-pi switches

hello

i need to detab a bunch of files in a bunch of directories.


this script:

#!/usr/bin/perl -pi
s/\t/    /;


will do what i want when a supply the files as arguments
from the commandline.

i have a script that traverse all directories from a
specfied starting point.
so when i recursively get to a new file i wish to detab that
file on the fly as if i had supplied the filename as an argument

sub recursion {
  ...
  if (-f $specfile ) {
    # detab code goes here
  }
  ...
  # next file/dir
}


is that possible still using the -i switch?
