Pour capturer les données sur le réseau
tcpdump -X -n -t -s 0 src 192.168.0.45
Pour afficher une image en arrière-plan (X-Windows)
wmsetbg --center --workspace 0 image.jpeg
Sylpheed
opera -newpage %s
Configuration du serveur LDAP
LDAP search string:
(&(mail=*)(cn=*%s*))
Configuration du client Email dans Opera
sylpheed --compose [mailto:%t][?subject=%s]
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
set LC_COLLATE=C
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
If you copy your timezone to /etc/localtime instead of making the normal symbolic link, all of /usr/share/zoneinfo can be removed.
If you don't use NLS, you can remove all the locale info in /usr/share/locale and /usr/lib/locale.
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"
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.
