This command looks for a single file named emails.txt which is located somewhere in my home directory and cd to that directory. This command is especially helpful when the file is burried deep in the directory structure. I tested it against the bash shells in Xubuntu 8.10 and Mac OS X Leopard 10.5.6

Not that it's a deal breaker, but this command messes up if there is multiple files with the same name in separate directories:
dirname: extra operand `/home/user/docs/emails.txt'
Adding "|head -1" after 'emails.txt' helps but you don't necessarily know which directory you're going to end up in.
cd $(dirname $(find ~ -name emails.txt|head -1))you could scope out the directory list before cd'ing with something like this:
find ~ -name emails.txt -exec dirname {} \; | sort | uniqthe trailing sort|uniq combo just ensures any directory name returned is only displayed once.
@bwoodacre: nice.
The find will quit after the first file it finds, rather than piping to head -1.
cd $(find ~ -name emails.txt -exec dirname {} \; -quit)
