The bc shell utility that is available on most UNIX/Linux distributions defaults to integer arithmetic (i.e. throws away anything after the comma). To prevent this, you can set the “scale” option in bc. E.g., the following command will return 3.333: echo “scale=3; 10/3″ | bc

To insert the output of a command (e.g. ‘ls’) below the cursor, type: :r !ls or :read !ls

To insert the contents of a file called /tmp/myfile.txt below the cursor, type: :r /tmp/myfile.txt or :read /tmp/myfile.txt

The sad things is this actually happened… Credits: xkcd
