Yes. Within a script, use $^I.

local $^I   = '.bak'    # use " = '';" for no backup
local @ARGV = ($file);  # put your file(s) here
while <> {
     s/pattern/replacement/;
     print
}

perlvar(1) has a tidbit. See also Programming Perl (Wall, 
Christiansen & Orwant), Chapter 2, section on Special Variables; and 
Perl Cookbook (Christiansen & Torkington), Example 7.9.

Enjoy.
