Ubuntu检测磁盘是否挂载

Ubuntu默认不自动挂载磁盘.
只是学习Bash使用，需优化如使用

# file: mountAll.sh
# include color support
# a list of variables containing color code in xterm256
. bash.colors

# check if 
function isMounted {
  disk=$1
  for d in `mount -l | awk '{print $1}' | sort |uniq`;do
    if test "x$disk" = "x$d" ;then
    # use `=' for string comparison, and `-eq' for numbers in SHELL
    # in Perl5, string comparison is `eq' while numeric comparison is `='
    # I prefer the Perl way
      echo 1
      # mounted
      return
    fi
    # Note
    # the `commands` capture data from stand out or function return value
  done
  echo 0
  # not mounted
  return
}

function isAllMounted(){
  # check if there is disk not mounted
  for disk in '/dev/sdb1' '/dev/sdc1' '/dev/sdc2';do
    if test `isMounted $disk` -eq 0;then
    # 0 not mounted, 1 mounted
      echo 0
      return
    fi
  done
  echo 1
  # 1 all mounted, 0 at least 1 disk not mounted
  return
}

      else

      fi

      echo -e "${blue}Disks prepared$endc"

  esac
fi

如果没挂载要输入密码，可以把密码embeded到expect脚本中

# file mountSilent
#!/usr/bin/expect
spawn bash mountAll.sh
expect "password\r"
send "********"
interact
