DESCRIPTION
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 comamnd line are files to be
logged. A null desc (example: "/var/log/messages,red,") will
prevent the printing of a description and the []'s.
General Options
- --color COLOR
- Use COLOR as default.
- --font | -fn FONTSPEC
- 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.
- --cont STRING
- 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-color COLOR
- 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.
- --reload SEC COMMAND
- 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.
- -id ID
- Use the given window ID for output instead of the root window.
- -i | --interval SECONDS
- 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.
EXAMPLE
root-tail -g 800x250+100+50 -font 10x20 /var/log/messages,green
-font 12x24 /var/log/secure,red,'ALERT'
BUGS
Some desktop environments open a virtual root window and make it
difficult to share it. If you cannot see anything after starting
root-tail, try to find a setting "allow programs on desktop" or
similar, or manually specify a window id.
Should you happen to find any bugs please fix them and send me a
diff.
