print
print - output a list to a filehandle
print FILEHANDLE LIST
print LIST
print
Prints a string or a comma-separated list of strings. Returns TRUE
if successful. FILEHANDLE may be a scalar variable name, in which case
the variable contains the name of or a reference to the filehandle, thus introducing one
level of indirection. (NOTE: If FILEHANDLE is a variable and the next
token is a term, it may be misinterpreted as an operator unless you
interpose a + or put parens around the arguments.) If FILEHANDLE is
omitted, prints by default to standard output (or to the last selected
output channel--see
select()
). If LIST is also omitted, prints
$_
to
STDOUT. To set the default output channel to something other than
STDOUT use the select operation. Note that, because print takes a
LIST, anything in the LIST is evaluated in a list context, and any
subroutine that you call will have one or more of its expressions
evaluated in a list context. Also be careful not to follow the print
keyword with a left parenthesis unless you want the corresponding right
parenthesis to terminate the arguments to the print--interpose a + or
put parens around all the arguments.
Note that if you're storing FILEHANDLES in an array or other expression,
you will have to use a block returning its value instead
