grep is a versatile command with many variations (grep, egrep, fgrep, then various implementations). It uses a regula expression (regex) pattern to filter input. But then there are basic and extended flavors of regex - leading to even more confusion. And, beware that there are lots of bad examples of regex in the wild... There are two critical questions to ask when you use grep: which grep implementation are you using? what is the flavor of the regex? Here are some examples for gnu grep v2.7:

The following code (573 characters) doesn't work as a bookmarklet. However, <a href="alert('Hi');">Short Bookmarklet</a> works. Actually, you don't have to save the link as a bookmark in order to test, just click the link, nothing happens if the length limit is exceeded.
<a href='javascript:alert("var c = document.create... If the bookmarklet code is too long, you can save the JavaScript code on a server and use this function to bring it back to the page:...

You can use the ntfsresize utility on Linux to shrink or expand an NTFS partition (boot, for example, with the DRBL live cd).
To shrink an NTFS partition:
shrink NTFS (the file system) with ntfsresize.
re-create a smaller partition to hold the shrinked file system with FDisk.
To expand an NTFS partition:
Recreate a partition that's bigger than the previous one.
expand NTFS to the full size of the new partition.
The following are from excerpts from ntfsresize FAQ (Frequently Asked Questions) :
