we can use time
in a unix environment to see how long something took...
我们可以在unix环境中使用时间看看有多长时间......
shell> time some_random_command
real 0m0.709s
user 0m0.008s
sys 0m0.012s
is there an equivalent for recording memory usage of the process(es)?
是否有相应的记录进程的内存使用情况?
in particular i'm interested in peak allocation.
特别是我对峰值分配感兴趣。

Check the man page for time. You can specify a format string where it is possible to output memory information. For example:
查看手册页了解时间。您可以指定可以输出内存信息的格式字符串。例如:
>time -f"mem: %M" some_random_command mem: NNNN
will output maximum resident set size of the process during its lifetime, in Kilobytes.
将在Kilobytes中输出该过程在其生命周期内的最大驻留集大小。

Can you not use ps? e.g. ps v <pid>
will return memory information.
你能用ps吗?例如ps v
