我试图将cat输出存储到变量中,然后尝试回显它.然后我想杀死这个过程.

#!/bin/bash

var = $(cat tmp/pids/unicorn.pid)

echo $var
sudo kill -QUIT $var

如果有人能告诉我哪里出错了,请

如何在一行中列出多个赋值.

>>>a,b,c = [1,2,3]
>>> a
1
>>>b
2
>>>c
3

但是我应该怎么做才能分配其余的子数组 c

>>> a,b,c = [1,2,3,4,5,6,7,8,9] ##this gives an error but how to ..?
>>> a
1
>>>b
2
>>>c
[3,4,5,6,7,8,9]

这该怎么做？

我想拆分哈希数组.

.split 没有努力.

我想将它一分为二,同时保持顺序,这样可能是 .partion,.select,group_by不会为我工作.

这件事

allay = [
  {name: "Iron Man", power: "Tech"},
  {name: "Spiderman", power: "Iron Man as Uncle"},
  {name: "Thor", power: "God"},
  {name: "Hawk Eye", power: "None"},
  {name: "Black Widow", power: "love her"}
]

以此为输出

=> [
  [
    {name: "Iron Man", power: "Tech"},
    {name: "Spiderman", power: "Iron Man as an Uncle"},
    {name: "Thor", power: "God"}
  ],
  [
    {name: "Hawk Eye", power: "None"},
    {name: "Black Widow", power: "love her <3"}
  ]
]
