So you've followed this "tutorial": http://www.n1tr0g3n.com/?p=1123
During that it told you to:
printf “PATH=$%sPATH:%s/bin/feedingbottle/\n” | tee -a ~/.bashrc
If you look closely you'll see that it's using curly quotes instead of the straight double-quotes (eg "). To Bash curly quotes are just another character, they aren't special like straight quotes.
So what you've actually done is added this whole corrupted line into ~/.bashrc. You need to fix it. Open ~/.bashrc in Gedit, or whatever you like, find this line (it's almost certainly at the bottom) and replace it with:
PATH=$PATH:/bin/feedingbottle/
And be more careful in the future.
