在有些Linux上自帶了tree命令來一樹狀結構顯示一個目錄，但是在有些linux上沒有自帶這個程式，所以這裡用python寫了一個小程式來實現這個功能，程式碼如下：

[python] view plain copy print?

1. #!/usr/bin/python
2. import os, sys, string  
3. class XXTree:  
4.     def __init__(self):  
5.         pass
6.     def printHelp(self, cmd):  
7.         print'Please use the following cmd:'
8.         print'    ' + cmd + 
   ' dir'
9.         print'e.g.'
10.         print'    ' + cmd + ' /home/fkong/tmp'
11.     def getTree(self, dir):  
12.         list = self.getList(dir, 0)  
13.         treelist = []  
14.         for i in range(0, len(list)):  
15.             fullpath = list[i]  
16.             parpath = os.path.dirname(list[i])  
17.             filename = os.path.basename(list[i])  
18.             if(fullpath == dir):   
19.                 treelist.append(fullpath)  
20.                 continue
21.             path = fullpath.replace(dir, "")  
22.             names = path.split("/")  
23.             name = "`---" + names[len(names) - 1]  
24.             for j in range(1, len(names) - 1):  
25.                 name = "    "
     + name  
26.             treelist.append(name)  
27.             pos = name.index("`")  
28.             j = i - 1
29.             while j > 0:  
30.                 name = treelist[j]  
31.                 if(name[pos] == '`'or name[pos] == ' '):  
32.                     name = name[0: pos] + "|" + name[pos + 1: len(name)]  
33.                     treelist[j] = name  
34.                 else:  
35.                     break
36.                 j = j - 1
37.         for i in range(0, len(treelist)):  
38.             print treelist[i]  
39.     def getList(self, dir, layer):  
40.         list = []  
41.         if layer == 0: list.append(dir)  
42.         files = os.listdir(dir)  
43.         for file in files:  
44.             file = os.path.join(dir, file)  
45.             if os.path.isdir(file):  
46.                 list.append(file)  
47.                 list += self.getList(file, layer + 1)  
48.             else :  
49.                 list.append(file)  
50.         return list  
51. if len(sys.argv) != 2:  
52.     t = XXTree()  
53.     t.printHelp(sys.argv[0])  
54. else:  
55.     t = XXTree()  
56.     dir = sys.argv[1]  
57.     t.getTree(dir)  

#!/usr/bin/pythonimport os, sys, stringclass XXTree: def __init__(self):  pass  def printHelp(self, cmd):  print 'Please use the following cmd:'  print '    ' + cmd + ' dir'  print 'e.g.'  print '    ' + cmd + ' /home/fkong/tmp' def getTree(self, dir):  list = self.getList(dir, 0)  treelist = []    for i in range(0, len(list)):   fullpath = list[i]   parpath = os.path.dirname(list[i])   filename = os.path.basename(list[i])   if(fullpath == dir):     treelist.append(fullpath)    continue       path = fullpath.replace(dir, "")   names = path.split("/")   name = "`---" + names[len(names) - 1]   for j in range(1, len(names) - 1):    name = "    " + name   treelist.append(name)      pos = name.index("`")   j = i - 1   while j > 0:    name = treelist[j]    if(name[pos] == '`' or name[pos] == ' '):     name = name[0: pos] + "|" + name[pos + 1: len(name)]     treelist[j] = name    else:     break    j = j - 1    for i in range(0, len(treelist)):   print treelist[i]   def getList(self, dir, layer):  list = []  if layer == 0: list.append(dir)  files = os.listdir(dir)  for file in files:   file = os.path.join(dir, file)   if os.path.isdir(file):    list.append(file)    list += self.getList(file, layer + 1)   else :    list.append(file)  return listif len(sys.argv) != 2: t = XXTree() t.printHelp(sys.argv[0])else: t = XXTree() dir = sys.argv[1] t.getTree(dir) 

執行效果如下：
