Here's the command this article is talking about:

openssl x509 -in proxy.cer -inform der -outform pem -out proxy.crt

This command basically converts a binary certificate into a base64-encoded one (i.e. text).

One of the problems with working on Linux and Windows OSes has to do with manipulating text files. Lines are separated by a carriage return and a line break character in text files on Windows, whereas on Linux, the separation is done through a single line break character.

During the lifetime of using the computer, I believe everyone will inevitably face the scenario where you will want resize multiple images to a certain size.

In Linux, you can do it will such ease that makes you wonder what you use Windows for.

This effect can be easily done using the command line. Naysayers will probably disclaim the effectiveness of this tip but it really is easy for those who know Linux. All you have to do is to go into the directory where the images are stored and run the following command:

for k in $(ls *.jpg); do convert $k -resize 1024x768 -quality 100 re_$k; done

This Bash command does the job pretty well...
