cheat sheet - set pwd & setup xdebug

by Ray Sun — on  ,  , 

1. Send pwd to ‘sudo’ in shell script

The -S (stdin) option causes sudo to read the password from the standard input instead of the terminal device. The password must be followed by a newline character.

 echo "asdf" | sudo -S chmod 755 -R "${WEB_ROOT}/${INSTANCE_NAME}"

2. setup xdebug for ubuntu

automatically setting

sudo apt-get install php5-xdebug
ls /etc/php5/mods-available/
sudo php5enmod xdebug

manually setting

sudo apt-get install php5-xdebug
etc/php5/apache2/php.ini 
#add zend_extension="/usr/lib/php5/20121212/xdebug.so
#notice: the path may vary in different versions

3. modify host

ohray@ohraymaster-XXXXX:~/DataHouse/shellUtils$ cat /etc/hosts
127.0.0.1	localhost
127.0.0.1	ohraymaster-XXXXX

# The following lines are desirable for IPv6 capable hosts
::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

ohray@ohraymaster-XXXXX:~/DataHouse/shellUtils$ cat /etc/hostname 
ohraymaster-XXXXX
