First, traversing all files under the folder, output file name
Copy Code code as follows:
def traverse_dir (File_path)
If File.directory? File_path
Dir.foreach (file_path) do |file|
If file!= "." and File!= "..."
Traverse_dir (file_path+ "/" +file)
End
End
Else
Puts "File:#{file.basename (File_path)}, Size:#{file.size (File_path)}"
End
End
Traverse_dir (' D:/apache-tomcat ')
Second, Ruby Traverse folder
Copy Code code as follows:
def get_file_list (Path)
Dir.entries (path). Each do |sub|
If sub!= '. ' && sub!= ' ... '
If File.directory? ("#{path}/#{sub}")
Puts "[#{sub}]"
Get_file_list ("#{path}/#{sub}")
Else
Puts "|--#{sub}"
End
End
End
End
Three, Python how to traverse a directory output all file names
Copy Code code as follows:

Import OS
Def getfilelist (dir, filelist):
Newdir = Dir
If Os.path.isfile (dir):
Filelist.append (Dir.decode (' GBK '))
Elif Os.path.isdir (dir):
For S in Os.listdir (dir):
#如果需要忽略某些文件夹, use the following code
#if s = = "xxx":
#continue
Newdir=os.path.join (Dir,s)
Getfilelist (Newdir, FileList)
return filelist
List = getfilelist (' D:\\workspace\\pydemo\\fas ', [])
For E in list:
Print E
Result
Copy Code code as follows:
D:\workspace\PyDemo\fas\file1\20141113\a.20141113-1100.log
D:\workspace\PyDemo\fas\file1\20141113\a.20141113-1101.log
D:\workspace\PyDemo\fas\file1\20141113\a.20141113-1140.log
D:\workspace\PyDemo\fas\file2\20141113\a.20141113-1100.log
D:\workspace\PyDemo\fas\file2\20141113\a.20141113-1101.log
D:\workspace\PyDemo\fas\file2\20141113\a.20141113-1140.log
Four, concise traversal of the wording
Copy Code code as follows:
Import OS
def iterbrowse (path):
For home, dirs, the files in Os.walk (path):
For filename in Files:
Yield Os.path.join (home, filename)
For FullName in Iterbrowse ("/home/bruce"):
Print FullName
