gzcat nethack-360-src.tgz > nethack-360-src.tar tar xf nethack-360-src.tarSome versions of Linux do not have a gzcat command. Use the following commands instead:
gzip -dc nethack-360-src.tgz > nethack-360-src.tar tar xf nethack-360-src.tar
The gzip package (containing gzip, gunzip, and gzcat) may be obtained from the Free Software Foundation. A version of tar is also available from the same site.
