[50] What is this 'tar' compression program?
tar is not a compression program. It just combines several files into one, without compressing them. tar file are often compressed with 'compress', resulting in a .tar.Z file. See question 2, file type .tar.Z. GNU tar has the capability to (de)compress files as well. When you have to archive a lot of very small files, it is often preferable to create a single .tar file and compress it, than to compress the individual files separately as in a zip archive. The compression program can thus take advantage of redundancy between separate files. The disadvantage is that you must uncompress the whole .tar file to extract any member. You can also improve compression by grouping files by type, as in: tar cvf - `ls | sort -t. +1` | gzip > file.tar.gz
