显示实际的“ulimit”消耗

显示实际的“ulimit”消耗

运行 ulimit -a 显示为当前用户/shell 设置的限制:

$ ulimit -a
core file size          (blocks, -c) 0
data seg size           (kbytes, -d) unlimited
scheduling priority             (-e) 0
file size               (blocks, -f) unlimited
pending signals                 (-i) 353732
max locked memory       (kbytes, -l) 64
max memory size         (kbytes, -m) unlimited
open files                      (-n) 1024
pipe size            (512 bytes, -p) 8
POSIX message queues     (bytes, -q) 819200
real-time priority              (-r) 0
stack size              (kbytes, -s) 10240
cpu time               (seconds, -t) unlimited
max user processes              (-u) 4096
virtual memory          (kbytes, -v) unlimited
file locks                      (-x) unlimited
  1. 如何显示限制的消耗?例如,打开了多少个文件,消耗了多少内存等?

  2. 推论:我如何向不同的用户(而不是“自我”)显示相同的内容?
