Is there a way to run a command (e.g. ps aux|grep someprocess) for n times?
Something like:
run -n 10 'ps aux|grep someprocess'
I want to use it interactively.
Update: The reason I am asking this is, that I do work on a lot of machines and I don't want to import all my adaped scripts etc into every box to get the same functionality accross every machine.
I have file servers which are used to store files. Files might reside there for a week, or for a year. Unfortunately, when I remove files from the server, df command doesn't reflect the freed up space. So eventually, the server gets filled up (df shows 99%), and my script doesn't send any more files there, except there might be a few dozen GB of free space on there.
I got noatime flag on the mounted partitions if that makes any difference.
I have configured Apache to send back a 200 response without serving any file with this configuration line
Redirect 200 /hello
Can I do this with Nginx? I don't want to serve a file, I just want the server to respond with a 200 (I'm just logging the request).
I know I can add an index file and achieve the same thing, but doing it in the config means there's one less thing that can go wrong.
I'm running Windows 7 on a dual core, x64 AMD with 8 GB RAM.
Do I even need a page file?
Will removing it help or hurt performance?
Would it make a difference if this is a server or a desktop?
Does Windows 7 vs. Windows 2008 make a difference with a page file?
There's been a number of questions regarding disk cloning tools and dd has been suggested at least once. I've already considered using dd myself, mainly because ease of use, and that it's readily available on pretty much all bootable Linux distributions.
What is the best way to use dd for cloning a disk? I did a quick Google search, and the first result was an apparent failed attempt. Is there anything I need to do after using dd, i.e. is there anything that CAN'T be read using dd?
