pstack 327079|grep clssnm|awk '!a[$4]++ {print}'

某列求和
grep 192.168 jk.csv|awk -F , '{sum += $6} END {print (sum/1024)-360}'

chfs -a size=+10G /data

# /sbin/udevadm control --reload-rules
# /sbin/udevadm trigger --type=devices --action=change

修改ip
nmcli connection modify ens33 ipv4.method manual ipv4.addresses "192.168.204.200/24"
设置时区
timedatectl set-timezone Asia/Shanghai
查找删除文件
