.. py:function:: pydu.file.makedirs(path, mode=0o755, ignore_errors=False, exist_ok=False)
|
|
|
|
Based on ``os.makedirs``,create a leaf directory and all intermediate ones.
|
|
``mode`` default is ``0o755``. When make an exists path, if exist_ok is false,
|
|
``makedirs`` will raise an ``Exception``. If ``ignore_errors`` which will ignore
|
|
all errors raised by ``os.makedirs``.
|
|
|
|
>>> from pydu.file import makedirs
|
|
>>> makedirs('test1/test2')
|
|
>>> makedirs('test1',exist_ok=True)
|
|
>>> makedirs('test1')
|
|
Traceback (most recent call last):
|
|
... OSError: Create dir: test1 error.
|
|
|
|
.. py:function:: pydu.file.remove(path, mode=0o755, ignore_errors=False, onerror)
|
|
|
|
Remove a file or directory.
|
|
|
|
If ``ignore_errors`` is set, errors are ignored; otherwise, if `onerror`
|
|
is set, it is called to handle the error with arguments (`func` ,
|
|
`path` , `exc_info` ) where func is platform and implementation dependent;
|
|
`path` is the argument to that function that caused it to fail; and
|
|
`exc_info` is a tuple returned by `sys.exc_info()`. If `ignore_errors`
|
|
is `False` and `onerror` is None, an exception is raised.

.. py:function:: pydu.file.removes(paths, mode=0o755, ignore_errors=False, onerror)
|
|
|
|
Remove a list of file and/or directory.Other parameters same as `remove`.
|
|
|
|
>>> from pydu.file import makedirs
|
|
>>> from pydu.file import remove
|
|

|

|
.. py:function:: pydu.file.open_file(path, mode='wb+', buffer_size=-1, ignore_errors=False):
|
|
|
|
Open a file, defualt mode ``wb+``. If path not exists, it will be created
|
|
automatically. If ``ignore_errors`` is set, errors are ignored.
|
|
|
|
>>> from pydu.file import open_file
|
|
>>> open_file('test.txt')
|
|
>>> ls
|
|
test.txt
|
|
>>> open_file('test1.txt',mode='r')
|
|
Traceback (most recent call last):

... OSError: Open file: test1.txt error
|
|
|
|
.. py:function:: pydu.file.copy(src, dst, ignore_errors=False, follow_symlinks=True):
|
|
|
|
Copy data and mode bits (`cp src dst`).Both the source and destination
|
|
may be a directory.When `copy` a directory,which contains a symlink,if
|
|
the optional symlinks flag is true, symbolic links in the source tree
|
|
result in symbolic links in the destination tree; if it is false, the
|
|
contents of the files pointed to by symbolic links are copied.When copy
|
|
a file,if follow_symlinks is false and src is a symbolic link, a new
|
|
symlink will be created instead of copying the file it points to,else
|
|
the contents of the file pointed to by symbolic links is copied.
|
|
|
|
>>> from pydu.file import copy,symlink
|
|
>>> from pydu.file import makedirs,open_fle
|
|
>>> open_fle('test/test.txt')
|
|
>>> symlink('test/test.txt','test/test.link')
|
|
>>> copy('test/test.link','test/test_copy1.link')
|
|
>>> copy('test/test.link','test/test_copy2.link',follow_symlink=False)
|
|
|
|
.. py:function:: pydu.file.touch(path):
|
|
|
|
Open a file as write,and then close it.
|
|
|
|
>>> from pydu.file import touch
|
|
>>> touch('test.txt')
|
|
|
|
.. py:function:: pydu.file.symlink(src, dst, overwrite=False, ignore_errors=False)
|
|
|
|
``symlink`` only work on `Unix-like` system, it create a symbolic link pointing
|
|
to source named link_name.If dist is exist and overwrite is true,a new
|
|
symlink will be created.
|
|
|
|
>>> from pydu.file import symlink
|
|
>>> symlink('test.txt','test.link')
|
|
|
|
.. note:: ``symlink`` can only be used on ``unix-like`` system.
|
|
|
|
.. py:function:: pydu.file.link(src, dst, overwrite=False, ignore_errors=False):
|
|
|
|
``link`` only work on `Unix-like` system, it create a hard link pointing to
|
|
source named link_name.If dist is exist and overwrite is true,a
|
|
new link will be created.
|
|
|
|
>>> from pydu.file import link
|
|
>>> link('test.txt','test.link')
|
|
