  • How can I sort du -h output by size

    - by Tom Feiner
    I need to get a list of human readable du output. However, du does not have a "sort by size" option, and piping to "sort" doesn't work with the human readable flag. For example, running: du | sort -n -r Outputs a sorted disk usage by size (descending): du |sort -n -r 65108 . 61508 ./dir3 2056 ./dir4 1032 ./dir1 508 ./dir2 However, running it with the human readable flag, does not sort properly: du -h | sort -n -r 508K ./dir2 64M . 61M ./dir3 2.1M ./dir4 1.1M ./dir1 Does anyone know of a way to sort du -h by size?

  • My DNS works! But, what is the simplest way to add something to it?

    - by Alex
    This is my current DNS example.com.db zone file. I followed a tutorial. It works, because when I point to this DNS from another server via resolve.conf, it will actually forward me to the right IP when I do "ping example.com". ; ; BIND data file for example.com ; $TTL 604800 @ IN SOA example.com. info.example.com. ( 2007011501 ; Serial 7200 ; Refresh 120 ; Retry 2419200 ; Expire 604800) ; Default TTL ; @ IN NS ns1.example.com. @ IN NS ns2.example.com. example.com. IN MX 10 mail.example.com. example.com. IN A 192.168.254.1 www IN CNAME example.com. mail IN A 192.168.254.1 ftp IN CNAME example.com. example.com. IN TXT "v=spf1 ip4:192.168.254.1 a mx ~all" mail IN TXT "v=spf1 a -all" Right now, ping example.com....goes to 192.168.254.1. That's great!!! it works! My question is--how can I add something do this file so that when my other servers: ping dbserver1....goes to 44.245.66.222 ping cacheserver1 ....goes to 38.221.44.555 I want to use it like a universal hosts file for my machines.

  • Put Conky behind the desktop icons

    - by Michal Gow
    Maybe I am trying do something impossible, but after hours of Googling I didn't get 100% answer yet. So - it is possible put Conky on Desktop backgroud (behind desktop icons)? The usual config: own_window yes own_window_type normal # (desktop, override) - I have the same result for all this attributes own_window_transparent yes own_window_hints undecorated,below,skip_taskbar,sticky,skip_pager Is giving me Conky with (pseudo)transparent background in front of icons (they are completely hidden behind it, even if in background of Conky is shown background image), while I am trying achieve opposite... My system: SuSE 11.4 KDE 4.4 (Release 3) x86_64

  • How can I fix Problems with interlaced video jerking/flicking when playedback on DVD players? (Mixin

    - by Simon P Stevens
    I'm trying to make a DVD and the final DVD jerks when played on standalone DVD players. It seems to play fine on PCs. I think the problem may be to do with interlacing settings when rendering the final output, but I'll outline the whole editing process I have followed in case I've made a mistake somewhere else. Most of the footage comes from a sony handy cam (one of those mini DVD ones) so isn't great quality. It was set to "high quality" (haha) and 16:9 aspect ratio when it was recorded. I copy the files directly from the mini DVDs onto the hard drive and import them into Cinelerra. In Cinelerra I set the format to 25fps, 720x576, RGBA-8bit, 16:9, interlaced bottom fields first. When I've finished the editing, I add a Fields to frames effect (set to bottom first) to each video track. I render to audio and video separately: Audio: AC3, 128kbps Video: YUV4MPEG steam, video pipe settings: ffmpeg -f yuv4mpegpipe -i - -y -target dvd -flags +ilme+ildct mpeg2video % Cinelerra often crashes during the rendering, so I set it to generate a new video file at each label, and combine them using cat when I've got a sucesful render of each one. Once I've combined them, I use mencoder to re-index them: mencoder -forceidx -oac copy -ovc copy merged.m2v -o mergedReIndexed.m2v I combine the audio and video files using ffmpeg: ffmpeg -i AudioFile.ac3 -i VideoFile.m2v -target dvd -flags +ilme+ildct FinalMovie.mpg Then I build the menus with spumux and I create the DVD file system with dvdauthor, and finally I write it do a dvd-r like this: nice -n -20 growisofs -dvd-compat -speed=2 -Z /dev/dvd -dvd-video -V VIDEO ./ && eject /dev/dvd Originally, when I did it the DVD flickered badly, so as suggested in a guide I added the fields to frames effect in cinelerra. Now it doesn't "flicker", but has become "jerky" when there is lots of motion, particularly when the camera is moving, so the whole background moves. This is what I've tried so far: Removed "mpeg2video" from cinelerra video render pipe. Removed +ilme from render pipe. Removed +ildct from render pipe. Removed +ilme from render audio/video rejoin command. Removed +ildct from render audio/video rejoin command. Added -alt to render pipe. Added -alt to render audio/video rejoin command. Tried with and without the frames to fields effect in Cinelerra. and various combinations of the above. I've also tried this: change the Cinelerra fps to 50, use fields to frames (instead of frames to fields), render to an intermediate QTforlinux jpeg video stream, re-importing that back into Cinelerra, adding a frames to fields effect and then rendering that output as normal (@25fps), and I still have the same problem. Has anyone experienced this "jerking" playback before? Can anyone give any suggestions on how to fix it? (Like I say, it plays back fine on a PC, but not on any of the standalone players I've tried)

  • Mounting both /dev/sda and /dev/sda1 - how can this be?

    - by itsadok
    I work on an Amazon EC2 instance that somebody else set up. We have an EBS volume mounted on /dev/sda, even though the root device is already on /dev/sda1, and we're also using `/dev/sda2' user@server:~$ mount /dev/sda1 on / type ext3 (rw) ... (snip) /dev/sda2 on /mnt type ext3 (rw) /dev/sda on /vol type xfs (rw,noatime) ... This doesn't seem to fit with what I know about the way /dev/ works. How is this possible, and more importantly: will this cause trouble in the future? I'm running ubuntu 9.04 jaunty.

  • soft lockup - CPU#0 stuck for 11s! error with Xen virtual machines

    - by Arun
    Getting a kernel panic with this error on my XEN VPS's. (all on 8.04 LTS) The kernel version on my Dom-0 is 2.6.24-25-xen and the kernel version on the Xen VPS is also 2.6.24-25-xen. I read something about disabling APIC from here http://muffinresearch.co.uk/archives/2008/08/20/ubuntu-bug-soft-lockup-cpu0-stuck-for-11s/ but that doesn't seem to help as well. Anyone experienced this and are there any workarounds? Thanks in advance!

  • iptables to block VPN-traffic if not through tun0

    - by dacrow
    I have a dedicated Webserver running Debian 6 and some Apache, Tomcat, Asterisk and Mail-stuff. Now we needed to add VPN support for a special program. We installed OpenVPN and registered with a VPN provider. The connection works well and we have a virtual tun0 interface for tunneling. To archive the goal for only tunneling a single program through VPN, we start the program with sudo -u username -g groupname command and added a iptables rule to mark all traffic coming from groupname iptables -t mangle -A OUTPUT -m owner --gid-owner groupname -j MARK --set-mark 42 Afterwards we tell iptables to to some SNAT and tell ip route to use special routing table for marked traffic packets. Problem: if the VPN failes, there is a chance that the special to-be-tunneled program communicates over the normal eth0 interface. Desired solution: All marked traffic should not be allowed to go directly through eth0, it has to go through tun0 first. I tried the following commands which didn't work: iptables -A OUTPUT -m owner --gid-owner groupname ! -o tun0 -j REJECT iptables -A OUTPUT -m owner --gid-owner groupname -o eth0 -j REJECT It might be the problem, that the above iptable-rules didn't work due to the fact, that the packets are first marked, then put into tun0 and then transmitted by eth0 while they are still marked.. I don't know how to de-mark them after in tun0 or to tell iptables, that all marked packet may pass eth0, if they where in tun0 before or if they going to the gateway of my VPN provider. Does someone has any idea to a solution? Some config infos: iptables -nL -v --line-numbers -t mangle Chain OUTPUT (policy ACCEPT 11M packets, 9798M bytes) num pkts bytes target prot opt in out source destination 1 591K 50M MARK all -- * * 0.0.0.0/0 0.0.0.0/0 owner GID match 1005 MARK set 0x2a 2 82812 6938K CONNMARK all -- * * 0.0.0.0/0 0.0.0.0/0 owner GID match 1005 CONNMARK save iptables -nL -v --line-numbers -t nat Chain POSTROUTING (policy ACCEPT 393 packets, 23908 bytes) num pkts bytes target prot opt in out source destination 1 15 1052 SNAT all -- * tun0 0.0.0.0/0 0.0.0.0/0 mark match 0x2a to:VPN_IP ip rule add from all fwmark 42 lookup 42 ip route show table 42 default via VPN_IP dev tun0

  • Descending list ordered by file modification time

    - by LanceBaynes
    How can I generate a list of files in a directory [for example, "/mnt/hdd/PUB/"] ordered by the files modification time? [in descending order, the oldest modified file is at the lists end] ls -A -lRt would be great: https://pastebin.com/raw.php?i=AzuSVmrJ But if a file is changed in a directory, it lists the full directory, so the pastebined link isn't good [I don't want a list ordered by "directories", I need a "per file" ordered list] OS: OpenWrt [no Perl - not enough space for it :( + no "stat", or "file" command].

  • How to have a shell script available everywhere I SSH to

    - by aib
    I have a shell script which I simply cannot do without: bar from Theiling Online I use SSH a lot and on a variety of *nix servers. However, I am not a system administrator and usually don't have the time or privileges to install it on every server I connect to. It is apparently a very portable sh script and has command line options to export itself as a shell function, which got me thinking: Could I use one of OpenSSH's subjectively obscure features to export it everywhere I go? My first thought was to assign the source to an environment variable like BAR = "cat -v" and then execute it on the other side as `$BAR`, but 1) I can't even get the cat example to to work locally, 2) I don't know how to put the script's actual multiline source into an environment variable and 3) I have yet to see a machine with PermitUserEnvironment enabled. I guess I could even do with an ssh option to write a file called ~/bar at logon, but a more volatile solution would be better. Calling wget http://.../bar at logon would be unacceptable. Any ideas? P.S. Putty-specific solutions, though I doubt any would exist, are also fine.

  • Deleting another user's diretories from my own

    - by kwatford
    I am a non-root user, and have made a directory into which other users in my group can write. The directory is setgid, so files and directories within it have the same group. I can delete files placed into this directory, but if a user creates a subdirectory with files in it, I can't seem to delete those. Is there something special I can do (other than, say, bothering the user in question or the sysadmin about it) to get rid of this subdirectory?

  • recovering a broken GNOME-desktop in debian wheezy

    - by morgon
    an hour ago I had a working gnome-desktop on my debian system (thinkpad x121e). Then I installed compiz that crashed. After a reboot the gnome-desktop no longer started. Then I did some upgrades with aptitude, all gnome-packages seem to be there, but it is still not working. On startup I get a login-dialog, when I login there is no desktop, only some window-manager running that allows me to start a terminal. When I run "gnome-session" I get the error message "failed to load session "gnome". So how do I get back to a working desktop? I have tried "tasksel install gnome-desktop --new-install" but that just displays a progress window that after half an hour still shows 0%. Can someone help me please? I have tried "

    I was recently added to a group on the unix server. My active screen session has not been update to the new groups: $groups A B C D $screen -r $groups A B C Without closing my screen session is there a way for me to use my new privileges in the screen session?

    I'm attempting to build a system for co-location. I've been running into issues while trying to install CentOS 6.3 System Specs: Motherboard: ASUS m5a99x Process: AMD FX-8120 (8-core Bulldozer) Memory: 2x 4gb G-Skill 2133 running at 1600 I keeps giving me an error message: CPU1: Not Responding. CPU2: Not Responding. CPU3: Not Responding. CPU4: Not Responding. CPU5: Not Responding. CPU6: Not Responding. Then it instantly restarts. I have tried installing it from USB, Multiple DVDs, Multiple Distros. I have also in the bios attempted to disable cores. I was able to disable 2/3 4/5 6/7. I have also ensured that there is zero overclocking. The system works fine in a windows environment. I'm out of ideas.

  • Accidentally deleted /opt/local/bin without backup. Any help?

    - by Aaron
    Hi all, I'm on a Mac OS X 10.5.8 I was recently uninstalling mysql5 from /opt/local/bin. I typed: rm -rf /opt/local/bin mysql* instead of rm -rf /opt/local/bin/mysql* This deleted my entire /opt/local/bin directory which puts me in a bit of a bind. Is there any way to recover these files? If not, I have a friend that is using a similar set of programs, would it be possible to use the contents of his folder? If I end up needing to re-install everything in this folder, what is the best way to go about doing this? Thanks in advance!

  • SCP command Clarification

    - by david.colais
    I'm using the scp commands to pull some files from the remote server and one variation of the command is not working. I have 2 files names one.xml and two.xml in a remote server and I'm pulling these two files into the current dir using the following command: scp [email protected]:/student/class/Intermediate/one.xml . scp [email protected]:/student/class/Intermediate/two.xml . The above command works fine but if I use wildcards to pull all the xml files in a single shot as shown below it returns scp: No match. scp [email protected]:/student/class/Intermediate/*.xml . Why is it working if I pull the files individually and not working if I try to pull using wildcards.

  • Can't access individual samba shares

I have a share with the following in the smb.conf file: [storage] comment = Main storage for all use path = /share public = yes browseable = yes writable = yes printable = no write list = bob root create mask = 0775 guest ok = yes available = yes In Windows Explorer, I can reach the page listing all the shares on the server, but I click on the shares themselves, I get an error saying that the folder cannot be found. I have verified that the folder /share exists and I've also given it 777 permissions so it cannot be due to permissions. What is causing this? I can post more config files if necessary.

  • Auto-rotate rotated images with mogrify

    - by Frank Presencia Fandos
    Some of my images have been taken rotated but kept this data. The problem is that, when using mogrify to convert them from JPG to png, that data seems to dissapear. For showing this problem, I think the best is to show the script and an screenshot. Script with the code. Put it in a text file, give it execution permission, double click, run (from terminal if you wish) and wait a while. All the JPGs in that folder will be converted to png. #! /bin/bash echo "Converting JPG to png. Please don't close this window." mogrify -alpha on -format png *.JPG mogrify -alpha on -format -alpha on png *.jpg It works great and adds an alpha channel. This is personally useful when I edit them later, not to add the channel individually. Now the screenshot that illustrates the problem: As you can see, the original ones' (JPGs) preview is right, the modified preview is wrong, the Shotwell rendering is right and the GIMP edit is wrong and didn't even say the image was rotated, as it uses to do with other images. How can I edit my script to preserve the orientation?

  • Dovecot/Postfix-mysql e-mail Aliases are not correctly forwarded

    I recently set up Dovecot/postfix-mysql on my Debian Squeeze Server and I have a bit of a problem. When ever I send a email to an alias ([email protected] forwarded to [email protected] for example) Postfix (or Dovecot, I'm not quite sure) puts this email into a Mailbox rather than forwarding it to the real Mail-Adress. I have tested all the MySQL queries and they all behave the way I intend them to do. foobar dovecot: deliver([email protected]): msgid=<000001385b464c9a-e40af11e-3bf4-49f6-903d-1d2369f6bfb6-000000@barfoo: saved mail to INBOX master.cf main.cf Keep in mind that normal E-Mail sending and receiving works just fine!
