This awk command pulls URLs from an apache config file, where $x is the config filename. awk '/:8008\/root/ {printf $3 "\t"}' $x The URL that is output by the script looks something like this: ajpv12://hostname.network.company.com:8008/root Is there a way to alter the output so it only shows "hostname" by itself? Do I need to pipe this through awk again to clean it

Is there a flag for the df command to get the total disk space used on all filesystems as one number? I have a server with a lot of mounted shares. I'm looking for a simple way to measure rate of data growth across all shares as one total value.

This snippet of code pulls an array of hostnames from some log files. It has to parse around 3GB of log files, so I'm keen on making it as efficient as possible. Can you think of any way to optimize this to run faster? HOSTS=() for host in $(grep -h -o "[-\.0-9a-z][-\.0-9a-z]*.com" ${TMPDIR}/* | sort | uniq); do HOSTS+=("$host") done

Hey guys, Looking through my book and the web and I am not having any success returning data from a search. I need to have awk search for a string and print the first field which is no problem but now its returning two options as the input data has changed. The change is reliable, I only want the first field if it ends in a regex that I have, and I only want what that regex matches to be printed.

Hi, I have a Sitecom NL-031 USB 3.0 NIC which I'd like to use under centos 6.5, but unfortunately I see no support. Or, I am doing something wrong. According to LKDDb (Linux Kernel Driver DataBase), the correct driver is "CONFIG_USB_NET_AX8817X: ASIX AX88xxx Based USB 2.0 Ethernet Adapters" but obviously, I've grabbed a non matching "iProduct", because mine is

I'm up for a cell phone contract renewal and am considering upgrading my handset. I looked at some devices at my local AT&T store but nothing really jumped out at me. I'm particularly interested in a cell phone that has a reliable ssh client, with ssh-agent and public key authentication abilities. Those of you who administer systems remotely, what mobile ssh client do you recommend?

I have a server that is undergoing some patching soon and would like to make note of any files that have changed after the patching is complete. Can you recommend a tool that uses md5sum snapshots to do a quick before and after test, showing anything that's changed on a particular file system?

Ok, so I figured I''d move this here since IRC isn''t the place for it. Ok, so I have my 40ish servers. Of those, 36 or so of them have hosts entries that need to look like this: 127.0.0.1 localhost 172.x.x.x dbprod1.xxx.com dbprod1 172.x.x.x mgmt01.xxx.com mgmt01 puppet certmaster 172.x.x.x mybox.xxx.com mybox Where mybox is the name of the box. The others have a few

I really like gnu screen and use it everyday but there's one thing that is a bit inconvenient, and that's the odd line wrapping and terminal size issues that seem to pop up. The problem crops up when I type or paste a really long command, and then go back and try to edit it; the text starts to wrap over itself and you have no idea what you are editing. Any fixes for this?

I have a perl script which runs from a cron job. How would you limit the amount of RAM that this script is allowed to consume? Is there a ulimit setting that will accomplish this? If so does ulimit have to be run each time the script is run, or is there a way to set it permanently?

In the section 'Populating FDS with PDC Entry', it instructs the user to run 'net getlocalsid'. This results in the following: [root at mybox logs]# net getlocalsid

I would like to block all DNS queries that come from one particular ip address.
