## rvm cron setup
You need to setup your crontab with rvm e.g:

rvm cron setup

With that rvm sets your environment variables in your crontab file

then you have a crontab file having this at the top:

PATH="/usr/local/rvm/gems/ruby-1.9.3-p194/bin:/usr/local/rvm/gems/ruby-1.9.3-p194@global/bin:/usr/local/rvm/rubies/ruby-1.9.3-p194/bin:/usr/local/rvm/bin:/usr/local/rvm/gems/ruby-1.9.3-p194/bin:/usr/local/rvm/gems/ruby-1.9.3-p194@global/bin:/usr/local/rvm/rubies/ruby-1.9.3-p194/bin:/usr/local/rvm/bin:/usr/lib64/qt-3.3/bin:/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/sbin:/usr/local/rvm/gems/ruby-1.9.3-p194@global/"
rvm_env_string='ruby-1.9.3-p194'

    visit('/projects')

=Clicking links and buttons=
    click_link('id-of-link')
    click_link('Link Text')
    click_button('Save')
    click('Link Text') # Click either a link or a button

## Show views in MySQL
SHOW FULL TABLES IN database_name WHERE TABLE_TYPE LIKE 'VIEW';

## Directory size and disk space.sh
du -sh * #directory size in human format
df -h #disk space in human format

## variables2.sql
set @checked=(select GROUP_CONCAT(id) from table_name where atribute_name=1);

UPDATE table_name
set atribute_name=0
where FIND_IN_SET(id,@checked)>0;

## focus to the first text input or textarea.js
$(document).ready(function() {
    var first_input = $('input[type=text]:visible:enabled:first, textarea:visible:enabled:first')[0];
    if(first_input != undefined){ first_input.focus(); }
});
