in thread Reading AND writing on BSD?

but im reading everything into a variable first, then seek()ing to the beginning of the file to write to it, then the close() should automatically flush the write buffer, shouldnt it? so where would I put the flush()? the code is as follows:
open(FH,"+<file.txt") || die($!); @fh = <FH>; # operate on file contents, store shit to print in $fh seek(FH,0,0); print FH $fh; close(FH);

autoflushing..

    Have you confirmed that $fh contains data? If there is a bug in the code you omitted and $fh is undefined then the file will not be changed.

    Just a guess, do you mean
    print FH @fh;

    Try some opening one file for reading and one for writing. Does it make it there?
