Download recursive directories with wget using Username & Password for FTP

Apr 26th

Using ftp to download multiple files using ‘mget’ command is pretty common, however it downloads files from current directory only. But if you need to download recursive directories with all its content then? And specially when you don’t have shell access to the remote machine and you don’t have access to archive the targeted folder?

In such situation you can use ‘wget’ to download all recursive directories by providing your ftp details. For example:


wget -rc --user='ftpusername' --password='ftppassword' ftp://domain.com/directory_path/

Displaying information about your git repository

Want to see information about your git repository?

Based on a discussion here Duane Johnson wrote a very useful bash script. I am using this script from months and would like to share with you. You can download this script here(git-info.txt (483)).

You can also add an alias like below, so that I can be a accessed by a single command “gitinfo”

alias gitinfo="/home/akhil/git-info.txt"

When you run this script from your working copy it displays:

  • Remote URL
  • Remote Branches
  • Local Branches
  • Configuration (.git/config)
  • Most Recent Commit

Isn’t it useful, give it a try ;-)

Printing large image diagrams generated by RailRoad

Mar 23rd

I use RailRoad for generating Ruby on Rails diagrams, but always wish I could print those diagrams. Generally diagrams are too big to print on a single A4 size paper and I didn’t find any tool to print larger images in parts so that I can join them. If I print the image generated by RailRoad on single page, it of no use as it is hardly readable.

Fortunately, two days ago I found something which resolved this issue. It is a linux command and print a particular image on four pages. Here is that command:

lp -o scaling=200 models.png

Want to install rails stack on a machine? Just follow these steps. It will setup a rails stack(Apache + passenger + mysql + ruby + rubygems + common gems + git) on any server(debian based)

  1. apt-get update
  2. apt-get upgrade -y
  3. apt-get -y install build-essential libssl-dev libreadline5-dev zlib1g-dev
  4. apt-get -y install mysql-server libmysqlclient15-dev mysql-client
  5. apt-get -y install ruby ruby1.8-dev irb ri rdoc libopenssl-ruby1.8
  6. install rubygems manually:
    1. download rubygems form rubyforge, >=1.3
    2. unzip files
    3. ruby setup.rb
    4. Check that gem command is in path. Sometimes ‘gem1.8′ is available but ‘gem’ not. In that case copy /usr/bin/gem1.8 to /usr/bin/gem using “cp /usr/bin/gem1.8 /usr/bin/gem”
  7. apt-get -y install libmagick9-dev
  8. apt-get -y install imagemagick
  9. apt-get -y install postfix mailx
  10. apt-get -y install apache2
  11. apt-get -y install apache2-prefork-dev
  12. wget http://webonrails.com/wp-content/plugins/download-monitor/download.php?id=7
  13. ruby install_gems.txt
  14. passenger-install-apache2-module
  15. Download git from git-scm.com

    1. Unzip files
    2. ./configure –without-tcltk
    3. make -j 2
    4. make install

You are all set now, go deploy you rails app. I have tested it on linode(ubuntu8.10), slicehost(ubuntu 8.10), should work for you too
