| The regex patterns in this gist are intended to match any URLs, | |
| including "mailto:[email protected]", "x-whatever://foo", etc. For a | |
| pattern that attempts only to match web URLs (http, https), see: | |
| https://gist.github.com/gruber/8891611 | |
| # Single-line version of pattern: | |
| (?i)\b((?:[a-z][\w-]+:(?:/{1,3}|[a-z0-9%])|www\d{0,3}[.]|[a-z0-9.\-]+[.][a-z]{2,4}/)(?:[^\s()<>]+|\(([^\s()<>]+|(\([^\s()<>]+\)))*\))+(?:\(([^\s()<>]+|(\([^\s()<>]+\)))*\)|[^\s`!()\[\]{};:'".,<>?«»“”‘’])) |

A python script for extracting email addresses from text files.You can pass it multiple files. It prints the email addresses to stdout, one address per line.For ease of use, remove the .py extension and place it in your $PATH (e.g. /usr/local/bin/) to run it like a built-in command.
