Major oversight that needs to be addressed with KILL command, process ID number, and the ps aux output table?

You know, for all the warnings that are given when describing the KILL command, you'd think that they'd make sure to describe every little detail in regards to attaining the correct info when looking up the process ID.

Example: KILL the top process. Run ps aux | grep "top" to find it. Now, here is the oversight that can cause problems...the output table for - ps aux | grep "top" - has the process ID for the TOP process in a different column than in the TOP process table. It's in a different column that's next to another column with numbers that could easily be mistaken for the process ID needed for killing a process.

Now, it may be nitpicking, but isn't that something that should be brought to a students attention when using such powerful commands?

You're right. Attention to detail is very important. We're lazy so we're going to be more likely to just use ps aux | grep top instead of ps ax -o pid,cmd | grep top. Isn't it better that we learn which column is the right one by getting used to the output of the simpler command now when a mistake won't take down the server?
