Removing conf vars from site.conf.php (or whatever)

remove_conf_vars.sh

# Only works for vars that are expressed on one line, grep -A1 or a multilne pcregrep
# might be useful if you have longer var definitions.

# Check extant definitions
egrep "[$]conf\['related_videos_return'\]" --include site.conf.php .
# Blast em (note bsd/osx sed syntax, the first "" is not needed on gnu grep)
find . -type f -name site.conf.php -exec sed -i "" "/[$]conf\['related_videos_return'\]/d"  {} \;
# Check them again, they are gone!
egrep "[$]conf\['related_videos_return'\]" --include site.conf.php .


# Code to actually run
