linux環境下,清空history中記錄的歷史命令

需求描述:

　　今天在數據庫主機上操做,經過history看到有剛操做過的歷史記錄,想把這個清除了,

　　可是,還不影響後續的命令記錄,因此查了下,在此記錄.

操做過程:

1.經過history -c命令,完成清除歷史執行過的命令.

執行結果:

  794  2018-05-13 00:46:26 >kill -9 $(ps -ef | grep LOCAL=NO | grep -v grep | awk '{print $2}')
  795  2018-05-13 00:46:30 >ps -ef | grep LOCAL=NO
