If this is merely for debugging, can't you write a wrapper that forces line buffering for a program? The wrapper could substitute your own C library functions via LD_PRELOAD, or could run the program inside a pseudotty a la 'expect'.
If it's for production use then I'm not sure it's a good idea to slow down and complicate standard libraries and/or apps for a fairly-specialized need. _______________________________________________ Bug-coreutils mailing list Bug-coreutils@gnu.org http://lists.gnu.org/mailman/listinfo/bug-coreutils
