Hey there A. M.

Would a flush(); be useful?

    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);

      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?

    AFAIK flush(); isnt a default perlfunc...
