The -p switch uses a while loop so your example above is equivalent to:
perl -e'while ( <> ) { print "goat \n" } continue { print }'
And if no file names are provided then <> reads from STDIN. If you just want
to print a string then don't use the -p switch:
perl -e'print "goat \n"'
Or:
perl -le'print "goat"'
