For us new to linux can anyone explain what this does? Tks Matt > > top gives the processes running on the CPU along with such info as who is the user, and the very important %CPU usage, and it refreshes/updates every few seconds. It's a really good tool for checking on performance slowdowns, etc.
But, on many systems, one needs root to run it, e.g. sudo top So this alternative does much of the same, but doesn't need root privileges. The core of it is the ps aux command - try it out - probably via ps aux | more (actually I use "less" as being more capable than "more" but some systems don't have "less) and then the rest is presentation - and the watch is to repeat it. --henry schaffer -----Original Message----- > From: Linux on 390 Port [mailto:LINUX-390@VM.MARIST.EDU] On Behalf Of > Scott Rohling > Sent: Thursday, July 21, 2011 12:39 PM > To: LINUX-390@VM.MARIST.EDU > Subject: Poor man's top > > I found this buried in some notes.. thought others might enjoy it.
