NAME

ljack - monitor system logs

SYNOPSIS

ljack [ -n ] file1 [[ -n ] file2 ... ]

DESCRIPTION

Ljack (short for "lumberjack") runs under the SunView windowing environment. It monitors one or more logfiles, optionally alerting the user when an update takes place. The files specified on the command line should be readable by the user; if a file is not readable, no subwindow will be created for it.

Ljack's display is organized into a number of equal-sized subwindows, one for each file. The subwindows are standard text-editing windows (see textedit(1)) that can be scrolled and searched as usual. New information is added to the appropriate subwindow as it appears in a file, and the display scrolls to show the new data if necessary.

If ljack is in icon form when a file is updated, an animated axe chops at the log in the icon to inform the user that something new has arrived. The axe disappears when the icon is opened and closed again.

Up to sixteen files can be viewed; in some versions of SunOS (3.x and lower) there are not enough file descriptors to view more than six files.

OPTION

-n: If a file is preceded by a -n argument, the axe will not appear when the file is updated.
