Hi. My users use a lot of different compression programs. They cannot remember which tool to use to decompress and print to stdout for each of the programs.
For gzip it is zcat, for bzip2 it is bzcat, for 7z it is 7z x -so, for zip it is unzip -qc and so on. So I have made a small program called zzcat that will use file and lzmainfo to determine the filetype. Then it will call the right command to get the stuff on stdout. I hope you will include it in gzip. /Ole
