1. 复制命令 库等

   1. export command_list=("bash" "ls" "dpkg" "apt" "whoami" "whereis" "vim" "cat" "grep" "awk" "adduser" "groups" "perl" "su" "sudo" "passwd" "id" "mknod" "rm" "cp" "mv" "file" "mkdir"
      )
      create_file(){
          echo "create sys file"
          mkdir -p ./{root,dev,usr,etc,home}
      }
      
      copy_file(){
          mkdir -p .`dirname $1`
          #如果使用-r 那么如果文件时软连接的话 只会复制软链接 并不会复制真正的文件
          cp -u $1 .$1
      }
      copy_dir(){
          mkdir -p .`dirname $1`
          cp -ru $1 .$1
      }
      
      copy_command_lib(){
          # ldd $1 1>/dev/null 2>/dev/null || echo -n "static"
          #LIB为命的的库绝对路径
          LIB=`ldd $1 2>/dev/null| grep 'lib.*=>.*' | awk  '{print $3}'`
          for i in $LIB;do
              copy_file $i
          done
      }
      copy_command(){
          copy_file $1
      }
      
      copy_bash_conf(){
          echo "copy bash_conf ..."
          copy_file /etc/{profile,bash.bashrc}
          copy_file /etc/bash_completion
          copy_file /etc/passwd
          copy_file /usr/share/bash-completion/bash_completion
          copy_dir /etc/bash_completion.d
          
          
      }
      copy_system_conf(){
          echo "copy system_conf ..."
          copy_file /etc/hosts
          copy_file /home/fashion/.bashrc 
      }
      
      copy_common_lib(){
          copy_file /lib64/ld-linux-x86-64.so.2
      }
      
      create_file
      copy_common_lib
      copy_bash_conf
      copy_system_conf
      
      #循环复制数组中的命令 以及命令依赖的so
      for i in ${command_list[*]};do
          absulute_path=`whereis -b $i | awk '{ print $2}'`
          [[ $absulute_path == "" ]] && echo $i "command not found " && continue
          
          echo "copy" $absulute_path
      	copy_command $absulute_path
          copy_command_lib $absulute_path
      done
      cd ..
      cp ./initenv.sh ./chroot
      

      1. 只需要在command_list 数组中增加命令 即可往chroot环境中添加命令
