Recently when I tried to upgrade my Linux system, I encountered system libraries dependency issue, as a result wget, curl, scp and telnet are all not usable. How could I upload the library files to the system to fix the issue?
Luckily Python works well. I can easy download a file in command-line and save it into right place. Here it is,
# python Python 2.4.3 (#1, Oct 23 2012, 22:02:41) [GCC 4.1.2 20080704 (Red Hat 4.1.2-54)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import urllib >>> urllib.urlretrieve("http://www.admon.org/tmp/libaudit.so.0.0.0", "/lib64/libaudit.so.0.0.0") ('/lib64/libaudit.so.0.0.0', <httplib.HTTPMessage instance at 0x2ad6e9641560>) >>> quit() 'Use Ctrl-D (i.e. EOF) to exit.'
There are two more ways for downloading files with Python,
Example: Downloading with urllib2
import urllib2 f = urllib2.urlopen(url) data = f.read() with open("/path/to/file.zip", "wb") as code: code.write(data)
Example: Downloading with requests
import requests r = requests.get(url) with open("/path/to/file.zip", "wb") as code: code.write(r.content)
