Module pd.find present simple way use filesystem to search and read files on it. File system using showed as simple as using ordinal dict:
>>> import pd.find
>>> f=pd.find.file.File("/etc/sysconfig")
>>> f
'/etc/sysconfig' >>> f.keys() ['harddisk', 'lm_sensors', 'ipw3945d~', 'syscheckerrc', 'mouse'] >>> f['lm_sensors'] '/etc/sysconfig/lm_sensors' >>> print str(f['lm_sensors']) # /etc/sysconfig/lm_sensors - Defines modules loaded by
Other important pakage mission is find files by the way similar to command line find utility:
>>> import pd.find
>>> pd.find.find("/etc/sysconfig",lambda x : x.isreg() and x.check_regex(".*rc"))
<generator object at 0xb7cca7cc> >>> for item in pd.find.find("/etc/sysconfig",lambda x : x.isreg() and x.check_regex(".*rc$")) : ... print item.path ... /etc/sysconfig/xinitrc /etc/sysconfig/syscheckerrc >>>

dereference On true value of this argument searhing will be followed by symbolic link.
Utility return generator of list object find by them.
Tests provided by File Object
mtime Return modification time
atime Return last access time
ctime Return creation time """ return self.__checktime_(stat.ST_CTIME)
newer Return true if object is more newer then input path
check_name Return true if object name are equal to input name
check_path Return true if object path are equal to input path
check_path_regex Return true if regexp matched object path
check_regex Return true if regexp matched object name
check_iregex Return true if regexp matched object name
depth Return current depth on file tree
dele Delete file by path of current object
