+ | |||
+ | ===== Disable firewall logging to console ===== | ||
+ | |||
+ | Edit ''/ | ||
+ | |||
+ | < | ||
+ | KLOGD=" | ||
+ | </ | ||
+ | |||

+ | ===== mysqldump Options ===== | ||
+ | |||
+ | #> mysqldump -u user -p --complete-insert --add-drop-table --databases db1 db2 | ||
+ | |||
+ | other options | ||
+ | |||
+ | < | ||
+ | --no-data | ||
+ | --no-create-info | ||
+ | --no-create-db | ||
+ | </ | ||
+ | |||
+ | ===== Export local webserver to public server ===== | ||
+ | |||
+ | ssh andi@gaz.splitbrain.org -R *: | ||
+ | ===== Show humanreadable date from timestamp ===== | ||
+ | |||
+ | $> perl -e 'print scalar(localtime(1098189697))." | ||
+ | |||
+ | ===== Swapfile ===== | ||
+ | |||
+ | Sometimes you need some swap space. Here is how to add some to a running system: | ||
+ | |||
+ | # dd if=/ | ||
+ | # mkswap /extraswap | ||
+ | # swapon /extraswap | ||
+ | |||
+ | ===== Fedora yum Setup ===== | ||
+ | |||
+ | Import GPG keys for installing via yum | ||
+ | |||
+ | rpm --import / | ||
+ | |||
+ | ===== 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. '' | ||
+ | |||
+ | Add this to your '' | ||
+ | |||
+ | < | ||
+ | alias uterm=' | ||
+ | </ | ||
+ | |||
+ | Now run '' | ||
+ | |||
+ | |||
+ | ===== Find string in various files ===== | ||
+ | < | ||
+ | find . | xargs grep ' | ||
+ | </ | ||
+ | |||
+ | Or if you don't need the flexibility of find: | ||
+ | |||
+ | < | ||
+ | grep -R " | ||
+ | </ | ||
+ | |||
+ | (-R for recursive; the star as a file matching pattern) |
