systat is aBSD UNIXconsole application for displaying system statistics in fullscreen mode usingncurses/curses. It is available on, and by default ships in the base systems of,FreeBSD,NetBSD,OpenBSD andDragonFly BSD.[1][2][3][4] It was first released as part of4.3BSD in 1986; 39 years ago (1986).[5]
Both internally and in theinterface of the user the utility consists of several distinct modules andtabs, referred to as "displays" in FreeBSD, NetBSD and DragonFly, and "views" in OpenBSD, which are automatically refreshed every specified number of seconds.[5] These modules cover all system components, including statistics resemblingvmstat,iostat andnetstat in all of the BSDs, as well aspf andsensors views in some of the BSDs.[6][7] The systat utility is notably absent fromOS X, where a GUI-basedActivity Monitor performs similar functions.
