如何随机的列表，并通过随机列表迭代（庆典） [英] How to randomize a list and iterate through the randomized list (bash)

问题描述

我已经写了一个小bash脚本读取命令（每行一个），在一个文本文件中。
此刻，脚本（如下所示）中，以连续的顺序（在该文件中输入的相同顺序，即）执行的命令。

I have written a little bash script that reads commands (one per line), in a text file. At the moment, the script (shown below), is executing the commands in a sequential order (i.e. in the same order entered in the file).

我想帮助修改下面的脚本，所以它读取命令到一个数组，然后遍历虽然随机列表之前随机化数组（即清单）。

I would like help to modify the script below, so that it reads the commands into an array, then randomizes that array (i.e. list) before iterating though the randomized list.

这是我迄今为止：

while read -r -a array
do
   python make_move.py "${array[@]}"
done < game_commands.dat

我在Ubuntu LTS 10.0.4

I am running bash 4.1.5 on Ubuntu 10.0.4 LTS

我需要在列表中执行所有的命令，与正在执行一次每个命令。

I need to execute ALL of the commands in the list, with each command being executed ONLY ONCE.

推荐答案

您可以使用的 SHUF 命令。

You can shuffle the lines of a file using the shuf command.

修改：使用您code SHUF 看起来

Edit: Your code using shuf would look

while read -r -a array
do
    python make_move.py "${array[@]}"
done < <(shuf game_commands.dat)
