = output_tmp_file bs = 1024 count = 1 skip = 0


然后对第二个块跳过= 1，依此类推。

然后你只需要读取output_tmp_file就可以得到块。

Is there a standard Linux command i can use to read a file chunk by chunk? For example, i have a file whose size is 6kB. I want to read/print the first 1kB, and then the 2nd 1kB ... Seems cat/head/tail wont work in this case.

Thanks very much.

解决方案

dd will do it

dd if=your_file of=output_tmp_file bs=1024 count=1 skip=0

And then skip=1 for the second chunk, and so on.

You then just need to read the output_tmp_file to get the chunk.
