I'm using Python 2.7.6 on an openSUSE linux system.
I'm trying to convert a shell (bash) script to a python script, and
everything's worked OK except this. The following line in the shell script
btrfs subvolume snapshot /home/bob/A3/documents /home/bob/A3/docsnaps/`date
+%y-%m-%d_%H-%M`
creates a folder of the form
/home/bob/A3/docsnaps/14-07-08_17-32
ie. the name is a formatted date string, which is what I want.
In my python script, this
subprocess.call('btrfs', 'subvolume', 'snapshot', '/home/bob/A3/documents',
'/home/bob/A3/docsnaps/`date +%y-%m-%d_%H-%M`')
creates a folder
/home/bob/A3/docsnaps/`date +%y-%m-%d_%H-%M`
In other words, it does not format the date, but takes the stuff between the
backticks (`) as a string.
I tried adding shell=True, but got the following error:
Traceback (most recent call last):
File "/home/bob/bin/btrfs-backup.py", line 55, in <module>
subprocess.call('btrfs', 'subvolume', 'snapshot', '/home/bob/A3/documents',
'/home/bob/A3/docsnaps/`date +%y-%m-%d_%H-%M`', shell=True)
File "/usr/lib64/python2.7/subprocess.py", line 522, in call

File "/usr/lib64/python2.7/subprocess.py", line 658, in __init__
raise TypeError("bufsize must be an integer")
TypeError: bufsize must be an integer
Any suggestions, please?
