If you want to create a tar that contains only files specified in a file you can use the -T option.
[[email protected] play]$ cat list.txt 1.txt 2.txt 3.txt [[email protected] play]$ tar -cvzf files.tgz -T list.txt 1.txt 2.txt 3.txt [[email protected] play]$ tar -tvzf files.tgz -rw-rw-r-- bcane/bcane 0 2011-07-13 16:48 1.txt -rw-rw-r-- bcane/bcane 0 2011-07-13 16:48 2.txt -rw-rw-r-- bcane/bcane 0 2011-07-13 16:48 3.txt
-T will work for both creation and extraction of tar files.
