Edit: This does not seem to work anymore.
This is a stripped-down snippet from sonata to fetch music album covers from the amazon website.

There is a minimal web server in the python standard library. To use it, change to the directory you want to serve and execute the script below:
#!/usr/bin/env python import SimpleHTTPServer, BaseHTTPServer try: BaseHTTPServer.test(SimpleHTTPServer.SimpleHTTPRequestHandler, BaseHTTPServer.HTTPServer) except KeyboardInterrupt: print '^C received, bye bye!'
By default, the directory is served on port 8000, so point your browser to http://localhost:8000/ to see your freshly online website. Alternatively, you can specify the port as first argument. For example:
> simplewebserver.py 1234
An example of using regular expressions in python to extract the email addresses from a text file.
#!/usr/bin/env python """ Description: extract email addresses from stdin to stdout Usage example: cat whatever.txt | extract-email.py | sort -fu > addr.txt """ import re, sys email_pattern = re.compile('([\w\-\.]+@(\w[\w\-]+\.)+[\w\-]+)') for line in sys.stdin: # there are several matches per line for match in email_pattern.findall(line): print match
This is my totally not original backup script. I have symbolic links sitting in a directory, to files and folders I want to save. This directory is saved on a remote host.
#!/bin/bash set -u set -e # The directory to be backed up DIR="$HOME/backed.up/" # The remote host RHOST="whatever" # The directory on the remote host RDIR=`hostname`/ # rsync options reminder: # -a archive mode # -v verbose # -z compression during transfer # --delete remove files that were deleted in the source directory # --copy-unsafe-links # when a symlink is encountered, the referent is copied # instead, *only* if it is out of the saved tree rsync -avz --delete --copy-unsafe-links -e ssh $DIR $RHOST:$RDIR
