       linux_logo  is  a  program  that  generates  a  color ANSI picture of a
       penguin which includes some system information obtained from the  /proc

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

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

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

       ·   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 \

       The  default  banner  format  displays  the  following  on the author’s

         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
       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

       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

           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
                                    "-L random_ce" picks a random classic logo
                                    "-L random_ee" picks any logo, etc.


       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


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