Anyone know how to remove a certain string from a file
without having the create a tmp file.

i.e sed "s/\.//g" simat.dat strip all . 's from simat.dat

if we use

cat simat.dat | sed "s/\.//g" > simat.dat
then we end up with simat.dat being empty and 0 bytes.

There must be a nice way to do this without having to 
create a pooy tmp file.

?? erm ermy erm

Simon saus man. :)
