Tips and Tricks

WikiSysop:

== Paketverwaltung ==

=== Zu welchem Paket gehört Datei X ===
{{Codeline|# equery belongs -f <dateiname>}}

=== Welche Pakete haben USE-Flag X ===
{{Codeline|# equery hasuse <useflag>}}

=== Backup von installiertem Paket anlegen ===
{{Codeline|# quickpkg net-www/apache}}

Danach kann man das Paket auf einem anderen Rechner installieren oder schnell downgraden, wenn bei einem Update etwas schief gelaufen ist. Die Datei befindet sich dann in {{Filename|/usr/portage/packages/All}} bzw. ein Symlink auf die Datei in {{Filename|/usr/portage/packages/net-www}}. Zur Installation:

{{Codeline|# emerge --usepkgonly "<net-www/apache-2.2.4"}}

=== Überflüssige Pakete erkennen und entfernen ===
{{Codeline|# emerge depclean --pretend}}

=== Profil wechseln / auf neue Version updaten ===
{{Codeline|# emerge eselect}}

{{Codeline|# eselect profile list}}

{{Codeline|# eselect profile set <nummer>}}

== SCP Dateitransfer ==
Datenaustausch zwischen zwei Rechnern über Kommandozeile.

Datei hochladen:<br />
{{Codeline|# scp /root/htdocsbackup.tar.bz2 root@entfernter-server.de:/root/}}<br />
Datei runterladen:<br />
{{Codeline|# scp root@entfernter-server.de:/root/htdocsbackup.tar.bz2 /root/htdocsbackup.tar.bz2}}

== SSH Tunnel ==
Ist auf dem Server nur der SSH Port offen aber man möchte sich z.B. auf den auf Port 8080 laufenden Tomcat Webserver verbinden so kann man das über einen SSH Tunnel machen.

{{Codeline|# ssh -N -i /home/benutzer/.ssh/id_dsa -L 7777:webserver:8080 root@webserver}}

Anschließend kann man den Tomcat unter localhost:7777 erreichen.

== Yakuake DCOP-Skripte ==
=== MultiSSH ===
Per SSH auf mehrere Hosts verbinden, dafür jeweils ein neues Yakuake Tab anlegen und entsprechend benennen.
multissh.sh
<source lang="bash">
#!/bin/bash

[[ -n "$1" && -n "$2" ]] || {
echo "Usage: ./multissh.sh \"user\" \"server1 server2\""
echo " z.B.: ./multissh.sh \"root\" \"server1 server2\""; exit 0 ; }

lastid=`dcop yakuake DCOPInterface sessionIdList | awk -F, '{print $NF}'`

for i in $2 ; do
dcop yakuake DCOPInterface slotAddSession
let "lastid += 1"
dcop yakuake DCOPInterface slotRenameSession $lastid $i
dcop yakuake DCOPInterface slotRunCommandInSession $lastid "ssh $1@$i"
done

exit 0
</source>

=== MultiCommand ===
Ein Kommando in mehreren Yakuake Tabs ausführen.
multicommand.sh
<source lang="bash">
#!/bin/bash

[[ -n "$1" && -n "$2" ]] || {
echo "Usage: ./multicommand.sh \"tabname1 tabname2\" \"kommando\""
echo " z.B.: ./multicommand.sh \"server1 server2\" \"emerge --sync\""; exit 0 ; }

ids=`dcop yakuake DCOPInterface sessionIdList | sed 's/,/ /g'`

for i in $ids ; do
sessionname=`dcop yakuake DCOPInterface slotSessionName $i`

for x in $* ; do
if [ "$sessionname" = "$x" ] ; then
dcop yakuake DCOPInterface slotRunCommandInSession $i "$2"
fi
done
done

exit 0
</source>

== KDE4 Fixes ==
=== .gtkrc isn't honoured by GTK Applications anymore ===
KDE overrides the GTK colours with global ones, if you want that. If not (since it also overrides the GTK theme with the ugly default one) you can disable that behaviour under System Settings -> Appearance -> Colors at the bottom. This does not always work, so copy over your .gtkrc-2.0 from your homedir or one of the themes that come with the theme pack.

{{Codeline|# cp ~/.gtkrc-2.0 ~/.kde/share/config/gtkrc-2.0}}

{{Codeline|# cp /usr/share/themes/Clearlooks/gtk-2.0/gtkrc ~/.gtkrc-2.0}}

For more information have a look at [[GTK_Anwendungen_unter_KDE|GTK Applications under KDE]].

=== I accidently closed my taskbar, so what? ===
Reset to default by logging out and deleting from tty.

{{Codeline|# rm ~/.kde/share/config/plasma*}}

=== Change the Dolphin standard view to detailed view for ALL folders ===
Open Dolphin -> Settings > Configure Dolphin -> Views -> Common Tab -> and mark -> Use the same view for all folders

=== I can't configure any IM accounts in Kopete ===
Copy over your old files from kde3.
<pre>
Files:
.kde3.5/share/config/kopeterc
Complete directories:
.kde/share/apps/kopete
.kde/share/apps/kopete_history
.kde/share/apps/kopete_otr
.kde/share/apps/kopeterichtexteditpart
