Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

This permit to convert an UNIX file to DOS file.

Loops over array of a system var, splits its values and puts the values into %A, %B, %C, %D, and so on.
Create array before, like
Be sure to replace %A, %B, etc. with %%A, %%B, etc. when using this from inside of batch files.
This command loops over all indexes of the system variable array ARRAY and puts its content into %A.
