在shell中，数组变量的赋值有两种方法：
(1) name = (value1 ... valuen)此时下标从0开始
(2) name[index] = value
example:
- #！/bin/sh
- #arrayTest
- name=(yunix yhx yfj)
- echo "array is:${name[@]}"
- echo "array length is:${#name[*]}"
- echo ${name[1]}
- name[1]=yang
- echo ${name[1]}
- read -a name
- echo ${name[1]}
- echo "loop the array"
- len=${#name[*]}
- i=0
- while [ $i -lt $len ]
- do
- echo ${name[$i]}
- let i++
- done
result:
array is:yunix yhx yfj
array length is:3
yhx
yang
a b c d e
b
loop the array
a
b
c
d
e
下面的是关于数组的输出实例
example:
#!/bin/sh
- #arrayLoopOut
- read -a array
- len=${#array[*]}
- echo "array's length is $len"
- echo "use while out the array:"
- i=0
- while [ $i -lt $len ]
- do
- echo -n "${array[$i]}"
- let i++
- done
- echo
- echo "use for out the array:"
- for ((j=0;j<"$len";j=j+1))
- do
- echo -n ${array[$j]}
- done
- echo
- echo "use for in out the array:"
- for value in ${array[*]}
- do
- echo -n $value
- done
result:
a b c d e f g
array's length is 7
use while out the array:
abcdefg
use for out the array:
abcdefg
use for in out the array:
abcdefg
