title: how to change encoding of a text file without openning the file in shell programming
body: <p>there are about 28000 articles in our institution and their encoding is not utf-8. I was asked to find a way to change their encoding to utf-8. is there any linux or windows command that changes the encoding of file without opening the file? clearly it is not a good idea to open 28000 files and changing them one by one!</p>
