How can I measure memory usage of a command in powershell. I'm thinking something like "Maximum resident memory" GNU time returns with -v flag. Measure-Command only measures time.

I also found this in my searches https://communary.net/2014/10/28/measure-scriptblock/ but its method for measuring memory use is clearly broken. It ouputs 0 kB for programs that definitely use a few megabytes.

My experience of shell scripting is mostly with bash, unfortunately. I found a few solutions that output the momentary memory use of a process using powershell. I tried using Start-Job, but running my same command inside Start-Job seems to kill it right away (It's an exe in the local directory). And anyway, I'm interested in total memory use by the process, not the momentary use at a point in time.

Are you looking for processes memory usage -- or memory usage of a function in your script?

Check out Get-Process It returns System.Diagnostics.Process which have a bunch of properties related to memory usage. The link you had is using the same class.

He's also using [gc] the garbage collector, to try to force memory to be collected early. If you're not testing it's own process, you can skip that. Spawning a child to measure might be more reliable.

Is there a way to run an executable in the local directory and get-process on that?
I figured out my mistake. Powershell, unlike unix shells, seems to run start-job from home directory, so I added -Init ([ScriptBlock]::Create("Set-Location '$pwd'")) to it.
Powershell added the parameter -WorkingDirectory for that
