Bash: Scripting - Lists symbolic links in directory

# Strictly speaking, a loop isn't really neccessary here,
#+ since the output of the "find" command is expanded into a single word.
# Howerver, it's easy to understand and illustrative this way.
# Failing to quote $(find $directory -type l)
#+ will choke on filenames with embedded whitespace.
