shell：delete_executable_file - 删除当前文件夹的可执行文件（linux）

一、 delete_executable_file - 删除当前文件夹的可执行文件（linux）

 1 #!/usr/bin/bash
 2 
 3 
 4 # file_name = delete_executable_file
 5 # delete executable files in current directory. but it dose not delete itself.
 6 
 7 
 8 keep_file="delete_executable_file"
 9 count=0
10 
11 
12 for exe_file in $(ls)
13 do
14         if [ $exe_file != $keep_file ]
15         then
16                 if [ -x $exe_file ]
17                 then
18                         echo "DELETE_FILE_$count = " $exe_file
19                         rm -rf $exe_file
20                         count=$(($count+1))
21                 fi
22         fi
23 
24 done
