Experience with:-

  • Linux (Debian, Slackware, RHEL/CentOS, SuSE) - RHCE certified.
  • Solaris (2.6 and up)
  • Windows Server (2000 upwards)
  • Can write in Perl, bash, PHP, C#
  • Cisco switching/routing (both IOS and CatOS) and security gear (PIX, ASA, FWSM, etc.)

...and much more. My CV is available on request, and my LinkedIn profile is here.

Thanks for stopping by!

comment DD-WRT OpenVPN client - cannot get “lan” connected device to route traffic
No problem. I'd start by adding a log line to the end of all your iptables chains, and see if anything's being dropped.

Anyway, in response to the original question, you might find linuxforums.org/articles/using-top-more-efficiently_89.html useful.

comment linux memory usage check in details
From the man page: The total amount of virtual memory used by the task. It includes all code, data and shared libraries plus pages that have been swapped out and pages that have been mapped but not used. I may be misreading, but the phrase pages that have been swapped out is definitely in there.

comment linux memory usage check in details
@mattdm I'm aware of that, but as you say it's not straightforward... otherwise I may just as well have pasted the section out of the man page ;-) RES is the The non-swapped physical memory a task has used... take your point about VIRT though.

comment how to use linux rename
@grawity Cheers for that... I was going on it being the perl-based one, and to keep things to a minimum I went for the shell-only option ;-) Thanks for the tip though!

Odd... I created a few files with the same naming convention you're using, and it works fine. How are you running it?

rename 's/^\d+-\d+\s//g' *.m4a should do the trick, though!

It's just shell... so you should be able to run that straight from the commandline. I'd imagine it is doable with rename, but I've not used it much myself.
