[shell] bash数组（for时排序）

for处理时会自动把顺序按A-Z排序了

[root@XM-v106 ~]# bash b.sh
A ->
B ->
C ->
D ->
E ->
[root@XM-v106 ~]# cat b.sh
#!/bin/bash
declare -A array
array=([B]= [A]= [E]= [D]= [C]= )
for i in ${!array[*]}
do
    echo "$i -> ${array[$i]}"
done

解决数组排序

[root@XM-v106 ~]# bash a.sh
B
    field1:
    field2:
    field2:
A
    field1:
    field2:
    field2:
C
    field1:
    field2:
    field2:
[root@XM-v106 ~]# cat a.sh
#!/bin/bash
declare -a array=(B A C)
declare -a A=(  )
declare -a B=(  )
declare -a C=(  )
for i in ${array[@]}
do
    field1=$(eval echo \${$i[]})
    field2=$(eval echo \${$i[]})
    field3=$(eval echo \${$i[]})
    echo $i
    echo "    "field1:$field1
    echo "    "field2:$field2
    echo "    "field2:$field3
done
