I'm looking for a way to search for all the symbolic links on a NTFS filesystem on Windows Vista or 7.
It would be even better if I could specify a specific target to see if it has any symlinks pointing to it, but a way to search for them all would be great, too.
Here's the best way I've found thus far:
dir /a:l /s
But it's ugly. I'd prefer a listing that showed one file per line in the format of target => source or something similar. Grepping for SYMLINK doesn't do well because of the multi-line format. The /B bare switch doesn't give anything but the target filename, too.
Note that grep is a multiline tool. You can use -an to grab both the preceding and next n lines, and -An to just grab the next n lines. For example, grep -A10 configure would grab the next ten lines after finding the word "configure". If you had 2 instances of the word configure 3 lines apart, then you'd end up grabbing 14 lines total.
Since Everything search has been re-written (January 2013), you can now search for attributes. A query of "attrib:L" will reveal all Symbolic Links of various types on your computer. Show Attributes column (Ctrl+Shift+8) to sort by attribute.
You can also create a Filter for that particular attribute search (Search, Add to Filters) if you do that type of search often or want to assign a keyboard shortcut.
I did notice the initial attrib: search appeared to lock-up Everything temporarily, but finished after a few seconds... worth the small wait for such a powerful tool.
Try SageLinks - a small freeware open-source utility for Windows, it can find and re-check all symlinks as well as junctions and shortcuts:
You can try the free tool, Junction by SysInternals
To search all the symlinks on a drive, go to the root and type:
C:\> junction -s -q
-s goes through all the subdirectories
-q ignores errors such as "Access is denied."
That will give you all the reparse points that Windows is currently using.
If you want to determine if a specific file or folder is a reparse point, just type the utility name and file/folder name after. Be careful with folder names since adding a backslash may change results.

For all file searches on Windows systems i suggest using Everything. It's ultra fast and very lightweight.
I too was looking for this capability and haven't seen it elsewhere. I've added it to my Windows libraries for Python. Unfortunately, if you aren't already an avid Python programmer, you have a few steps to get everything installed.

\Python26\scripts\easy_install jaraco.windows
After following these steps, you should have a script called \python26\scripts\find-symlinks.exe or \python26\scripts\find-symlinks-script.py which you can execute with an optional pathname to search out symlinks. It will search out the symlinks and report the results, one line each. I tested this procedure on a clean install of Windows 7.

> \python26\scripts\find-symlinks
D .\mylink --> \windows
.\myfilelink --> \windows\notepad.exe
Cygwin/bash script for win7
c:\> cat find-dead-links.sh

find . -maxdepth 3 -type l -print0 |
while IFS= read -r -d $'\0' file ;do
[[ -e "$file" ]] && continue
echo "Bad link $file"
done
