How to make git-diff ignore specific lines

Recently I use git for versioning Cisco router/switch configurations. One problem here is the ‘ntp clock-period’ line.

Before loading ‘wp-load.php’, you have to set PHP ‘$_SERVER’ variable. Especially in a multisite environment, WordPress will determine which site to involve by $_SERVER values. #!/usr/bin/php <?php // define(‘WP_DEBUG’, true); /* uncomment for debug */ $_SERVER = array( "HTTP_HOST" … Continue reading WordPress in command line scripts
