I'm utterly confused by this one-liner from here , that pretty prints the %PATH% variable. ECHO.%PATH:;= & ECHO.% Could you break this one-liner up, and explain what each part means? For example, How is %PATH% split on semicolons? The PATH variable is normally referred to as %PATH% . What's the syntax used here? What do ECHO.% and :;= mean? Where is the "for each line, echo it out" logic? I'd also appreciate it if you could point to any resources that explain the syntax.

Could you break this one-liner up, and explain what each part means?

For example,

How is %PATH% split on semicolons?
The PATH variable is normally referred to as %PATH%. What's the syntax used here?
What doECHO.% and :;= mean?
Where is the "for each line, echo it out" logic?

I'd also appreciate it if you could point to any resources that explain the syntax.
