multiple conversion to lowercase

This is a modified version of my script to change extensions, for lowercase (or uppercase inverting in script) multiple files in a directory recursively.

for i in $(find . -type f);
do mv $i $(echo $i | tr "[:upper:]" "[:lower:]");
done

hope to be useful as usual.

good work!

MYSQL wont startup

Today, mysql wont startup and dont know why (or maybe!)
First of all I looked at "/var/lib/mysql/<\your host name\>.err" log and this was the error:

Fatal error: Can't open privilege tables: Can't find file: 'host.MYI' (errno: 2)

The problem is the file was there (/var/lib/mysql/mysql).
The solution is delete /var/lib/mysql/mysql wit command rm -fR,
type rcmysql start and the folder will be recreated.
You'll lost all users but mysql will be up and running! Now you have to reset the root password: mysqladmin -u root password

hope to have been useful again!

P.S.
I forgot... the error was my fault ... I played too much with phpmyadmin.
Machines do always what we want they do!

Multiple rename with find command!

I've done this shell script for multiple rename files not in same folder
(for doin that, simply use rename command) using the combination between mv and find in this way:

for i in $(find / -name *.ext1);
do mv $i $(echo $i | cut -f1 -d.).ext2;
done

in the specific, this change an extension of a file (ext1) in one another (ext2).
feel free to modify it to match your needs.

bluetooth and SuSE 9.1

It costed to me a lot of work, but finally I got IT!
My bluetooth phone work and I can browse it.

First of all, connect your bluetooth.usb.key directly on usb port without using hubs or will not work (dont know why but I'll solve it in future).

UPDATE the deafault kdebluetooth installed with your suse wit this one kdebluetooth
because it lacks a lot of necessary files you need for make it work.

After that, start kbluetoothd and you'll have an icon in system proces pannel click on it and it will show u the services disposable on your phone. that's all (well ... there are a lot of things to learn so read here: kde-bluetooth.sourceforge.net)!

Tips Installing software on SuSE 9.1

To install RPM files with Yast from command line, type this : yast -i <\packagetoinstall\>.rpm

If you downloaded source code from a program (tar.gz files) you can quickly make an RPM file from it.
To do this, first of all install the package "checkinstall", then unpack your source package and cd to the directory where you unpacked the tar.gz file.
Run the following commands:

./configure
make
checkinstall #instead of make install

When finished, you'll find your RPM in /usr/src/packages/RPMS/i686

Now you can install it where you want with yast - i <\packagetoinstall\>.rpm or with rpm -i <\packagetoinstall\>.rpm. This allows your to easily uninstall it afterwards.

Asus L3500 Power Management on SuSE 9.1

Today, I discovered that power management on my asus doesn't function properly and that I can configure extra buttons and leds on my laptop trought powersave (default acpi manager for suse).
Now I'll show you how-to do it!

SUSPEND AND STANDBY

edit '/etc/powersave.conf'. Right at the end there are two lines:
POWERSAVED_DISABLE_USER_SUSPEND=yes POWERSAVED_DISABLE_USER_STANDBY=yes
modify it to 'no'

ASUS_ACPI

acpi4asus (kernel module for asus special keys and leds) is included in the kernel (from 2.6). Just load the module 'asus_acpi' since startup, editing the file '/etc/sysconfig/powersave/common'.

Search for the definition of 'POWERSAVE_ACPI_MODULES' and add 'asus_acpi'.
Same goes for 'POWERSAVE_ACPI_MODULES_NOT_TO_UNLOAD'.

Set POWERSAVE_CPUFREQD_MODULE="p4-clockmod" (doesnt work well: cpu boot at 300Mhz instead of 2.400Mhz even I've set powersave as well! tryin to find help and further informations)

searching for other tips... stay tuned!

mozilla and firefox run better

Take Note: These tips are for SUSE 9.1 with the 2.6 kernel:

Mozilla and FireFox both seem to run a little slow on Suse 9.1 cause "ipv6". What is "ipv6"...sheee...I haven't a clue...but there is a fix...and after I applied it...both Mozilla 1.7 rc1 and FireFox opened and went to the different websites fast. Before the fix...both browsers would often just sit and spin their little icons...and never reach the sites before they timed out.

• Fix One: Go to >> /etc/modprobe.conf, right below this line:
  alias net-pf-10 ipv6
  add the following line:
  install ipv6 /bin/true
  Found this fix on Yahoo SCOX Message Board and credit for fix goes to w4rmc47, who posts on yahoo finance scox message board.

Canon i250

I found drivers for this cheap printer on this site :

http://203.111.45.57/bj/i250linux/ (CANON NEW ZELAND)

and downloaded the following:

• bjfiltercups-2.3-0.i386.rpm
• bjfilteri250-2.3-0.i386.rpm
• guidei250-2.3-0.tar.gz

install rpm with YaST as usual and unpack the last package cause this is the guide!
then, always in YaST, go to "hardware"(on left), "printer"(on right) and add your printer!

It WORKS WOW!!!!!

Apache, PHP, MySQL

this is the most difficult part...
I'll write the article when I'll finish all.

Gaim

First of all, if you installed the SuSE personal like me, you should change the source installation!

Do this :

1. open YaST
2. from left pannel choose "software" and from right choose "change installation source"
3. click "add" button and choose ftp or http and fill the form using a SuSE mirror
   
4. then disable the cd source and enable the source just added (dont enable more than one source or YaST will freeze when you will add packet choosin "install/uninstall packets")
   

Now we can install Gaim with his dependancies.
For installing using an rpm go to guru.linuxbe.org, download gaim and install it wit YaST!

EASY SuSE!! I love it.

Thunderbird

it was easy as installing firefox... I restored alse the folder wit my settings and email taken from windows wit just deletin

/-user-/home/.thunderbird/profiles

and

adding the profiles folder I had from windows ! easy and fantastic...

SuSE again UP and Running

I'm still curious about what happened to my SuSE and still angry about that!
Now I'm a little bit scared cause I think that if this happen when I'll have data on disk, I'll be lost! But let think over.... =D

I reinstalled also mozilla but, this time, I choosed the version without the installer and it worked on the first start... I HIGHLY reccomend it.
These are the operation I've done to install firefox via terminal:

download from site ( obvious! =D)
mkdir /opt/mozilla
mv /home/-user-/Desktop/firefox*.tar.gz /opt/mozilla/
ungzip firefox*.tar.gz
tar -xvf firefox*.tar
ln -s /opt/mozilla/firefox/firefox /home/-user-/Desktop/firefox

then you can apply the icon in kde!
thats all!
