在網(wǎng)上看了一篇 Linux tree命令的Python實現(xiàn)，剛好也這個需求，遂下來自己改了一改，滿足自己的需求，先把源碼分享給大家：
- #!/usr/bin/python
- import os, sys, string
- class 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, op):
- list = self.getList(dir, 0, op)
- 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, op):
- 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, op)
- elif op == '-d':
- pass
- else:
- list.append(file)
- return list
-
- if len(sys.argv) < 2 :
- t = XXTree()
- t.printHelp(sys.argv[0])
- else:
- t = XXTree()
-
- dir = None
- if len(sys.argv) == 2:
- dir = sys.argv[1]
-
- op = None
- if len(sys.argv) == 3:
- op = sys.argv[1]
- dir = sys.argv[2]
-
- t.getTree(dir, op)
