--xz and -J are equivalent. --bzip2 and -j are equivalent There are three types of options: long, short, and old. long: starts with two dashes short: starts with one dash old: no dashes and deprecated "Some options _may_ take an argument. Such options may have at most long and short forms, they do not have old style equivalent." Old style options are also position dependent on the command line while the others are not. It doesn't make sense to mix short and old arguments. Use 'tar -xf filename' in lfs to prevent confusion. -- Bruce -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page
