Displays a given file anywhere on your X11 root window, i.e. it is kind of tail -f for multiple files
using your desktop background as output window.
All non-option arguments on the command line are files to be logged. A null desc (example:
"/var/log/messages,red,") will prevent the printing of a description and the []'s.
GeneralOptions--colorCOLOR
Use COLOR as default.
--font|-fnFONTSPEC
Use font FONTSPEC. This can be either a fixed width font like -fnfixed or any font using -fn
'-*-*-*-*-*-*-*-*-*-*-*-*-*-*' with the appropriate fields filled out (see xfontsel). Specifying
a different FONTSPEC before each filename will cause each file to be displayed in a different
font.
-f|--fork
Forks to the background.
--reverse
Display the files in reverse order, with the newest lines at the top.
--whole
Only display whole lines. If the last line of a file doesn't yet end with a newline character then
wait until it does before displaying it. This is the default if more than one file is being
displayed.
--partial
This is the opposite of the --whole option (see above). It displays lines even if they don't yet
have a newline at the end. This is the default if only one file is being displayed.
--update
Update partial lines 'in place' if they are still on the screen when they are updated in their
files. Using --update automatically turns on --partial.
--contSTRING
When partial lines are broken into two lines in the display, prefix the 2nd line with STRING.
Defaults to "|| ". Specify the "--whole" argument to ensure partial lines are never displayed, or
specify "--update" to attempt to "repair" broken lines in-place.
--cont-colorCOLOR
Use COLOR when displaying the continuation string (as optionally specified with the --cont option
above).
--wordwrap
The default behaviour is to fit as much as possible onto each line of output, even if this means
splitting a word between one line and the next. The --wordwrap argument splits lines at spaces if
possible.
--justify
After wrapping long lines, attempt to justify the text to produce a smooth right-hand margin.
Implies --wordwrap.
--reloadSECCOMMAND
Re-display the file(s) and run COMMAND every SEC seconds. The default is to never re-display the
file(s).
--shade
Add black shading to the font.
--outline
Add a black outline to the font (making redraws quite a bit slower).
--minspace
Use minimum linespace even when using shading or outlining. This might result in leftover pixels
(dependign on font and logfile content).
--noflicker
Use slower but flicker-free update.
--noinitial
Don't display the end of the file(s) initially.
--windowed
Create a new window instead of reusing the root window. The newly created window covers the whole
screen, puts itself behind all other windows and and does not accept events. Use this option if
you use a compositing manager suihc as xcompmgr or compton, as the compositing extension has been
very badly designed and cannot handle root windows correctly.
-idID Use the given window ID for output instead of the root window.
-i|--intervalSECONDS
Use the specified sleeping interval between checks instead of the default 2.4 seconds. Fractional
values are OK.
-V Print version information.
--frame
Draw a frame around the selected area. This is useful when trying to find the perfect geometry.
