Re^3: opening file for editing

you can do this in two steps:

read open
dump all to a variable (in memory)
apply a substitution to this variable
close
re-open the file, now for writing
print the changed variable to the file (overwrite the whole file)
and close again

No temp files here, and your file is updated as you want. Use perldoc for the details.
