The [[variadic?]] print function is used to produce simple standardized output. A [[comma?]] separated [[list?]] of items for output is provided in the [[argument?]] list.
print "Hello"
If the print function is given no [[argument?]] list, then it will by default output the current record:
# These two commands are equivalent print $0 print
Note that the default action within a rule is to print all [[line?]]s that match the pattern. This means that an action to just print a matching line can be omitted altogether.
