deleting /bin entries in linux
I have install centos. I want to remove bzip2. so I enter this command in shell
yum remove bzip2 bzip2-libs

Then near 500 packages was removed and I can't enter any command. for example
  

    ls 
    -bash: /bin/ls no such file or directory

how can I install the lost packages???
