How To Clear DNS Cache In Mac OS and Windows

Ever wanted to clear DNS cache on your mac os? I use it all the time … and over and over again I am searching for the same command line. To keep the records also for me here it is:

1
$ dscacheutil -flushcache

Here is the line for CMD on your Windows machine:

1
C:\>ipconfig /flushdns

Install PEAR and add path to $PATH on Mac

Recently I was just installing PEAR and I needed to add it to $PATH. I stumbled upon site of muttsnutts notes and here is the path I’ve been following to do it:

Here is how to install PEAR:

1

3
$ cd /Users/robertkuzma
$ wget http://pear.php.net/go-pear.phar
$ php -d detect_unicode=0 go-pear.phar

The syntax for adding $PATH:

1
sudo sh -c 'echo "/Users/robertkuzma/pear/bin" >> /etc/paths.d/pear_path'

Eventually for PEAR to work in PHP you will also need to add the include line to php.ini file.

1
include_path=".:/Users/robertkuzma/pear/share/pear"

And how to check if pear is actually working in your PHP? You have to include System.php class because it comes embeded with PEAR.

<?php

require_once 'System.php';
if(class_exists('System')===true) {
    echo 'PEAR is installed!';
} else {
    echo 'PEAR is not installed :(';
}

?>

or a bit more simple:

<?php

require_once 'System.php';
var_dump(class_exists('System', false));

?>
