this is a ibm z/vm system, so a bit alien... operator is struggling to renew a certificate without help. He did one system fine but couldn't find the file on the other. the problem? he tried to access a directory, mistyped it, didn't read the error message, went straight to the import and obviously failed.
sent me a couple screenshots, first line says "cd /some/place" and the second line says "No such file or directory" and all the other lines are errors because copy and paste only works when all steps are done correctly...
when I was a technical instructor, I started the first day of the course writing RTFM on the left and RTFS (where S stands for Screen) on the right on the blackboard (or whiteboard), and let it there for the entire course. When someone asked something that the screen would answer I pointed there...
change of subject, one missing space during a change broke a system and we spent more time fixing the issue caused by the space than doing the change...
it's a VSE system, even more alien than z/VM, and we were installing libs for IPv6 on it. It's unlike anything you all have seen, required editing a file, submitting it, editing another file, submit again, a dozen times (really). and the files have 80 column limit, and if you need more than that you need a special char (the continuation char) exact on line 80
what happens if the continuation char isn't on column 80? Nothing on the edit, nothing after submit, it does not work when you restart the system. To fix the issue you edit the file and submit again, and start the job again. But what if the job is the equivalent of init on a unix? yep, that... system does not boot (or IPL, as we say on VSE). To fix you have to edit the file and submit again, but you cannot because the system is down.
we spent an hour trying different workarounds to finally get the system up on "safe mode", submitted the fixed file, and it went ok.
