Posix has specified a more powerful, albeit somewhat more cryptic, mechanism cribbed from ksh, and bash implements it.

${parameter%word}

Remove smallest suffix pattern. The WORD is expanded to produce a pattern. It then expands to the value of PARAMETER, with the smallest portion of the suffix matched by the pattern deleted.

x=file.c

echo ${x%.c}.o

–>file.o

${parameter%%word}

Remove largest suffix pattern. The WORD is expanded to produce a pattern. It then expands to the value of PARAMETER, with the largest portion of the suffix matched by the pattern deleted.

x=posix/src/std

echo ${x%%/*}

–>posix

${parameter#word}

Remove smallest prefix pattern. The WORD is expanded to produce a pattern. It then expands to the value of PARAMETER, with the smallest portion of the prefix matched by the pattern deleted.

x=$HOME/src/cmd

echo ${x#$HOME}

–>/src/cmd

${parameter##word}

Remove largest prefix pattern. The WORD is expanded to produce a pattern. It then expands to the value of PARAMETER, with the largest portion of the prefix matched by the pattern deleted.

x=/one/two/three

echo ${x##*/}

–>three

Given

a=/a/b/c/d

b=b.xxx

Like other open source software, the standard installation step are;
- configure
- make
- make install
You’ll be so lucky if this happen. Unfortunately, sometime the installation not run as we expect. At least, there are some problem that I have deal with.

DCL need gtk (gtk1 or gtk2) as preexisting requirement. You have to install it, even during

configure

process the absent of gtk would not consider as error. That is the first important notice upon successful installation.

Next step is

make

process which is easy thing to do. Only type make and everything will go automatically. But this process have gone to far. A single error in compilation would not make the process stop. So don’t get be wrong if you see the installation has finish. Just check again and make sure there is no failed compilation.

That’s it for this time. I hope I can add another info later.

To solve this problem you can easily modify the irb script by added $LOAD_PATH at the beginning of script. For example like my modified irb script below:

#!/usr/bin/ruby1.8
#
# irb.rb - intaractive ruby
# $Release Version: 0.9.5 $
# $Revision: 11708 $
# $Date: 2007-02-13 08:01:19 +0900 (Tue, 13 Feb 2007) $
# by Keiju ISHITSUKA(keiju@ruby-lang.org)
#
$LOAD_PATH << '/home/jpatiani/lib/ruby/1.8'
require "irb"

if __FILE__ == $0
IRB.start(__FILE__)
else
# check -e option
if /^-e$/ =~ $0
IRB.start(__FILE__)
else
IRB.setup(__FILE__)
end
end


Thank God found this simple solution. I found it here

Seem the picture not coming up. Daaa, what wrong with this.

Everything just work fine and I can sleep well tonight.

PS:
when set relayhost in postfix use IP don’t use hostname.
If hostname is used, it will be error with message “Name or service not known”.
At least it’s happen to me.

Well, that was the bad news. Fortunately, not only bad news I also have the good one. My script from last Wednesday work well. The script for the lazy person that what I call this. The script mainly contains wget and sed command. Small script, but good one.
This script divided into to two part. First part, download full index.html with contains list name of file in current folder. Second, manipulate the index.html and then download the needed file.

May be this step seem to be complicated. Because wget actually can choose what we want to download. But in this case I don’t see this work. So this tricky work fine for me.

So I brave my heart not just only fill the missing ext but also completely change the system. The newest php installed in the SLES 9, at that moment php 5.2.6 was the newest.

Before install php there is important note that newbies like I’m need to pay attention. That is if we want to install complete package, first of all we need install library. For example, if we want install mhash support so we need to install mhash-devel first. And so on.

For my SLES the configuration I used is
./configure --prefix=/usr/local/php5 --with-apxs2=/usr/sbin/apxs2-prefork --with-libxml-dir=/usr/local/libxml2 --enable-calendar --with-curl --with-zlib --with-jpeg-dir=/usr --with-gd --with-png-dir=/usr --with-freetype-dir=/usr --with-ttf --with-mysql --with-iconv --with-imap --with-imap-ssl --with-gettext --with-bz2 --with-curl --with-mcrypt --with-mhash --with-mime_magic --with-ncurses --with-openssl --with-readline --with-mm --with-snmp --enable-sockets --enable-ftp --enable-zip --enable-cli --enable-fastcgi --enable-cgi --with-libdir=lib64 2>&1 | tee build.log

Of course the directory up to your system. Another note is that php5 need newer version of libxml2. We need install newer libxml2 to complete the requirement.

When everything work smoothly, next step is configure apache2 to support php5. This can be done by edit the /etc/sysconfig/apache2 and add php5 in variable APACHE_MODULES. Here is for the example APACHE_MODULES="suexec access actions alias auth auth_dbm autoindex cgi dir env expires include log_config mime negotiation setenvif userdir ssl python php5" And remember not to mess with php4.

Next, copy the libphp5.so in the directory pointed in file /etc/apache2/sysconfig.d/loadmodule.conf.

And then we need conf file to make sure that php5 will be loaded. The file is called php5.conf and put in /etc/apache2/conf.d. The file contains following line:

<IfModule mod_php5.c>
AddType application/x-httpd-php .php .phtml .html .htm
AddType application/x-httpd-php-source .phps
AddHandler application/x-httpd-php .php4
AddHandler application/x-httpd-php .php5
AddHandler application/x-httpd-php .php
AddHandler application/x-httpd-php-source .php4s
AddHandler application/x-httpd-php-source .php5s
AddHandler application/x-httpd-php-source .phps
DirectoryIndex index.php4
DirectoryIndex index.php5
DirectoryIndex index.php index.html index.htm
</IfModule>


And then restart apache service:
/etc/init.d/apache2 restart

Voila, your php5 have just installed. To make sure you can test with php function phpinfo.

php5 -: symbol lookup error: -: undefined symbol: xmlParserInputBufferCreateFilenameDefault

Well that was very frustrate. And all must be turn back to normal. No other choice better than downgrade the glibc. Suddenly everything lost control and system became unstable. The message was:

INIT: cannot execute "/sbin/mingetty"
INIT: cannot execute "/sbin/mingetty"
INIT: cannot execute "/sbin/mingetty"
INIT: cannot execute "/sbin/mingetty"
INIT: cannot execute "/sbin/mingetty"
INIT: cannot execute "/sbin/mingetty"
INIT: cannot execute "/sbin/mingetty"
INIT: cannot execute "/sbin/mingetty"
INIT: cannot execute "/sbin/mingetty"
INIT: cannot execute "/sbin/mingetty"
INIT: Id "1" respawning too fast: disabled for 5 minutes

Well well well another problem rose . Time to rest.

And today, after I feel this is my day because I can solve the CMAQ installation that has been long time troubled one of my lab friend, Hengki, I came to server room to reinstall the server. But after I check that there is option for repair the system I cancel reinstall plan. With just single simple click to “Automatic Repair” everything back normal. Thank God.
And I just more Luv SuSE

USER userid
This must be the first command after the connect. Supply your e-mail userid (not the full e-mail address). Example: USER john.smith

PASS password
This must be the next command after USER. Supply your e-mail password. The password may be case sensitive.

The following commands may be used as needed:

STAT
The response to this is: +OK #msgs #bytes Where #msgs is the number of messages in the mail box and #bytes is the total bytes used by all messages. Sample response: +OK 3 345910

LIST
The response to this lists a line for each message with its number and size in bytes, ending with a period on a line by itself. Sample response:
+OK 3 messages
1 1205
2 305
3 344400
.

RETR msg#
This sends message number msg# to you (displays on the Telnet screen). You probably don’t want to do this in Telnet (unless you have turned on Telnet logging). Example: RETR 2

TOP msg# #lines
This is an optional POP3 command. Not all POP3 servers support it. It lists the header for msg# and the first #lines of the message text. For example, TOP 1 0 would list just the headers for message 1, where as TOP 1 5 would list the headers and first 5 lines of the message text.

DELE msg#
This marks message number msg# for deletion from the server. This is the way to get rid a problem causing message. It is not actually deleted until the QUIT command is issued. If you lose the connection to the mail server before issuing the QUIT command, the server should not delete any messages. Example: DELE 3

RSET
This resets (unmarks) any messages previously marked for deletion in this session so that the QUIT command will not delete them.

QUIT
This deletes any messages marked for deletion, and then logs you off of the mail server. This is the last command to use. This does not disconnect you from the ISP, just the mailbox.

May help every body.
