these commands work on all other systems i have tested it on. None of them are
It seems that tail doesn't like +2 on fedora but works on Ubuntu, SuSE and all
other linux systems i try it on.
Thanks for report, but it's not a bug.
If Ubuntu, SUSE and other linux systems works, it does mean that they have VERY
old coreutils package(behaviour changed in 2005) or they made fork from upstream
in this case. Both is bad idea, as the current way how Fedora coreutils handles
this command conforms to the latest POSIX and upstream.
There is easy workaround to make tail working with "obsolete syntax" ... Simply add
alias tail="_POSIX2_VERSION=199209 tail"
to .bashrc (or to other file at system level which accepts aliases).
