FYI, I have in my .zshrc:

unarch()
{
  local file decomp
  for file in $@
  do
    unset decomp
    [[ ( $file:e == gz && $file:r:e == tar ) || $file:e == tgz ]] \
      && decomp=gunzip
    [[ $file:e == bz2 && $file:r:e == tar ]] \
      && decomp=bunzip2
    [[ $file:e == lzma && $file:r:e == tar ]] \
      && decomp=unlzma
    if [[ -z $decomp ]] then
      echo "Usage: $0 [ \033[4mtgz-file\033[m | \033[4mbz2-file\033[m ] | \033[4mlzma-file\033[m ] ..." >&2
      return 1
    fi
    if [[ -r $file ]] then
      echo "$0 $file ..."
      $decomp $file -c | tar xf -
    else
      echo "$0: $file is not readable" >&2
    fi
  done
}
