Therefore I dont think we can do that. check perldoc -f open for "+", ">", ">>" modifiers. and, may be you should check 'seek' function. perldoc -f seek "You can't usually use either read-write mode for updating textfiles, since they have variable length records. See the -i switch in the perlrun manpage for a better approach." - you are warned. as usual, you can use temporary files as a i/o buffer.
