Question

I’ve two perl scripts, both of them wait for user to enter some input as below,

Does both of them are same ?
Does “STDIN” written in <> are just to for user-readability of code ?
If not please tell me the differences.

a) $in = <STDIN>;

b) $in = <>;

Answer 1

The form <FILEHANDLE> will only read from FILEHANDLE.

The form <> will read from STDIN if @ARGV is empty; or from all the files whose names are still in @ARGV which contains the command line arguments passed to the program.
