+====== Linux Snippets ======
+===== Disable firewall logging to console =====
+Edit ''/etc/init.d/klogd'' and set
+<file>
+KLOGD="-c 4"
+</file>
+===== mysqldump Options =====
+  #> mysqldump -u user -p --complete-insert --add-drop-table --databases db1 db2
+other options
+<code>
+--no-data
+--no-create-info
+--no-create-db
+</code>
+===== Export local webserver to public server =====
+  ssh andi@gaz.splitbrain.org -R *:8888:localhost:80
+===== Show humanreadable date from timestamp =====
+  $> perl -e 'print scalar(localtime(1098189697))."\n";'
+===== Swapfile =====
+Sometimes you need some swap space. Here is how to add some to a running system:
+  # dd if=/dev/zero of=/extraswap bs=1M count=512
+  # mkswap /extraswap
+  # swapon /extraswap
+===== Fedora yum Setup =====
+Import GPG keys for installing via yum
+  rpm --import /usr/share/rhn/RPM-GPG-KEY-fedora
+===== UTF-8 Terminal on an latin1 system =====
+Sometimes you need a terminal which can display UTF-8 but your system still uses latin1. Here is what I did:
+Install a unicode aware teminal emulator:
+  #> apt-get install rxvt-unicode
+Make sure you have a UTF-8 locale available eg. ''en_US.utf-8'' (check with ''locale -a''), use ''dpkg --reconfigure locales'' to build one if needed.
+Add this to your ''~/.bashrc''
+<file>
+  alias uterm='LANG=en_US.utf8 urxvt'
+</file>
+Now run ''uterm'' whenever you need the UTF-8 terminal.
+===== Find string in various files =====
+<code>
+find . | xargs grep 'string'
+</code>
+Or if you don't need the flexibility of find:
+<code>
+grep -R "string" *
+</code>
+(-R for recursive; the star as a file matching pattern)
