Re: Re: 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);

You may want to look into autoflushing.. How do I flush/unbuffer an output filehandle? Why must I do this?.	[reply]

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.	[reply]

Just a guess, do you mean `print FH @fh;` [download] Try some opening one file for reading and one for writing. Does it make it there?	[reply] [d/l]
