Force the screen clear before drawing the logo.
Use custom output STRING for sysinfo. See below for more info.
Display only the system infomation.
Ignore the ~/.linux_logo and /etc/linux_logo.conf config files
Keep sysinfo flushed-left (non-centered)
Display only the logo.
Custom logo options. See LOGO SELECTION below
Shift output Num spaces to the right
Preserve cursor location
Skip the BogoMips test [ speeds up display on non-Linux platforms ].
Display an arbitrary string
Display the system uptime.
Set screen width to val
Display the load average.

PROCESSOR INFORMATION

CPUINFO

The cpuinfo supplied in /proc/cpuinfo is not always usable by linux_logo.

If the cpuinfo for your microprocessor generates ugly output, send the output from your /proc/cpuinfo to the author.

FORMAT

The format string special sequences start with # (use ## to print #). All other characters, except for \n, are printed as is.

Seq Description Output
## #
#B Bogomips 374.37
#C Compiled Date #47 Fri Jan 8 10:37:09 EST 1999
#E User Text My Favorite Linux Distribution
Displayed with -t
#H Hostname deranged
#L Load average Load average 0.04, 0.01, 0.01
#M Megahertz 188Mhz
where supported
#N Number of CPU's Two
#O OS Name Linux
#P Processor or Processors Processor
#R Ram 64M
in Megabytes
#S Plural s
#T Type of CPU K6
#U Uptime Uptime 10 hours 59 minutes
#V Version of OS 2.2.0-pre5
#X CPU Vendor AMD
\\n carriage return

Notes:

  • The letter after the # must be capitalized.
  • Options not available are silently ignored.
  • Megahertz only available on some platforms and newer kernels.
  • See defaults.h on how to have #N report in non-english numbers.
  • Plural [#S] gives nothing if there is 1 cpu, gives 's' otherwise.
  • The "-y" and "-u" [display uptime and load average] command line options don't affect the output if a custom format is used.

The default banner format is:

"#O Version #V, Compiled #C\n \
#N #M#X#T Processor#S, #R RAM, #B Bogomips Total\n \
#H\n"

The default banner format displays the following on the author's computer:

Linux Version 2.2.0-pre5, Compiled #47 Fri Jan 8 10:37:09 EST 1999
One 188MHz AMD K6 Processor, 64M RAM, 374.37 Bogomips Total
deranged
Another example would be:

linux_logo -F "Redhat Linux 5.2\nKernel Version #V\n#U\n#L\n"

which would display:

Redhat Linux 5.2
Kernel Version 2.2.0-pre5
Uptime 11 hours 4 minutes
Load average 0.00, 0.00, 0.00

LOGO SELECTION

The -L command line option is used to choose which logo to use.

  • "-L list" will list all of the logos available
  • "-L NAME" will display the logo with name NAME.
  • "-L NUM" will display logo with number NUM (deprecated)
  • "-L random_xy" will pick a logo at random, with criteria xy.


When you replace x with the letter:
b : pick a random banner mode logo
c : pick a random classic mode logo
e : pick a logo from either banner or classic


When you replace y with the letter:
a: pick a random ascii logo
n: pick a non-ascii logo
e: pick either type of logo


So to summarize:
"-L random_ba" picks a random ascii banner,
"-L random_ce" picks a random classic logo
"-L random_ee" picks any logo, etc.

DEBIAN

The Debian pre-packaged version of linux_logo includes the Debian logo in addition to the 'Classic' and 'Banner' logos. The Debian logo is the default logo unless one of the other logos is specified on the command line.

CONFIG FILES

~/.linux_logo and /etc/linux_logo.conf can be filled with command line options and will be parsed before the actual command line
