Is it possible to use a piped stdin stream inside a batch file?

Answer 1

The set "line=!line:*:=!" syntax is:

1. set requires one parameter that is a=b.
   If a contains a space or something, you'll have to use the quotation marks around this parameter. Here I don't see any

2. !line:*:=!
   For this syntax, you can type 'set /?' to see the official description on using variables.
   !var! is like %var%, to get the value. But !var! means delayed expansion.

line var name

the first : variable modification mark.

**:= **:=(empty), replace the string in the variable's value matches "*:"(virtually from the string start to first : occurence) with (empty), i.e. delete the substring from start to first colon.
