Good observation. So, I thought I would check out your theory.
find . -type f | xargs grep QSYSOPR4
it lists 5 files that contain this text, then it just sits there
awhile. Probably at least a minute or two and the $ finally returns.
Interesting since there are only 5 files in the directory. What is
taking so long for the $ to appear?
As you can tell, I don't use QSHELL very much and forgot to pay
attention to the $.
