I am learning from a tutorial and it used this command type NUL > introduction.js . I searched online TYPE is a command, i know > is redirection operation and last is the name of the file. And it creates an empty file. I dont't know the function of NUL but its equivalent to dev/nul of UNIX.
But can someone summarize the whole command in parts and what is the advantage of doing this instead of echo or other commands.
In CMD help:
type /?
Displays the contents of a text file or files.
TYPE [drive:][path]filename
and NUL I think is an empty file symbol. so,
type NUL > introduction.js
reads the content of NUL "Which is an empty file", and write it to introduction.js
conclusion:
You are creating an empty introduction.js file.
