Collection of multiple Ruby Traversal folder code instances

This article mainly introduces the collection of multiple Ruby Traversal folder code instances, this article summed up 4 pieces of code, small series recommend the last method, because it is very simple and elegant, need friends can refer to the

First, traversing all files under the folder, output file name

The code is 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

The code is 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

The code is 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:workspacepydemofas ', [])

For E in list:

Print E

Result

The code is as follows:

D:workspacepydemofasfile120141113a.20141113-1100.log

D:workspacepydemofasfile120141113a.20141113-1101.log

D:workspacepydemofasfile120141113a.20141113-1140.log

D:workspacepydemofasfile220141113a.20141113-1100.log

D:workspacepydemofasfile220141113a.20141113-1101.log

D:workspacepydemofasfile220141113a.20141113-1140.log

Four, concise traversal of the wording

The code is 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
