in reply to Reading AND writing on BSD?

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...

    ... Quidquid perl dictum sit, altum viditur.
