Cron job Powershell Script

Hello all. I’m hoping someone can help with my syntax here. I’ve been wanting to implement this script for a while, finally set to it today. Manual invocation works just fine. But when I tried to set it up with cron it just doesn’t run.

What I have done:

I have edited crontab -e with

0 */6 * * * pwsh /Applications/Upgradinatorr/upgradinatorr.ps1 -apps radarr,sonarr

I have added /usr/sbin/cron & Terminal to Full Disk Access

I set it around 3-4p. Didn’t run at 6p or 12a.

I’m assuming it’s because of the extra pwsh command there but I don’t know what I’m doing so…

Any advice would be greatly appreciated!!

Mac mini, macOS 14.4

Homebrew should have installed the pwsh binary in /opt/homebrew/bin on an M-series Apple Silicon Mac, or /usr/local/bin on an Intel Mac. Use that shorter path for the Powershell binary in hopes that Cron can resolve it.

Cron doesn't know where to find Powershell (pwsh). Try using the full path to pwsh prior to your script name.

Powershell might be your only recourse on Windows, but it is not the de facto, nor de jure recommended scripting solution for macOS and you will find an absolute dearth of support here for it. MacOS, being a UNIX operating system has several supported scripting solutions available as alternatives to Powershell, and a wider audience able to provide support here in these communities.

So I've done a little more digging and the command should be something like

0 */6 * * * /usr/local/microsoft/powershell/7/pwsh /Applications/Upgradinatorr/upgradinatorr.ps1 -apps radarr,sonarr >/tmp/stdout.log 2>/tmp/stderr.log

If I read it right. How's that look to you?

I didn't find it exactly there but I found this:

0 */6 * * * /usr/local/microsoft/powershell/7/pwsh/Applications/Upgradinatorr/upgradinatorr.ps1 -apps radarr,sonarr

I installed via Homebrew so thusly?

0 */6 * * * /opt/homebrew/Caskroom/powershell/7.4.1/powershell-7.4.1-osx-arm64.pkg/Applications/Upgradinatorr/upgradinatorr.ps1 -apps radarr,sonarr

Actually just poking around I see an alias of that pwsh in /usr/local/bin but what it points to is the one I found first

Yes, whatever works. 🤓 That /usr/local/bin/pwsh should have worked in cron too.
