When pack command is used the original file size is reduced by?
There is no "pack" command in Linux. However, there are numerous compression and archival programs available for use."tar" is an archival program. It does no compression, but allows you to put multiple files into one."gzip" is a compression program. However, it can only compress one file. Used in conjunction with tar, it is just slightly better than the ".zip" format."bzip2" is another compression program with better compression ratios. Like "gzip," it is for compressing single files only. It is usually used in conjunction with "tar.""zip" and "unzip" are programs for the "ZIP" archive format. It performs both compression and archival.Answer:I'm not sure if this is an improvement to the above answer or not. As mentioned above, there is no "pack" command in Linux but, in addition to the excellent answer above, a compiled program may be 'stripped' in Linux with the 'strip' command and this will usually serve to reduce the binary file size. The Linux 'strip' command modifies the binary program's symbol tables.
