Saving a file with the date and time using shell

Question

I have something in Python which saves a file in the following datetime format:

>>> s = time.strftime('%Y%m%d%H%M%S')
>>> print s
20121208145544

Things have changed slightly and this now needs to be done in shell. Is there a way to get the datetime in exactly the same format using shell?

Answer 1

Something like

touch filename_`/bin/date +%Y%m%d%H%M%S`.txt

creates an empty file

filename_20130104112845.txt

Answer 2

使用date命令 ，它采用完全相同的格式参数，并带有+ ：

date +%Y%m%d%H%M%S

Answer 3

This works too:

>>> z = time.strftime('%Y%m%d%H%M%S')
>>> file_ = open(z+'.txt', 'w')
>>> file_.close()

This creates 20130104160557.txt.
