As I understand it, <> operator will open all items in @ARGV allowing one to do a shell command line of
perl.script file1 file2 file3 and inside perl.script you only need while (<>) { ... syntax to read all the files on the command line. <> will also open STDIN if the perl script is invoked from a pipe, such as ls | perl.script So, 1. from within perl.script, how can one tell if the input stream is coming from STDIN or a file that was opened by <>? 2. If input stream is not coming from STDIN, but a file, how can one tell which file is the current file (assuming multiple files were specified on the command line)?
