amosshapira / rename graphite metrix after upgrade to 5.2.1

Last active December 17, 2015 15:29

Have you upgraded collectd from pre-5.2.1 to 5.2.1 or higher (5.3 in my case) and it started to send graphite metrics without the annoying ".value" in the name? Here is a quick find command to rename the old files to the new names.

find -name value.wsp -printf "mv -v %h.wsp %h.wsp.new; mv -v %p %h.wsp\n" | /bin/sh

amosshapira / find-puppet-resource-failutes.rb

Last active December 20, 2015 07:58

This script takes a list of names of Puppet report files and extract the names and time stamps of failed resources.

	#!/usr/bin/env ruby

	require 'yaml'

	ARGV.each do \|filename\|
	yaml = YAML.load_file(filename)
	hash = yaml.ivars["resource_statuses"]
	# The following line will just print the resource reference
	# puts hash.keys.sort.select{\|resource\| hash[resource].ivars["failed"]}
	# The following line will also print the resource time stamp, it demonstrates access

Common problem - root file system (or another file system which has other file systems mounted under it) is full and you want to run "du" only on directories which are only on the current file system in order to find the break down of the space users:

	#!/bin/bash
	find -mindepth 1 -type d -prune \|
	while read i
	do
	[[ $(stat -c %m $i) == $(stat -c %m $(pwd)) ]] && echo $i
	done \|
	xargs du -shcx \|
	sort -h

amosshapira / html to csv in ruby

Last active December 28, 2015 13:59

Convert HTML from input files (or standard input, if no file name given) to CSV. Taken from a stackoverflow.com answer I lost since.

	#!/usr/bin/ruby
	require 'nokogiri'

	doc = Nokogiri::HTML(ARGF.read)

	doc.xpath('//table//tr').each do \|row\|
	row.xpath('td').each do \|cell\|
	print '"', cell.text.gsub("\n", ' ').gsub('"', '\"').gsub(/(\s){2,}/m, '\1'), "\", "
	end
	print "\n"

amosshapira / replace-plus-with-urlconde

Last active August 29, 2015 13:56

Replace all "+" characters in file names to "%2b" url encoded

	What I like about this way of doing this is that it takes advantage of Bash internals without external commands.

	for i in *; do mv $i ${i//+/%2b}; done
