Re^2: detect input available from command line by mifflin (Curate) on Mar 10, 2011 at 21:51 UTC
What if the input is not coming from @ARGV but from stdin? example: `$ ./testprog -t testing@testing.com -s test5 <<EOT; > stuff > typed > in > here > EOT` [download] In this case @ARGV is empty but there is still something to read. How would I detect this?	[reply] [d/l]

You could test `if (@ARGV or !-t STDIN and !eof()) { while (<>) { ...` [download] (but any non-input file arguments would need to be removed from @ARGV first, of course) This should work with input file arguments on the command line, heredoc input (`<<`), input redirect (`<`), and piping into the program (`\|`). Update: actually, I think you don't even need the `eof()`.	[reply] [d/l] [select]

I have a program that may try to get data from the command line using What if the input is not coming from @ARGV but from stdin? If the input is coming from STDIN then it is not on the command line.	[reply]
