There is no need to use the ''eos'' commands anymore. The mounted file systems are:
   * eoscms --> ''/eos/cms/''   * eoscms --> ''/eos/cms/''
   * eoslhcb --> ''/eos/lhcb/''   * eoslhcb --> ''/eos/lhcb/''
   * eosuser --> ''/eos/user/''   * eosuser --> ''/eos/user/''
 +  * ...
 To access these file systems, you need to have a CERN Kerberos ticket as for the EOS commands, but in addition you need to pass the ticket to the fuse system with the command ''eosfusebind'', similar to the ''aklog'' command for AFS. You need therefore to execute the following commands:\\ ''kinit <cern_username>@CERN.CH ; eosfusebind'' To access these file systems, you need to have a CERN Kerberos ticket as for the EOS commands, but in addition you need to pass the ticket to the fuse system with the command ''eosfusebind'', similar to the ''aklog'' command for AFS.

 EOS commands and Linux commands in the EOS file system are not very resource efficient. If you need to transfer large amount of data, use the ''xrdcp'' command: EOS commands and Linux commands in the EOS file system are not very resource efficient.
