shell 結合數組讀取指定目錄下的相關文件名並存入文件

#!/bin/bash
echo  當前系統爲: hostname
echo  家目錄爲:
echo  $HOME
echo "-----del old file:such as tmp*_list.txt---"
rm tmp*_list.txt
sleep 1
echo "----begin exportName----" 
dirs=($HOME/bin $HOME/dfes_bin $HOME/fes_bin $HOME/lib $HOME/lib/graph)
txts=(tmp_bin_name_list.txt tmp_dfes_bin_name_list.txt tmp_fes_bin_name_list.txt tmp_lib_name_list.txt tmp_lib_graph_name_list.txt)
#獲取數組長度
dirs_num=${#dirs[@]}
for(( i=0;i<${#dirs[@]};i++))
do
fileNum=`ls -l ${dirs[i]} |grep "^-"|wc -l`
echo "統計的目錄爲==${dirs[i]},目錄下的文件個數爲==$fileNum,統計結果保存的文件爲==$HOME/${txts[i]}"
for file in `ls -l ${dirs[i]}`
