If output redirected to file, you can still force + it into interactive mode by this option. + +-o Reconnect on overflow. The behaviour of utility on overflow is same + as for tty close. For more info see snp(4). + +-t Timestamp.Print date and time each time, tty watching started. + + The <tty name> is one of following types: + ttyp?,ttyq?,ttyr? - pseudo tty devices. + ttyv? - virtual ttys (syscons). + tty0?,ttyd? - serial lines. + Each name can be preceeded by "/dev/". + Also recognized: + pty[NUM] - pseudotty's. + vty[NUM] - virtual ttys. + sio[NUM] - serial lines. + + While running interactive, all user input discarded except : + Ctrl+C - Exit watch. + Ctrl+X - Change attached tty. + Ctrl+W - Clear screen. + +.Sh SEE ALSO +snp(4),pty(4),sio(4) +.Sh BUGS +No terminal emulation involved,all user output comes to the screen as-is. +.Sh HISTORY +FreeBSD 2.1,By Ugen J.S.Antsilevich <ugen@NetVision.net.il> |
