Apply a patch directly from a URL without downloading it first.

dapply

#!/bin/bash

# Downloads and applies a patch from Drupal.org.
if [ -z "$1" ] 
then
  echo "You need to supply a URL to a patch file."
  exit
fi

URL=$1;

# Download a patch and apply it.
curl $URL | git apply -v --index
# Commit patch and add a log message.
git commit -m "Applied $URL."

In the commit line, you could use parameter expansion to cleanup the URL and to display just the patch file name.

git commit -m "Applied ${URL##*/}."

The result would be "Applied <file.patch>" as opposed to a potentially long ugly commit message.
