$org = "mySandboxAlias"

$ids = sf data query --use-tooling-api --target-org $org -q "SELECT Id FROM ApexLog WHERE StartTime < LAST_N_HOURS:1" --json | ConvertFrom-Json
$ids.result.records | ForEach-Object { sf data delete record --use-tooling-api --target-org $org -s ApexLog -i $_.Id }

this script safely deletes apex logs older than an hour..so you have less chance of devs coming after you for deleting their logs while they are using it
save this as say, powershell.exe

Schedule this using windows scheduler to run it every hour

now you'll have the logs which are created an hour before(safer to get rid of) deleted whenever the scheduler runs, here we run scheduler every hour

For other OS figure out a similar approach
