shell 字符串轉數組

 

#!/bin/bash
string="hello,shell,split,test" 
#將,替換為空格 
array=(${string//,/ })  
 
for var in ${array[@]}
do
   echo $var
done 

輸出

bogon:conf macname$ ./test.sh 
hello
shell
split
test

 

還可以寫成

#!/bin/bash
string="hello,shell,split,test"  
array=(`echo $string | tr ',' ' '` )  
 
for var in ${array[@]}
do
   echo $var
done 
 

或者

#!/bin/bash
string="hello,shell,split,test"  
 
#對IFS變量 進行替換處理
OLD_IFS="$IFS"
IFS=","
array=($string)
IFS="$OLD_IFS"
 
for var in ${array[@]}
do
   echo $var
done
