we can use time in a unix environment to see how long something took...
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)?
in particular i'm interested in peak allocation.

Check Computer Memory Usage EasilyTo open up Resource Monitor, press Windows Key + R and type resmon into the search box. Resource Monitor will tell you exactly how much RAM is being used, what is using it, and allow you to sort the list of apps using it by several different categories.
Entering cat /proc/meminfo in your terminal opens the /proc/meminfo file. This is a virtual file that reports the amount of available and used memory. It contains real-time information about the system's memory usage as well as the buffers and shared memory used by the kernel.
Check the man page for time. You can specify a format string where it is possible to output memory information. For example:
>time -f"mem: %M" some_random_command mem: NNNN
will output maximum resident set size of the process during its lifetime, in Kilobytes.
