在有些Linux上自带了tree命令来一树状结构显示一个目录，但是在有些linux上没有自带这个程序，所以这里用python写了一个小程序来实现这个功能，代码如下：
#!/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):
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 list
if len(sys.argv) != 2:
t = XXTree()
t.printHelp(sys.argv[0])
else:
t = XXTree()
dir = sys.argv[1]
t.getTree(dir)
运行效果如下：
$ ./xxtree.py /home/fkong/workspace/jutility/.svn
/home/fkong/workspace/jutility/.svn
