      for i in *; do
 	sed -e "s/Have a good day/jump off a cliff/g" $i > tmp
 	mv tmp $i
      done
      
Better yet, put it in a file like this:

#!/bin/bash
for f
 do
 sed -e "s/Have a good day/jump off a cliff/g" $f > tmp$$
 mv tmp$$ $f
 done
 
Then you can invoke that file with a filename or a wildcard:

$ foo A B C
$ foo *
$ foo /some/path/or/other/bar[1-9][0-9]*.txt
