  • How can I automatically update the title in an xterm running screen?

    - by Nathan Fellman
    This is a bit of a followup to this question. I'm working in tcsh within GNU screen in an xterm. I have the following in my .cshrc: alias res_t 'xtset -t %h:%d "(%u:%g)" %e' # reset titlebar res_t # reset title right now alias precmd res_t And this works fine! However, when I run screen I see that the title doesn't get updated with the current directory. How can I make screen update the xterm title?

  • eCryptFS: How to mount a backup of an encrypted home dir?

    - by Boldewyn
    I use eCryptFS to encrypt the home directory of my laptop. My backup script copies the encrypted files to a server (together with everything else in (home/.ecryptfs). How can I mount the encrypted files of the backup? I'd like to verify that I can do that, and that everything is in place. My naive try with mount -t ecryptfs /backup/home/.ecryptfs/boldewyn /mnt/test didn't work, eCryptFS wanted to create a new partition.

  • RPM with RHEL: install 2 version of same package / different arch

    - by Nicolas Tourneur
    I think the title is pretty self explanatory :) Is it possible, under RHEL (v 5) to install 2 instances of the same packages with 32 bit support for one and 64 bits support for the other one? Obviously, the running host has a 64 bit kernel and has the compatibility libraries required. (in this case, we would need a 64 bits JDK and a 32 bits one). If yes, are there any special rpm flag to use (change of installation directory for instance)? Thanks in advance,

  • How to delete everything except .svn directories?

    - by Arek
    I have quite complex directory tree. There are many subdirectories, in those subdirectories beside other files and directories are ".svn" directories. Now, under linux I want to delete all files and directories except the .svn directories. I found many solutions about opposite behaviour - deleting all .svn directories in the tree. Can somebody quote me the correct answer for deleting everything except .svn?

  • Linux - What do the common root folder names mean?

    - by Josh
    I am rather new to linux, but I have installed a few different flavors. I noticed they all have similar folder names in the root directory bin boot dev etc home lib lost+found media mnt opt proc root sbin selinux srv sys tmp usr var I googled around, but couldn't find anywhere that explained the purpose of each of these. I understand a couple, but could anyone point me somewhere or give a quick breakdown of the common ones.

  • Apache ignore my .htaccess 'dontlog' option

    - by Emilio
    I wrote .htaccess in file dir/subdir to don't log URI requests in this particular directory. The .htaccess is actually executed by apache (if i write deny from , it works), but if the file contains only this rule: SetEnvIf Request_URI "^dir/subdir" dontlog Don't work. AllowOverride All and mod_rewrite are enabled. What can be the problem? Sorry for my bad english.

  • Why does writing a file to an NFS share send a COMMIT operation to the NFS server?

    - by Antonis Christofides
    I have a Debian squeeze (2.6.32-5-amd64) which is at the same time a NFS4 server and client (it mounts itself through NFS4). The local directory that leads directly to disk is /nfs4exports/mydir, whereas /nfs4mounts/mydir is the same thing mounted through NFS, using the machine's external IP address. Here is the line from fstab: 192.168.1.75:/mydir /nfs4mounts/mydir nfs4 soft 0 0 I have an application that writes many small files. If I write directly to /nfs4exports/mydir, it writes thousands of files per second; but if I write to /nfs4mounts/mydir, it writes 4 files per second or so. I can greatly increase speed if I add async to /etc/exports. (Writing a single large file to the NFS-mounted directory goes at more than 100 MB/s.) I examine the server statistics and I see that whenever a file is written, it is "committed" (this also happens with NFSv3): root@debianvboxtest:~# mount -t nfs4 192.168.1.75:/mydir /mnt root@debianvboxtest:~# nfsstat|grep -A 2 'nfs v4 operations' Server nfs v4 operations: op0-unused op1-unused op2-future access close commit 0 0% 0 0% 0 0% 10 4% 1 0% 1 0% root@debianvboxtest:~# echo 'hello' >/mnt/test1056 root@debianvboxtest:~# nfsstat|grep -A 2 'nfs v4 operations' Server nfs v4 operations: op0-unused op1-unused op2-future access close commit 0 0% 0 0% 0 0% 11 4% 2 0% 2 0% Now in the RFC, I read this: The COMMIT operation is similar in operation and semantics to the POSIX fsync(2) system call that synchronizes a file's state with the disk (file data and metadata is flushed to disk or stable storage). COMMIT performs the same operation for a client, flushing any unsynchronized data and metadata on the server to the server's disk or stable storage for the specified file. I don't understand why the client commits. I don't think that the "echo" shell built-in command runs fsync; if echo wrote to a local file and then the machine went down, the file might be lost. In contrast, the NFS client appears to be sending a COMMIT upon completion of the echo. Why? I am reluctant to use the async NFS server option, because it would apparently ignore COMMIT. I feel as if I had a local filesystem and I had to choose between syncing every file upon close and ignoring fsync altogether. What have I understood wrong?

  • 2Wire USB Network Adapter Not Working With Windows 7

    - by Andrew
    I installed Windows 7 on a separate drive, and everything works fine, but I can't get the above network adapter to work properly. It's displayed in Device Manager as a USB device, and I have the driver that makes it function in Vista, but when I run the Driver Wizard and direct it to directory where I have the Vista driver, it almost immediately says "Can't install driver." Is there any work around to this?

  • How can I modify keyboard shortcuts for Firefox?

    - by e.James
    I recently started using Firefox as my primary web browser, and I would like to change some of the default keyboard shortcuts, especially the ones used to switch between tabs. Can this be done? I took a peek through the Firefox directory in "Application Support", as well as the application bundle itself, but nothing jumped out. Google searches have also proved fruitless. Any help is appreciated! Update: I'm running Firefox version 3.6 for Mac OS 10.6.2

    Feeling kinda dumb right now: Why is my contional always true? I've tried # this should let me know what's not a directory or # symbolic link. whoa=`find ${MUSICDIR} ! -type l ! -type d | wc -l` # I would expect if it's 0 (meaning nothing was found) that # one of these statements would evaluate to false, but so far # it's always evaluating to true if [[ "${whoa}" != "0" ]] if [[ ${whoa} -gt 0 ]] What am I missing?

  • Thinkpad speaker turns mute - Linux Codec issue?

    - by Curlew
    At some point a few days ago the speakers on my Lenovo Thinkpad T410 (Model number: 2537A11) suddenly stopped working randomly. This error happens every time I watch a video or listen to a music file. The sound just abruptly stops. At the moment, I can't produce a single sound no matter what I do. I am using Debian GNU/Linux on this laptop and there doesn't appear to be anything else wrong (the fan is working, no abnormal heat (staying around ~40°C), no other obvious errors or problems). Here is the output of a nice program someone pointed me to: martin@martin:~/Downloads$ sudo python run.py --monitor Using temporary directory: /dev/shm/hda-analyzer You may remove this directory when finished or if you like to download the most recent copy of hda-analyzer tool.

Suggest a bigger bdl_pos_adj. I changed the bdl_pos_adj to various numbers (-1, 0, 64, 1024) and either there is no change at all or dmesg reports that the adjustment is too big. I wonder if this bdl_pos_adj is the real reason for the error. Here is my hardware information provided by alsa-info.sh website. Okay, i did some serious testing and even installed Windows and now i officially conclude that this is a hard-ware related issue with my Laptop speakers. Reason: The error occurs in my installed Debian Linux, an Ubuntu Live distribution and Windows XP No error-message appears in all of the OS. The sound just keeps running and i can't hear a thing. I tested different setups, including OSS, ALSA and the pulseaudio server on top If i use my new usb-headphones i can hear sound all the time without any sudden silences. So obviously, although hard to believe, my laptop speakers are not okay (never heard of similar cases). I'll award the bounty to anyone who can point me to good tutorials or the procedure how to exchange my T410 speakers (i still have warranty. The laptop was bought in Germany, but now i am in Denmark). Or to someone who can explain me the output from hda-analyzer (big log above).

  • Tool or script to detect moved or renamed files on Linux prior to a backup

    - by Pharaun
    Basically I am searching to see if there exists a tool or script that can detect moved or renamed files so that I can get a list of renamed/moved files and apply the same operation on the other end of the network to conserve on bandwidth. Basically disk storage is cheap but bandwidth isn't, and the problem is that the files often will be reorganized or moved around into a better directory structure thus when you use rsync to do the backup, rsync won't notice that its a renamed or moved file and re-transmission it over the network all over again despite having the same file on the other end. So I am wondering if there exists a script or tool that can record where all the files are and their names, then just prior to a backup, it would rescan and detect moved or renamed files, then I can take that list and re-apply the move/rename operation on the other side. Here's a list of the "general" features of the files: Large unchanging files They can be renamed or moved around [Edit:] These all are good answers, and what I end up doing in the end was looking at all of the answers and will be writing some code to deal with this. Basically what I am thinking/working on now is: Using something like AIDE for the "initial" scan and enable me to keep checksums on the files because they are supposed to never change, so it would aid on detecting corruption. Creating an inotify daemon that would monitor these files/directory and recording any changes relating to renames & moving the files around to a log file. There are some edge cases where inotify might fail to record that something happened to the file system, thus there is a final step of using find to search the file system for files that has a change time latter than the last backup. This has several benefits: Checksums/etc from AIDE to be able to check/make sure that some media did not get corrupt Inotify keeps resource usage low and no need to re-scan the filesystem over and over No need to patch rsync; If I have to patch things I can, but I would prefer to avoid patching things to keep the burden lower, (IE don't need to re-patch everytime there is an update). I've used Unison before and its really nice, however I could've sworn that Unison does keep copies around on the filesystem and that its "archive" files can grow to be rather large?
