I have an application where I want to get the RPM info of several packages and format it in a pleasing and eye-catching way. *boom*.
My problem is that rpm wants to format the data into two columns, which is annoying.
Command
rpm -qi ruby

Is there any way to get this formatting without manually specifying a reaally long --queryformat?
Alternatively, any way to do this native to Ruby would be fine.
pairs = %x{rpm -qi ruby}
.split(/(?<!:)\s{2,}(?![\s:])|#$//)
.map{|line| line.split(/\s*:\s+/, 2)}
width = pairs.map{|pair| pair.first.length}.max
pairs.each{|k, v| puts "#{k.ljust(width)}: #{v}"}

Can you help me with writing a bash script for switching wallpaper between day and night version under XFCE? I want to set a cron job for running it so it will switch automatically based on the time of the day.
I wrote a script:
#!/bin/bash
xfconf-query -c xfce4-desktop -p /backdrop/screen0/monitor0/workspace0/last-image -s /home/maciek/Pictures/day.jpg
It works when I run it from a terminal. But when I set it up in cron it doesn't work. I get an error:
Failed to init libxfconf: Using X11 for dbus-daemon autolaunch was disabled at compile time, set your DBUS_SESSION_BUS_ADDRESS instead.

I have been trying the following methods to Backup & Restore an ElasticSearch cluster from one server to another with little success. I have not used a backup process thus far and I would like to move my whole ElasticSearch cluster from a small 2GB cluster to 15GB cluster. I used the following methods.
Using taskrabit/elasticsearch-dump - I was successfully able to export the complete database to backup.json file, however when restoring the backup.json, it gave me the following output. After researching the output further I understood that the bulk input of the plug-in was not fully developed.
./bin/elasticdump --all=true --input=/home/user/backup.json --output=http://192.168.0.213:9200/ --type=data
Thu, 09 Feb 2017 06:43:29 GMT | starting dump
Thu, 09 Feb 2017 06:43:29 GMT | got 61 objects from source file (offset: 0)
Thu, 09 Feb 2017 06:43:29 GMT | sent 61 objects to destination elasticsearch, wrote 0

Thu, 09 Feb 2017 06:43:29 GMT | Total Writes: 0
Thu, 09 Feb 2017 06:43:29 GMT | dump complete
Using elasticsearch-tools (es-export-bulk & es-import bulk) I again was able to backup the json successfully. But the import failed once again with an error:
"statusCode":400,"response":"{"error":{
I used the examples from es-bulk-export
Using the ElasticSearch built-in Snapshot & Restore.
curl -XPUT 'http://localhost:9200/_snapshot/my_backup' -d '{
"type": "fs",
"settings": {"location": "/home/shawn/backup", "compress": true}
}'
I believe I'm missing something as the execution gives me the following error. Do I need to create /_snapshot/my_backup? If so how?
{"error":{"root_cause":[
{"type":"repository_exception",
"reason":"[my_backup] location [/home/shawn/backup] doesn't match any of the locations specified by path.repo because this setting is empty"
}],
"type":"repository_exception","reason":"[my_backup] failed to create repository",
"caused_by":

You are creating your _snapshot/my_backup just fine, You only need to add line to /etc/elasticsearch/elasticsearch.yml:
path.repo: ["/home/shawn/backup"]
Which is actual location of your snapshot. Then restart Elasticsearch.
I want to create a patch for a header in order to fix my appveyor build. I used WinMerge to create the following file:

#if defined(Q_OS_WIN)

// Note: Mac OSX is a "controlled platform" for OpenGL ABI so we
When running the patch command I get the following result:
C:\Users\Martin\dev\TravisTest>patch -u patch_qopengl c:\Qt\5.3\mingw482_32\include\QtGui\qopengl.h

What's wrong?
I am able to parse localized dates using python locale module and posix localization database:
import locale, datetime
locale.setlocale(locale.LC_TIME, 'tr_TR.UTF-8')
print datetime.datetime.strptime("1 Haziran 2014", "%d %B %Y")
===
Edit
This example loads the locale and datetime modules, parses the localized date to create an instance of python's datetime class. I'm looking specifically for Ruby code that can parse localized dates using posix database.
===
Is there any equivalent of this in ruby? If there is a ruby library like python's locale module or Boost.Locale in C++, can you give example code? I tried the gettext gem and locale gem (I set current locale and tried Time.strptime, which failed).
I do not expect to do custom gsub or an i18n config file parsing. I am asking for code that uses posix database to parse dates.
You will need 2 custom gems in your Gemfile
Chronic:
$ git clone git://github.com/mojombo/chronic.git
$ cd chronic && gem build chronic.gemspec
$ gem install chronic-*.gem
Chronic-l10n:
$ git clone git://github.com/luan/chronic-l10n.git
$ cd chronic-l10n && gem build chronic-l10n.gemspec
$ gem install chronic-l10n-*.gem
Usage:
require 'chronic'
require 'chronic-l10n'
Time.now #=> Sun Aug 27 23:18:25 PDT 2006
Chronic.locale = :'pt-BR'
Chronic.parse('amanhã')
#=> Mon Aug 28 12:00:00 PDT 2006
Chronic.parse('segunda', :context => :past)
#=> Mon Aug 21 12:00:00 PDT 2006
Chronic.parse('essa terça 5:00')
#=> Tue Aug 29 17:00:00 PDT 2006
Chronic.parse('essa terça 5:00', :ambiguous_time_range => :none)
#=> Tue Aug 29 05:00:00 PDT 2006
Chronic.parse('27 de maio', :now => Time.local(2000, 1, 1))
#=> Sat May 27 12:00:00 PDT 2000
Chronic.parse('27 de maio', :guess => false)
#=> Sun May 27 00:00:00 PDT 2007..Mon May 28 00:00:00 PDT 2007
Chronic.parse('6/4/2012', :endian_precedence => :little)
#=> Fri Apr 06 00:00:00 PDT 2012
It seems there is currently no ruby gem or code that can load posix database and parse dates using strptime style flags. (copy-paste answer is not accepted)
