I tried opening a file in ruby with the following code but I got this unknown error message.
No such file or directory - -p
Code:
myfile=File.open("/home/cucumber/profiles/data.csv","r")
Please advice with the correct method to do.
Ensure whether file exists in the designated location or not, either you check it manually or use in code:
File.exists?("/home/cucumber/profiles/data.csv")

I have a string like this /4/LM2301_800.mp4.
I would like to use a regex to strip the /4/ and the _800 from the file name.
I am currently trying to use the strip command. Can anyone point me in the right direction?
Your file could be deeply nested inside a directory structure:
path = "/4/LM2301_800.mp4"
path.sub(/^(\/.)*\/(.*)_\d+\.mp4/, $2)
=> "LM2301" # you already know these are mp4 files, so you could add the suffix
Or:
path = "/4/LM2301_800.mp4"
path.sub(/^(\/.)*\/(.*)_\d+\.(.*)/, $2+'.'+$3)
=> "LM2301.mp4"
" /4/LM2301_800.mp4".scan(/.*\/(.*?)_\d*(.*)/).join
=> "LM2301.mp4"

I want add all status in magento sales order Comment History Box. I have magento1.6.2.0.
I have try to changing in app/code/core/Mage/Sales/etc/config.xml file and add statuses but nothing was changed please help.
No need to change in the code go to Admin Panel->System->Order Statuses you could create states and assign them to whichever status you want them to be.
In magento States are the visible status of the order and Status is the internal status of the order. A bit confusing but if you take a look at the page you should be to get an idea of what this means.

I'm thinking about duplicating the system\english\form_validation_lang.php file or folder, but I don't know how could I work that out.
For new languages, you should just create a new form_validation_lang.php file inside each language folder, like:
application/language/portugues/form_validation_lang.php
application/language/espanol/form_validation_lang.php
application/language/french/form_validation_lang.php
Then, you just have to set the appropriate language and Codeigniter will fetch the translations according to the language set.
More information can be found in the Codeigniter User Guide

I'm stuck here:
puts "#{percent_finished.round}% uploading complete" ? if/unless ...
If percent_finished is part of an ActiveRecord model, you can actually just make a call to percent_finished_changed?.
For example:
puts "#{percent_finished.round}% uploading complete" if percent_finished_changed?
Here's some documentation:
http://ar.rubyonrails.org/classes/ActiveRecord/Dirty.html
Is this a command line tool?
last_percent = nil
upload_loop do
# ...
percent_rounded = percent_finished.round
puts "#{percent_rounded}% uploading complete" if percent_rounded != last_percent
last_percent = percent_rounded
end
