Sorry my reply button keeps defaulting to the person  
instead of the list, oh to be rid of this crappy webmail  
soon.....

Just thought it would be useful to call from scripts etc.. 
though your right about righting it a s a seperate program 
etc.

just be:  
   
> $ ls | perl -e '$p = shift @ARGV; while (<>) {print if  
/$p/}' Foo  
 
 
Unfortunately this doesnt work perl assumes the Foo to be 
a file for interpreting, i found the -s option but that 
doesnt seem to work either.. its probably more useless 
than i thought anyway :) 
 
Thanks
