shell 字符串转数组

test.sh脚本如下：

apps="${1}"  
#按“T”分隔  
arr=(${apps//T/ })  
for app in ${arr[@]}  
do   
  apps2="${app}"  
  #按“,”分隔  
  arr2=(${apps2//,/ })  
  for app2 in ${arr2[@]}  
  do  
     echo "${app2}"  
  done  
done  

调用并输出：

sh test.sh 1,2T11,12T111,112  
  
1  
2  
11  
12  
111  
112
