如果是想限制某进程的 core 文件大小，请使用命令 prlimit --core=$size -p $pid

[root@test ~]# prlimit -c -p 17823
RESOURCE DESCRIPTION        SOFT      HARD UNITS
CORE     max core file size    0 unlimited blocks
[root@test ~]# 
[root@test ~]# prlimit -c=1 -p 17823
prlimit: failed to parse CORE limit
[root@test ~]# 
[root@test ~]# prlimit --core=1024 -p 17823
[root@test ~]# prlimit -c -p 17823
RESOURCE DESCRIPTION        SOFT HARD UNITS
CORE     max core file size 1024 1024 blocks
[root@test ~]#
