Shell数组

案例代码

#!/bin/bash

# 定义数据
array1=()
# 给数组赋值
array1[0]="林黛玉"
array1[1]="薛宝钗"
array1[2]="贾元春"
# 数组
echo "数组下标为0的元素：${arrar1[0]}"
echo "数组最后一个元素：${array1[-1]}"
echo "数组中所有的元素：${array1[@]}"
echo "数组中所有的元素：${array1[*]}"
echo "数组的长度：${#array1[*]}"
echo "数组所有下标：${!array1[*]}"
# 遍历数组
for item in ${array1[@]}
do
  echo "1.数组内容：${item}"
done
# 修改数组下标为0的元素
echo "修改数组下标为0的元素"
array1[0]="贾宝玉"
# 遍历数组
for ((i=0;i<${#array1[*]};i++))
do
  echo "2.数组内容："${array1[$i]}
done
# 删除数组下标为1的元素
echo "删除数组下标为1的元素"
unset array1[1]
# 遍历数组
for item in ${array1[*]}
do
  echo "3.数组内容：${item}"
done
# 数组中的下标为：0 2
echo "数组所有下标：${!array1[*]}"

# 定义数组
array2=(张天师 洪太尉 高俅 王进)
for item in ${array2[*]}
do
  echo "====>$item"
done

# 逗号分割为数组
str="史进,朱武,陈达,杨春"
echo "str=${str//,/ }"
array3=(${str//,/ })
for item in ${array3[@]}
do
  echo "$item"
done

Shell的declare关联数组

案例代码

#!/bin/bash

# declare关联数组
declare -A array1
array1["one"]="三国演义"
array1["two"]="水浒传"
array1["three"]="西游记"
array1["four"]="红楼梦"
echo "key为one的值：${array1[one]}"
echo "key为two的值：${array1[two]}"
echo "key为three的值：${array1[three]}"
echo "数组的所有下标：${!array1[*]}"
echo "数组的长度：${#array1[*]}"
echo "数组的内容：${array1[*]}"
echo "数组的内容：${array1[@]}"
echo "删除下标为four的元素"
unset array1["four"]

# declare关联数组
declare -A array2
array2=(["one"]="三国演义" ["two"]="水浒传" ["three"]="西游记" ["four"]="红楼梦")
echo "数组的所有下标：${!array2[*]}"
echo "数组的长度：${#array2[*]}"
echo "数组的内容：${array2[*]}"
echo "数组的内容：${array2[@]}"
echo "key为one的值：${array2[one]}"
echo "key为two的值：${array2[two]}"
echo "key为three的值：${array2[three]}"
echo "key为four的值：${array2[four]}"

# 关联数组的遍历
keys=${!array2[*]}
for key in ${keys[@]}
do
  echo "----key=$key,value=${array2[$key]}"
done

Shell二维数组

案例代码

#!/bin/bash

series=(xiyou shuihu)
xiyou=("唐僧" "孙悟空" "猪八戒" "沙僧")
shuihu=("宋江" "卢俊义" "吴用" "公孙胜")

# 遍历
for item in ${series[@]}
do
  echo "----${item}"
  array=$item[@]
  arrayContent=(${!array})
  for e in ${arrayContent[@]}
  do
    echo "--------${e}"
  done
done

echo "------------------------------------------------"

# 遍历
for item in ${series[@]}
do
  echo "----${item}"
  array=$item[@]
  arrayContent=(${!array})
  arrayLength=${#arrayContent[@]}
  echo "----长度为：$arrayLength"
  for (( i=0;i<$arrayLength;i++))
  do
    echo "--------${arrayContent[$i]}"
  done
done
