Any ideas what the problem might be opening a .gz file on linux? Gunzip goes through the motions and overwrites the 2012-June.txt.gz file, creating file: 2012-June.txt. When a text editor attempts to open this file, the file appears to have codes that prevent it from being interpretted correctly. I am able to successfully create a new text file, compress it with gzip to create a .gz file, then gunzip it to decompress it, and open it with a text editor. Something is different between the text files I create and the archived Racket text files. I suspected that the problem might be that the Racket text files had end of line characters appropriate for Windows, not Linux, however I tried opening the file with OpenOffice.org Word Processor, with different each of the end of line options in turn. Each time the file appears to have some non-ascii characters. Thanks.
