如何使脚本生成文件，从百分比分配插入文本？ [英] How to make a script to generate files and insert text from a percentage distribution?

问题描述

我在bash / perl的脚本真正的新手，但必须拿出一个解决这个问题，我有。

I'm a true novice with bash/perl scripting but have to come up with a solution to this problem I have.

我需要生成从 1-9 ， A到Z 和<$英文字母命名的文件C $ C> A到Z 。
所以总共会有61的文件。

I need to generate files named after the english alphabet from 1 to 9, a to z and A to Z. So in total there will be 61 files.

之后，我需要根据pre-定义分布插入文本到每一个文件，说：

After that I need to insert text to each file according to a pre-defined distribution, say:

text1 80%
text2 10%
text3 5%
text4 2%
text5 2%
text6 1%

当每个文件只包含一个文本，并从这个例子是有80％的机会，该文件名为 C 例如包含文本文本1 。同样，名为 7 将有5％的几率包含文本文字3 。

When each file contains only one text and from the example there is a 80% chance that the file named C for instance will contain the text text1. Similarly, The file named 7 will have 5% chance to contain the text text3.

我的问题是从哪里开始？什么是preferred的bash或Perl？我想生成的文件会有些容易，但呼应的文字根据分配的文件将是棘手的。

My question is where to start? what is preferred bash or perl? I think generating the files would be somewhat easy but echoing text to files according to a distribution will be tricky.

这是我在哪里使用bash：

This is where I'm at using bash:

创建一个文件，然后输入相同的文字：

Create files and enter same text:

for f in {a..z} {A..Z} {1..9}
do
    echo text > "$f"
done

编辑：这是ubuntu下10.4

It's under ubuntu 10.4

推荐答案

创建文件是在bash小事，填充它们不是那么干净，但不是所有的坏：

Creating the files is trivial in bash, filling them isn't quite so clean but isn't all that bad:

for file in {1..9} {a..z} {A..Z}; do 
    (
    line=$((RANDOM % 100))
    if (( line < 80 )); then 
        echo text1
    elif (( line < 90 )); then 
        echo text2
    elif (( line < 95 )); then 
        echo text3
    [...]
    fi
    ) >$file
done

$ RANDOM 不是随机性的重要来源，但它可能是罚款这一点。

$RANDOM isn't a great source of randomness, but it's probably fine for this.
