<H2>DESCRIPTION</H2> |
| 83 |
|
|
|
| 84 |
|
|
Displays a given file anywhere on your X11 root window, i.e. it is kind of tail -f for multiple files |
| 85 |
|
|
using your desktop background as output window. |
| 86 |
|
|
<P> |
| 87 |
|
|
|
| 88 |
|
|
All non-option arguments on the command line are files to be logged. A |
| 89 |
|
|
null desc (example: "/var/log/messages,red,") will prevent the printing of |
| 90 |
|
|
a description and the []'s. |

<DL COMPACT> |
| 97 |
|
|
<DT><B>--color</B><I> COLOR</I> |
| 98 |
|
|
|
| 99 |
|
|
<DD> |
| 100 |
|
|
Use COLOR as default. |
| 101 |
|
|
<DT><B>--font | -fn</B><I> FONTSPEC</I> |
| 102 |
|
|
|
| 103 |
|
|
<DD> |
| 104 |
|
|
Use font FONTSPEC. This can be either a fixed width font like <B>-fn</B><I> |
| 105 |
|
|
fixed</I> or any font using <B>-fn </B>'<I>-*-*-*-*-*-*-*-*-*-*-*-*-*-*</I>' with |
| 106 |
|
|
the appropriate fields filled out (see xfontsel). Specifying a |
| 107 |
|
|
different FONTSPEC before each filename will cause each file to be |
| 108 |
|
|
displayed in a different font. |
| 109 |
|
|
<DT><B>-f | --fork</B> |
| 110 |
|
|
|
| 111 |
|
|
<DD> |
| 112 |
|
|
Forks to the background. |
| 113 |
|
|
<DT><B>--reverse</B> |
| 114 |
|
|
|
| 115 |
|
|
<DD> |
| 116 |
|
|
Display the files in reverse order, with the newest lines at the top. |
| 117 |
|
|
<DT><B>--whole</B> |
| 118 |
|
|
|
| 119 |
|
|
<DD> |
| 120 |
|
|
Only display whole lines. If the last line of a file doesn't yet end |
| 121 |
|
|
with a newline character then wait until it does before displaying |
| 122 |
|
|
it. This is the default if more than one file is being displayed. |
| 123 |
|
|
<DT><B>--partial</B> |
| 124 |
|
|
|
| 125 |
|
|
<DD> |
| 126 |
|
|
This is the opposite of the <B>--whole</B> option (see above). It displays |
| 127 |
|
|
lines even if they don't yet have a newline at the end. This is the |
| 128 |
|
|
default if only one file is being displayed. |
| 129 |
|
|
<DT><B>--update</B> |
| 130 |
|
|
|
| 131 |
|
|
<DD> |
| 132 |
|
|
Update partial lines 'in place' if they are still on the screen when |
| 133 |
|
|
they are updated in their files. Using <B>--update</B> automatically turns on |
| 134 |
|
|
<B>--partial</B>. |
| 135 |
|
|
<DT><B>--cont</B><I> STRING</I> |
| 136 |
|
|
|
| 137 |
|
|
<DD> |
| 138 |
|
|
When partial lines are broken into two lines in the display, prefix |
| 139 |
|
|
the 2nd line with STRING. Defaults to "<I>|| </I>". Specify the "<B>--whole</B>" |
| 140 |
|
|
argument to ensure partial lines are never displayed, or specify "<B>--update</B>" |
| 141 |
|
|
to attempt to "repair" broken lines in-place. |
| 142 |
|
|
<DT><B>--cont-color</B><I> COLOR</I> |
| 143 |
|
|
|
| 144 |
|
|
<DD> |
| 145 |
|
|
Use COLOR when displaying the continuation string (as optionally |
| 146 |
|
|
specified with the <B>--cont</B> option above). |
| 147 |
|
|
<DT><B>--wordwrap</B> |
| 148 |
|
|
|
| 149 |
|
|
<DD> |
| 150 |
|
|
The default behaviour is to fit as much as possible onto each line of |
| 151 |
|
|
output, even if this means splitting a word between one line and the |
| 152 |
|
|
next. The <B>--wordwrap</B> argument splits lines at spaces if |
| 153 |
|
|
possible. |
| 154 |
|
|
<DT><B>--justify</B> |
| 155 |
|
|
|
| 156 |
|
|
<DD> |
| 157 |
|
|
After wrapping long lines, attempt to justify the text to produce a |
| 158 |
|
|
smooth right-hand margin. Implies <B>--wordwrap</B>. |
| 159 |
|
|
<DT><B>--reload</B><I> SEC COMMAND</I> |
| 160 |
|
|
|
| 161 |
|
|
<DD> |
| 162 |
|
|
Re-display the file(s) and run COMMAND every SEC seconds. The |
| 163 |
|
|
default is to never re-display the file(s). |
| 164 |
|
|
<DT><B>--shade</B> |
| 165 |
|
|
|
| 166 |
|
|
<DD> |
| 167 |
|
|
Add black shading to the font. |
| 168 |
|
|
<DT><B>--outline</B> |
| 169 |
|
|
|
| 170 |
|
|
<DD> |
| 171 |
|
|
Add a black outline to the font (making redraws quite a bit slower). |
| 172 |
|
|
<DT><B>--minspace</B> |
| 173 |
|
|
|
| 174 |
|
|
<DD> |
| 175 |
|
|
Use minimum linespace even when using shading or outlining. This might result in |
| 176 |
|
|
leftover pixels (dependign on font and logfile content). |
| 177 |
|
|
<DT><B>--noflicker</B> |
| 178 |
|
|
|
| 179 |
|
|
<DD> |
| 180 |
|
|
Use slower but flicker-free update. |
| 181 |
|
|
<DT><B>--noinitial</B> |
| 182 |
|
|
|
| 183 |
|
|
<DD> |
| 184 |
|
|
Don't display the end of the file(s) initially. |
| 185 |
|
|
<DT><B>--windowed</B> |
| 186 |
|
|
|
| 187 |
|
|
<DD> |
| 188 |
|
|
Create a new window instead of reusing the root window. The newly created window |
| 189 |
|
|
covers the whole screen, puts itself behind all other windows and and does not accept |
| 190 |
|
|
events. Use this option if you use a compositing manager suihc as xcompmgr or compton, as |
| 191 |
|
|
the compositing extension has been very badly designed and cannot handle root windows |
| 192 |
|
|
correctly. |
| 193 |
|
|
<DT><B>-id</B><I> ID</I> |
| 194 |
|
|
|
| 195 |
|
|
<DD> |
| 196 |
|
|
Use the given window ID for output instead of the root window. |
| 197 |
|
|
<DT><B>-i | --interval</B><I> SECONDS</I> |
| 198 |
|
|
|
| 199 |
|
|
<DD> |
| 200 |
|
|
Use the specified sleeping interval between checks instead of the |
| 201 |
|
|
default 2.4 seconds. Fractional values are OK. |
| 202 |
|
|
<DT><B>-V</B> |
| 203 |

|
| 204 |

<DD> |

Print version information. |

|
|
<DT><B>--frame</B> |
| 207 |
|
|
|
| 208 |
|
|
<DD> |
| 209 |
|
|
Draw a frame around the selected area. This is useful when trying to |
| 210 |
|
|
find the perfect geometry. |

Some desktop environments open a virtual root window and make it difficult to share it. If |
| 225 |
|
|
you cannot see anything after starting root-tail, try to find a setting "allow programs |
| 226 |
|
|
on desktop" or similar, or manually specify a window id. |
| 227 |
|
|
<P> |
| 228 |

|
|
Should you happen to find any bugs please fix them and send me a diff. |
