When looking for any Harvest related process on the operating system, it can be complicated because there are 4 different types of processes (bkrd, hserver, rtserver, agntd) for which to look. Here's how you can do it with a single command.
CA Harvest SCM all versions and platforms
On Linux or Unix you would use the "ps" command and grep for multiple strings, like this:
ps -ef | grep 'bkrd\|hserver\|rtserver\|agntd'
On Windows you can use Powershell to accomplish the same thing with this command:
tasklist | select-string -pattern "bkrd|hserver|rtserver|agntd"
