linux程序被killed

参考：https://blog.****.net/shuihupo/article/details/80905641

再次执行：xz -v -c -d < ontime.csv.xz | clickhouse-client –query=”INSERT INTO test.ontime FORMAT CSV”

同时再打开一个页面 我的天内存占满了

e6cfd8b39bd6c6503a5486e9d7ff23ccca72b1876a7ccdb6e3fb2f8e6a927476

仅输入PASSWORD=$(base64 < /dev/urandom | head -c8); echo "$PASSWORD"; echo -n "$PASSWORD" | sha256sum | tr -d '-'

生成
