.bashrc에 다음 줄을 작성했습니다. 각 명령 후에 모든 세션을 파일로 저장하십시오. 터미널을 시작한 것만 큼 많은 히스토리 파일이 있습니다. 가장 최근의 히스토리 파일에서 시작하여 새 터미널을 시작할 때 라인 카운트 임계 값에 도달 할 때까지 이전 세션의 모든 히스토리 파일을 히스토리 버퍼로로드하십시오.

# if HISTFILE unset, history is not saved on exit -> not really necessary if we save after each command, but its a double net safety
HISTSIZE=-1 # maximum number of commands to hold inside bash history buffer
HISTFILESIZE=-1 # maximum number of lines in history file
# history -a $HISTFILE # bash saves the total history commands entered since startup or since the last save and saves that amount of commands to the file. This means reading a history file after typing commands will trip up bash, but this won't be a problem if the history file is only loaded in the beginning. This means that only new commands are saved not all the old loaded commands, thereby we can load as many history files into the buffer as we want and still only save newly thereafter typed commands
