==Installation instructions for scanner EPSON Perfection V100 Photo==
 
 
The scanner can be controlled either by iscan or by xsane, but in both cases
 
the firmware files, the iscan plugin library, iscan-data, iscan and the
 
sane configuration files (dll.conf and epkowa.conf) must be installed.
 
 
Note 1: The usbfs (/proc/bus/usb) filesystem is not necessary even if using
 
libusb.
 
 
Note 2: It seems that the iscan-registry command must be executed even if
 
using sane.
 
 
Note 3: The epkowa back-end comes from iscan (not from sane).
 
 
1. Download:
 
iscan-plugin-gt-s600-2.0.0-1.c2.i386.rpm
 
or
 
iscan-plugin-gt-s600-2.1.2-1.x86_64.rpm
 
 
2. Extract content of RPM:
 
rpm2cpio iscan-plugin-gt-s600-...rpm > iscan-plugin.cpio
 
 
3. Extract files from CPIO archive:
 
mkdir iscan-plugin
 
cd iscan-plugin
 
cpio -ivd < ../iscan-plugin.cpio
 
 
4. Copy firmware files and plugin:
 
cp -a usr/share/iscan /usr/share
 
cp -a usr/lib/iscan /usr/lib
 
 
5. Download and install " iscan-data_1.9.0-1.tar.gz"
 
./configure --prefix=/usr &&
 
make &&
 
make install
 
 
6. Download and install "iscan_2.26.4-2.tar.gz"
 
./configure --prefix=/usr --localstatedir=/var &&
 
make &&
 
make install
 
 
8. Create entry for scanner:
 
iscan-registry --add interpreter usb 0x04b8 0x012d \
 
/usr/lib/iscan/libesint66 \
 
/usr/share/iscan/esfw66.bin
 
 
This will create the file /var/lib/iscan/interpreter.
 
 
9. In "/etc/sane.d/dll.conf":
 
epkowa
 
 
10. Create file "/etc/sane.d/epkowa.conf":
 
usb
 
 
Note: when I put this line in epkowa.conf:
 
usb 0x04b8 0x012d
 
it took 2 minutes for iscan to show the scan window!
 
 
11. Activate either xsane or iscan plugin (or both) for Gimp:
 
ln -s /usr/bin/xsane /usr/lib/gimp/2.0/plug-ins
 
ln -s /usr/bin/iscan /usr/lib/gimp/2.0/plug-ins
 
 
Example to launch xsane abd display some traces:
 
SANE_DEBUG_EPKOWA=CMD xsane
 
 
Example to specify the device directly:
 
SANE_DEBUG_EPKOWA=CMD xsane epkowa:interpreter

Setup French Canadian (old ca_enhanced) layout

With Xorg7, "ca_enhanced" is no more. You have to do a little trick to get the same layout that you are used to: Switch the old:

      Option          "XkbLayout"     "ca_enhanced"

To:

      Option          "XkbLayout"     "ca"
      Option          "XkbVariant"    "fr"

Démarrage Linux sans authentification

Dans le fichier /etc/inittab, remplacer cette ligne:

 1:12345:respawn:/sbin/agetty 38400 tty1

par celle-ci:

 1:12345:respawn:/sbin/agetty -n -l /bin/bootdisk-login 38400 tty1

et créez le script /bin/bootdisk-login:

 #! /bin/sh
 export HOME=/root
 export PS1='\u:\w\$ '
 export PATH=/bin:/usr/bin:/sbin:/usr/sbin
 cd ${HOME}
 /bin/bash --login
 exit $?

Si vous voulez démarrer X sans authentification pour un usager en particulier, voici le script à utiliser:

 #! /bin/sh
 su <usager> -c /usr/X11R6/bin/startx
 exit $?

Affichage des fichiers avec majuscule en premier

How to do a search and replace over multiple files?

You could use find and sed, but I find that this little line of perl works nicely:

   perl -pi -w -e 's/search/replace/g;' *.php 
 -e means execute the following line of code.
 -i means edit in-place
 -w write warnings
 -p loop

Example I had the following style sheet in a section:

 <link rel="stylesheet" type="text/css" href="../includes/style.css">

and I wanted the following instead:

 <link rel="stylesheet" type="text/css" href="admin.css">

As each expression is a regular expression you've got to escape the special characters such as forward slash and .

 \.\.\/includes\/style\.css

So the final line of code ends up as

 perl -pi -w -e 's/\.\.\/includes\/style\.css/admin\.css/g;' *.php

Installation de style file latex

Éxécuter la commande:

 mktexlsr

après avoir installé le fichier .sty

Supprimer un "/" à la fin

DIR="/usr/local/bin/"
echo ${DIR%/}

Effacer plusieurs fichiers avec find

find . -name .svn -exec rm -rf {} \;

LFS: Comment sauver de l'espace disque

/usr/share/zoneinfo

If you copy your timezone to /etc/localtime instead of making the normal symbolic link, all of /usr/share/zoneinfo can be removed.

/usr/share/locale and /usr/lib/locale

If you don't use NLS, you can remove all the locale info in /usr/share/locale and /usr/lib/locale.

/usr/share/man

Les répertoires /usr/share/man{cs,de,es,fi,fr,sauver de l'espace disquehu,id,it,ja,ko} etc peuvent être enlevés.

Comment synchroniser deux répertoires

Le répertoire dest va devenir un miroir de src:

 $> rsync -av --delete src/* dest

Installation CUPS-PDF

 Sur le serveur (web admin interface, port 631), cliquer sur "Find New Printer"
 Sélectionner "Generic Make"

 Model: Sélectionner "Generic CUPS-PDF Printer (en)"

tar avec SSH

 tar jcvf - directory | ssh user@host "cat > directory.tar.bz2"

Navigateur par défaut pour les applications Gnome

Éxécuter:

 $> gnome-default-applications-properties


Syntax highlighting MediaWiki

Replace in skins/monobook/main.css:

pre {
	padding: 1em;
	border: 1px dashed #2f6fab;
	color: black;
	background-color: #f9f9f9;
	line-height: 1.1em;

With:

pre {
	padding: 1em !important;
	border: 1px dashed #2f6fab !important;
	color: black;
	background-color: #f9f9f9 !important;
	line-height: 1.1em !important;

Lecture température disque dur

 $> hddtemp /dev/sda

SMART Disk Monitoring Daemon

 $> apt-get install smartmontools
 $> smartctl -t long /dev/sda [wait until test completes, then]
 $> smartctl -l selftest /dev/sda

Changement du mot de passe usager

Si vous avez ce message d'erreur:

 password for ' null ' gnome keyring

Il faut éxécuter:

 $> rm ~/.gnome2/keyrings/login.keyring

Combiner plusieurs documents PDF en un seul

 $> gs -dBATCH -dNOPAUSE -q -sDEVICE=pdfwrite -sOutputFile=finished.pdf file1.pdf file2.pdf

Si les sources sont des images, on peut utiliser ImageMagick:

 $> convert *.gif foo.pdf


Désactiver mode large files

si vous avez ce message quand vous essayez de monter un disque:

 EXT4-fs (sda1): Filesystem with huge files cannot be mounted read-write without CONFIG_LBDAF

Selon la doc du kernel de Linux:

The ext4 filesystem requires that this feature be enabled in
order to support filesystems that have the huge_file feature
enabled.  Otherwise, it will refuse to mount in the read-write
mode any filesystems that use the huge_file feature, which is
enabled by default by mke2fs.ext4.

The feature can be removed from an existing filesystem by running the following commands:

 $> tune2fs -O ^huge_file /dev/whatever
 $> fsck /dev/whatever

This should allow you to mount the drive without CONFIG_LBDAF in the kernel.


RTC

Pour que Linux ajuste automatiquement son horloge selon le RTC au démarrage, il faut:

 Ne pas sélectionner "Enhanced Real-time clock Support" dans "Device Drivers  ---> Character devices  --->"
 Sélectionner (built-in ,pas modulaire) "Device Drivers  ---> Real Time Clock  ---> Set system time from RTC on startup and resume"

Avec ça, plus besoin du script /etc/rc.d/init.d/setclock
