Not true on all systems - buffering varies on different target devices, system calls and OS's. UNIX 'write (2)' to a disk file is not buffered - unlike the stdio interface (see last comment below). > My problem is I have to do a kill -9 at the end.

If all you want to do is make sure your data is unbuffered, then turn off the buffering after opening the file. You can select it and unbuffer it using: $oldh = select (FH); $| = 1; select ($oldh); or one step version: select ((select (FH), $| = 1)[0]); Using syswrite will also bypass any buffered IO since it uses the 'write' system call, but be careful mixing it with stdio (non-'sys') functions. -- ,-/- __ _ _ $Bill Luebkert Mailto:[EMAIL PROTECTED] (_/ / ) // // DBE Collectibles Mailto:[EMAIL PROTECTED] / ) /--< o // // Castle of Medieval Myth & Magic http://www.todbe.com/ -/-' /___/_<_</_</_ http://dbecoll.tripod.com/ (My Perl/Lakers stuff) _______________________________________________ Perl-Unix-Users mailing list Perl-Unix-Users@listserv.ActiveState.com To unsubscribe: http://listserv.ActiveState.com/mailman/mysubs
