如何连接具有相同preFIX（很多prefixes）文件？ [英] How to concatenate files with the same prefix (and many prefixes)?

问题描述

我有相同preFIX许多文件，只下划线后的位是不同的。而且我有很多prefixes的！
下划线没有其他地方出现在文件名。我怎么可以连接都具有相同的preFIX的文件到一个新的？
我补充说，我有成千上万不同的prefixes的，我不能养活他们的循环。

I have many files that have the same prefix, only the bit after the underscore is different. And I have many prefixes as well! Underscore does not appear anywhere else in the file name. How can I concatenate all the files with the same prefix into a new one? I am adding that I have thousands of different prefixes and I cannot feed them to the loop.

推荐答案

您可以这样做：

cat /path/prefix* >> new_file

它将猫（即串联文件和打印到标准输出）的名字匹配的所有文件 /路径/ preFIX 。文本的其余部分是可以是不同的。

It will cat (that is, concatenate files and print on the standard output) all files whose name matches /path/prefix. The rest of the text is what can be different.

执行，这是好做之前 LS /路径/ preFIX * ，以确保它得到所有（且仅这些）文件要考虑到考虑。

Before executing that it is good to do ls /path/prefix* to make sure it gets all (and only these) files you want to take into consideration.

$ ls
aa_bb  prefix_23  prefix_235  prefix_nnn
$ ls prefix_*
prefix_23  prefix_235  prefix_nnn
