MYSQL drop all tables in database in linux

Taken from http://knaddison.com/technology/mysql-drop-all-tables-database-using-single-command-line-command#comment-3588.

#!/bin/sh

mysql --user=$1 --password=$2 -BNe "show tables" $3 | tr 'n' ',' | sed -e 's/,$//' | awk '{print "SET FOREIGN_KEY_CHECKS = 0;DROP TABLE IF EXISTS " $1 ";SET FOREIGN_KEY_CHECKS = 1;"}' | mysql --user=$1 --password=$2 $3

Save code above in a file, say, mysql-drop-tables. Then change the permission to excecuteable

chmod +x mysql-delete-tables

Then run it

mysql-drop-tables dbuser dbpassword dbname

Installing PIL in virtualenv in Ubuntu

To install PIL in virtualenv in ubuntu, these are the steps:

1. install the dependencies needed to build PIL

   sudo apt-get build-dep python-imaging

2. then run these commands

   sudo ln -s /usr/lib/i386-linux-gnu/libfreetype.so /usr/lib/
   sudo ln -s /usr/lib/i386-linux-gnu/libz.so /usr/lib/
   sudo ln -s /usr/lib/i386-linux-gnu/libjpeg.so /usr/lib/

   If you’re using 64bit system, switch i386-linux-gnu to x86_64-linux-gnu.

   If you don’t do it, you might see these messages when after building PIL, and you won’t have jpeg support.

   *** JPEG support not available
   *** ZLIB (PNG/ZIP) support not available
   *** FREETYPE2 support not available

3. Last command, install PIL

   pip install PIL
