变量定义在for..in循环中给出错误

Question

如何在for..in循环中定义变量

示例：

#!/bin/bash
api ="api keys"
for i in {1..305}; do
  wget "https://api.shodan.io/shodan/host/search?key=$api&query=&facets={facets}&page=$i"
done

但这会导致以下错误：

./script.sh: line 2: api: command not found

Answer 1

Bash变量声明是空间敏感的。因此，请勿在变量声明中加上空格。看看rule SC1068。

# Change:
api ="api keys" 
# To:
api="api keys"
