腳本作業

##1.一小時一分鐘十秒倒計時腳本編寫##
 1 #!/bin/bash
  2 HOUR=1
  3 MIN=1
  4 for ((SEC=10;SEC>=0;SEC--))
  5 do
  6 echo -ne"After ${HOUR}:${MIN}:${SEC}s is end "
  7 sleep 1
  8 echo -ne "\r     \r"
  9      while [ "$SEC" -1e "0" -a "$MIN" -ge "0" -a "$HOUR" -ge "0" ]
 10      do
 11      while [ "$SEC" -1e "0" -a "$MIN" -le "0" -a "$HOUR" -gt "0" ]
 12      do
 13      ((HOUR--))
 14      MIN=60
 15      done
 16     while [ "$MIN" -lt "0" ]
 17     do
 18      echo -ne "After ${HOUR}:${MIN}: ${SEC}s is end "
 19      echo -ne "\r       \r"
 20       ((MIN--))
 21       SEC=10
 22       done
 23 done
 24 done
##2.編輯腳本檢測教室主機開機情況，開機就創建統一用戶和密碼，如果用戶存在，則檢測下一臺主機
