How to use wget to download globbing files

You want to download all the GIFs from a directory on an HTTP server.
You tried wget http://www.server.com/dir/*.gif, but that didn't work
because HTTP retrieval does not support globbing.

In that case, use:
wget -r -l1 --no-parent -A.gif http://www.server.com/dir/

More verbose, but the effect is the same. -r -l1 means to retrieve
recursively, with maximum depth of 1. --no-parent means that refer-
ences to the parent directory are ignored, and -A.gif means to down-
load only the GIF files. -A "*.gif" would have worked too.
>>From mget manual.

You can use globbing for downloading globbing files from ftp servers.
wget ftp://ftp.server.com/dir/*.gif

3.Solution
Applications containing more than 2 GB of static data should be built with
"-mcmodel medium -shared-intel" options.
In my application an huge array as following to hold all data needs is used.
---------------------------------------------------------------------------
INTEGER, PARAMETER :: MAXNI = 360, #longtitude
& MAXNJ = 180, #latitude
& MAXNP = 50, #height
& MAXNT = 24, #hours
& MAXNV = 10, #variables

REAL :: meadia(MAXNI,MAXNJ,MAXNP,MAXNT, MAXNV) ! org conc
----------------------------------------------------------------------------
The static array will be:
360×180×50×24×10×4(4bytes/real data type) = 3110,400,000bytes about 3.1G
After specified "-mcmodel medium -shared-intel" the compiler options, the error disappeared.

NOTE：
1)It seems that this error only occurs on AMD 64 CPU architecture. I successed compiling the same application on IA 64 CPU without getting an error.

2)The same error occurred even if specified the "-mcmodel medium -shared-intel" options. Check your sizes of all your static arrays again to make sure they are not too huge.
Theoretically you can not use a static array more than 4G in AMD/IA 32 CPU,
16G in AMD/IA 64 CPU.

Print to pdf in command line

1.install cups-pdf printer

1)Download the cups-pdf Package
search for the cups-pdf package for your version of openSUSE.
Next to the first result, click "1-Click Install" and follow the steps to install the cups-pdf package.

2)Set cups-pdf File Permission
Since version 1.2, cups don't support option "RunAsOption" anymore but cups-pdf needs root privileges in order to modify file ownerships.

sudo chmod +s /usr/lib/cups/backend/cups-pdf

3)Install the Printer
(1).Open the CUPS Administration page using a web browser like Firefox (visit http://localhost:631/admin, note: the CUPS service must be running, see System Services (runlevel).)
(2). Select the Administration tab and click Find New Printers
(3). You should see Virtual PDF Printer (CUPS-PDF), click Add This Printer
(4). Click Continue
(5). In the next screen MAKE/MANUFACTURER FOR CUPS-PDF, don't select a printer but in the OR Provide a PPD File section, provide the name of the driver by browsing to /usr/share/cups/model/CUPS-PDF.ppd then click Add Printer.
(6). Use the "root" username and password (or any username with CUPS admin rights) when prompted finish adding the new printer.

4)Configuration Options
PDF Output Location, the default location for the PDF files is
/var/spool/cups-pdf/yourusername/

To change this, edit the /etc/cups/cups-pdf.conf file.
In this case, to the Desktop of the user.
Out ${HOME}/Desktop

2.Print pdf from command line ( Shell file )

#!/bin/csh
set printer=cups-pdf

if( $1 != "" ) then
lpr -P$printer $1
echo ${1} sent to $printer ... OK!
else
echo PDF Print: No filename defined!
endif

save shell script above to pdfprint.bash and make it executable by
chmod +x pdfprint.bash

use pdfprint.bash filename to print.PDF files are output to you desktop.


3.Supplement
At first I meant to use kprinter to print to file(PDF) function.
You can use kprinter at command line.
example:
kprinter --nodialog -d printername filename
more help can be found by using:
kprinter --help

But I can't find the right printername for "print to file (PDF)" option in the kprinter dialog . :-(

It is said that the printer name is the name that appears in the print dialog. If you want to print to PDF, then it's "Print to File (PDF)", there's no easy shortcut.
But it still doesn't work. The error message says that "not found specified or default printer".

[HOWTO]Change ls command default colors

1.Test colors supported
This shell script shows all standard colour combinations on the current console.
If no colours appear, your console does not support ANSI colour selections.

    #!/bin/bash
    # Display ANSI colours.
    #
    esc="\033["
    echo -e "\t  40\t   41\t   42\t    43\t      44       45\t46\t 47"
    for fore in 30 31 32 33 34 35 36 37; do
      line1="$fore  "
      line2="    "
      for back in 40 41 42 43 44 45 46 47; do
        line1="${line1}${esc}${back};${fore}m Normal  ${esc}0m"
        line2="${line2}${esc}${back};${fore};1m Bold    ${esc}0m"
      done
      echo -e "$line1\n$line2"
    done

2.Customize your ls output colors
first copy /etc/DIR_COLORS to HOME/.dir_colors.
then modify .dir_colors to your preferred themes(see comments in files).
by default, bash will use your cutomized colors next time when you open a new shell window.

NOTE: dircolors -p to view current color scheme.

Points to Speed up YaST

By default, Yast with activate and check update for every repository entries you setup.
So it will be faster if you disenable those default options.
Better options:
1.check update by manually, don't let YaST check it every time.
2.keep only main repositories activating, disactivate temporary repositories.
only use temporary entries when you need.

openSUSE power managerment on Toshiba laptop

0.preface


1.openSUSE power management intro
To be added.

2.setup suspend to RAM and test
Unfortunately, my Toshiba laptop is not in the s2ram whitelist.
First find out proper options that work for you.
In my case, "sudo s2ram -f" works fine. You can find some test options combinations in http://en.opensuse.org/S2ram.

Second modify opsensuse options.The default is s2ram, no other options are set in openSUSE.
sudo vi /etc/pm/config.d/s2ram
add follow lines:
S2RAM_OPTS="-f"

3.setup suspend to RAM with KPowersave
When you close laptops's lid, the default action is to lock your screen not to suspend to RAM.
You can change it by follow steps.

2.Error Message
by running the command:
mpirun -np 4 wrf.exe

The following errors occurred:
rank 3 in job 1 nox_48738 caused collective abort of all ranks
exit status of rank 3: killed by signal 11

3.Reason
before you run mpd daemon, you should set stacksize to unlimited.
To solve this problem, read on.

4. My solution memo
--------------------------------------------------------------
1.using root mpd
1)login as root to confirm if mpd is running or not.
if not running then
(1)check current stacksize option, make sure it's unlimited.
$bash(root's default shell):
ulimit -a
(by default, root uses bash as its shell and stacksize is,
already set to unlimited. This is the reason that mpd
running as root didn't failure.)
if stacksize is not unlimited, then
ulimit -s
to set it to unlimited.

$tcsh(or csh):
limit
if stacksize is not unlimited, then
limit stacksize unlimited to set it to unlimited or
unlimit to set all resources to unlimited.

(2)lauch mpd
mpd & or mpd --daemon

#NOTE:you may ask your sysadmin to add (1) routie to startup
scripts so that mpd will be started automatically whenever
machine reboots.

2)logout root and setup ~/.mpd.conf file.
add follow lines to .mpd.conf file in your home dir.
MPD_USE_ROOT_MPD=1

3)run mpirun in your own shell.
example:
mpirun -np 4 wrf.exe
or
mpiexec -n 4 wrf.exe
--------------------------------------------------------------
2.using your own mpd
1)login to confirm if mpd is running or not.
if not running then
(1)check current stacksize option, make sure it's unlimited.
reference(1) section above.

(2)launch mpd
mpd & or mpd --daemon
#NOTE: you can automate this step by modifying your login scripts.
Do remember mpd is resource consuming.

2)check ~/.mpd.conf.
comment out following line.
MPD_USE_ROOT_MPD=1

3)run mpirun in your own shell.
example:
mpirun -np 4 wrf.exe
or
mpiexec -n 4 wrf.exe

使用readline的VI MODE

介绍如何使用Bash的readline的EMACS模式的文章很多，但是VI模式的文章不是很多。EMACS的按键太繁琐，虽然功能强大，我倒不怎么使用。下面拼凑了一些找的的关于readlin的VI模式的文章。
1. BASH中切换到readline的VI模式
set -o vi

2. GDB中切换的readline的VI模式
C+M+j(Ctrl+Alt+j)快捷键。
或者vi ~/.gdbinit文件， 添加
set editing-mode vi

3. readline的VI模式常用快捷键
