  • mounts aren't case-sensitive

    - by Asi
    I mounted a few drives from Linux boxes in my network, but those mounts aren't case-sensitive. The mount command I used ( from the man mount.cifs, case-sensitive should be the default ): mount //10.0.1.10/remote_folder /local_folder -t cifs -o username=xxxx,password=xxxx but those mounts aren't sensitive. for example doing: ls -l /local_folder/testfile.txt ls -l /local_folder/TESTFILE.TXT give's the same result... instead of 'file not found' Couple of important points: All drives are running on Linux machines. My local machine is running Fedora 18 and it is case-sensitive for ANY folder/file expect the mounted drives. All drive/mounts are case-sensitive when when doing SSH. So if I SSH from my local machine to a remote machine, doing ls -l /local_folder/TESTFILE.TXT will say file not found as it should. So I believe the issue is in my local machine and not in the way I did the mount. but I'm not sure where to look next (I'm new to Linux)

  • Where are ghostscript options / switches documented?

    - by sdaau
    I know there is a Ghostscript option, for instance -dPDFSETTINGS=/screen - where is that documented? How can I see what other options it accepts, appart from screen? Also, -dMaxSubsetPct=100 - what does it do? I open man gs, search for PDFSET, I get "Pattern not found". I type in a search engine, I get a myriad of personal webpages, no documentation hits. Can anyone help with a link? Many thanks in advance, Cheers! EDIT: also see this related post: Querying Ghostscript for the default options/settings of an output device (such as 'pdfwrite' or 'tiffg4') - Stack Overflow ... for getting a list of supported options for a given device.

  • Creating a FAT file system and save it into a file in GNU/linux?

    - by RubenT
    I tell you my problem: I want to create a FAT file system and save it into a so I can mount it in linux using something like: sudo mount -t msdos <file> <dest_folder> Maybe I'm wrong and this cannot be done. Anyway, the problem is this: I'm trying to create the file containing a FAT file system, and I'm running this command: sudo mkfs.vfat -F 32 -r 112 -S 512 -v -C "test.fat" 100 That, accordingly to the mkfs man page, will create a FAT32 file system with 112 rootdir entries, logical sector size of 512 bytes, 100 blocks in total, and save it into "test.fat". But it fails, and the bash tells me: mkfs.vfat: unable to create test.fat What is going on? I think I am misunderstanding how mkfs works and how to use it. It is possible to write a filesystem into a file?

  • Encrypt tar file asymmetrically

    - by DerMike
    I want to achieve something like tar -c directory | openssl foo > encrypted_tarfile.dat I need the openssl tool to use public key encryption. I found an earlier question about symmetric encryption at the command promt (sic!), which does not suffice. I did take a look in the openssl(1) man page and only found symmetric encryption. Does openssl really not support asymmetric encryption? Basically many users are supposed to create their encrypted tar files and store them in a central location, but only few are allowed to read them.

  • Moving only the contents of a map and not the map itself on linux

    - by WebDevHobo
    Using the cp command, one can move files and folders on linux. I want to make a new user and move the contents of the skeleton map to their home directory. I use this command: cp -r /etc/skel/ /home/testuser/ However, this only creates a skel folder in testuser. The idea is that the contents of the /etc/skel folder be copied to /home/testuser, and not that a map be made in /home/testuser with those contents. I've checked the man page: Link, but nothing on there really seemed like the solution to me. Is there a way to do this, or do files really need to be moved manually, 1 by 1?

  • Need to set mailx variable to specify the From address

    - by user256817
    Running Oracle Linux 5.8 (which is just re-branded RedHat EL 5.8) I must change the From address. But we have scripts that use mailx which cannot be re-written to use any extra flags, so I'd like to use internal variables instead, which I see on the linux.die.net manpage on mailx is an alternative to the -r flag: -r address Sets the From address. Overrides any from variable specified in environment or startup files. Tilde escapes are disabled. The -r address options are passed to the mail transfer agent unless SMTP is used. This option exists for compatibility only; it is recommended to set the from variable directly instead. (Source: http://linux.die.net/man/1/mailx) How can we use these mailx variables? I tried adding this to /root/.mailrc, no go: set [email protected] I also added that to /etc/mail.rc with no gold. So I am turning to you, SuperUsers...

  • Security and encryption with OpenVPN

    - by Chris Tenet
    The UK government is trying to implement man-in-the-middle attack systems in order to capture header data in all packets. They are also equipping the "black boxes" they will use with technology to see encrypted data (see the Communications Data Bill). I use a VPN to increase my privacy. It uses OpenVPN, which in turn uses the OpenSSL libraries for encrypting data. Will the government be able to see all the data going through the VPN connection? Note: the VPN server is located in Sweden, if that makes a difference.

  • dhclient and dhcpcd the real difference

    - by rubixibuc
    I can't figure out the difference from just the man pages. I can see what is a daemon and one is a client, but what does that mean practically when using the commands? Also what is the difference between the client and daemon in this case, not just the terms (client and daemon) but functionally wise? EDIT: How are the tasks divided, if the client updates the information on the client, what is the purpose of the daemon. I'm talking about the client daemon in this case dhcpcd not dhcpd. Both come installed by default with some versions of Linux and seem to share the duties of the dhcp client. NAME dhcpcd - DHCP client daemon Name dhclient - Dynamic Host Configuration Protocol Client

  • Why does subshell not inherit exported variable (PS1)?

    - by amn
    After some debugging I finally narrowed down the problem as to why my X session xterm prompt does not appear according to my PS1 setting. If I run sh -c env, it doesn't even show PS1 in the list. Why? export PS1='test' sh -c env # No PS1 in the list, default prompt appearance (shell name + version) Substituting sh with bash yields same result, alas the behavior appears to be the same for both shells/modes. As far as I understood from man bash, the environment resulting from command run by shell with -c should include the exported variables. And it does - exporting FOOBAR results in FOOBAR listed in env run by subshell. It appears that the story is different if the variable is PS1 however. What is going on? I want my prompt propagated throughout the process tree and system. For matters sake, it is set in /etc/profile.d/user.sh (a file I created myself) with the following: PS1='\u@\H \w \$ ' export PS1 I am running Arch Linux (updated yesterday.)

  • Zsh, directory tab-completion with prefix

    - by nifty
    I have a directory where I put all my projects in, let's say it's ~/projects as an example. I've made a command called s which takes one argument, and moves me into that directory. E.g.: s foo moves me to ~/projects/foo. What I'd like is to have a completion command of some sorts, which would act like cd so I could do keep hitting tab to go further into the ~/projects/... directories. Basically, cd with a prefix which is always present. I've looked into zstyle completion in man zshcompsys, but realized I just don't know enough about it to understand it properly.

  • Linux - Multiple service statuses with one command

    - by Jimbo
    I'm trying to retrieve a list of multiple service statuses in Unix. I'm using the service command: man page. The statuses all start with the transmission-daemon string, for example. I require the ability to list multiple services' statuses, with a single command. Here is what I'm currently trying (and failing) with: Here I'm trying to grab a list of statuses using grep. service $(ls /etc/init.d | grep "transmission-daemon") status Here I'm trying to list all statuses, and then grep for them. service --status-all | grep "transmission-daemon" This produces the following, which isn't much help: How can I effectively achieve what I require with a single command, so that I can then continue piping to awk for further customisation? Desired example output: transmission-daemon started transmission-daemon2 stopped transmission-daemon3 started

  • How to call a program and exit from the shell (the caller) when program is active?

    - by Jack
    I want to run a program with GUI, by typing into konsole: foo args … and exit from the shell (that's the caller) when the program (foo) is active. How do I this? Is there a Linux/Unix built-in command/program to do it? I'm not a shell-man, really. I know that it's possible by writing a small program in C or C++ (any other programming language with small I/O interface on POSIX) programming language with the fork() and one-of exec*() function family. It may take some time; I'll do it only if there is no native solution. Sorry for my bad English; it's not my native language. Also, not sure on tags, please edit for me, if I'm wrong. If it matters, I'm using OpenSUSE 10.x.

  • How to change defaulp pdf viewer for all users in command line

    - by dodecaplex
    I'm using Debian squeeze with Gnome Desktop for all my users. I have a group of machines to set up so that all users should use xpdf as a default viewer (rather than evince). I want this set up to be done by command line (even better, using puppet). I know about xpg-mime command, but the man page says that the default command should not be used as root. I could manually tweek the /etc/gnome/defaults.list files, but I'm looking for a single command I could run to perform the setting without an editor interaction. Any idea ?

  • Spam is Killing Me - Can I use GMail as a spam filter?

    - by kirkouimet
    I'm getting at least 50 Viagra ads a day and it's driving me insane. I currently have a hosted MS Exchange account and a Gmail account. My Gmail account forwards to my Exchange account. Both of my addresses are used evenly, and it has been really nice to have all of my e-mail end up in my Exchange box. I like replying from one address consistently, which is my Exchange address. Spam sent to my Gmail address is always caught, where spam sent to my Exchange is getting passed straight through to me. I don't want to have two spam filtration systems that have quarantines that I need to check frequently for false positives. Here is my question: Can I setup my MX records such that all e-mail sent to my Exchange address is forwarded to my Gmail account, which will then forward it to my Exchange account? Kind of like using Gmail as the middle man.

  • how do I use tar -C on Snow Leopard when creating an archive ?

    - by ssc
    The man page states -C directory In c and r mode, this changes the directory before adding the following files. However, tar does not change to the directory I specify, but instead reports tar: <folder name>: Cannot stat: No such file or directory for every folder in the directory I run the tar command in. Do I really have to do something like cd <folder> && tar ... && cd - or is there a way to get this work ?

  • Remove DRM From a WMV file I own

    - by Rev
    Alright, first, let me explain. I purchased some content through Microsoft's Zune/Xbox Video service, and man that was a mistake. After trying several times to get the video to play, I received an error along the lines of "out of licenses." Lucky for me, I was able to recover the file I was looking for off of a backup, but now I'm having problems playing it. It works fine in Windows Media Player, but not in Zune or Xbox Video (on Windows 8). I contacted Zune's customer support, and of course they couldn't help me. So, I legally own the content, I just want to be able to play it where I want to play it. It's ridiculous that I can't. I know there are ways to do this out there, I just can't figure it out (I keep getting directed to this piece of junk thing called Almedia, which kind of seems to work, but was only putting out audio in the demo version). Thanks!

  • How do I mount a sparse disk image permanently?

    - by Mike
    On Mac OS X 10.6.7, when I mount a sparse disk image (either by double-clicking it or using hdid from the command line), the image: Appears on my desktop Needs to be re-mounted every time I log in I'd like to set up the equivalent of an /etc/fstab which will mount the image when the system boots, and make it permanent - so I don't have to worry if my symbolic links will resolve or not. Is this more trouble than it's worth on a Mac? I noticed that there is no /etc/fstab, and /etc/fstab.hd contains a dire warning: IGNORE THIS FILE. This file does nothing, contains no useful data, and might go away in future releases. Do not depend on this file or its contents. I tried sudo hdid -notremovable <image>, which seemed like half of what I wanted (according to man hdid), but it failed with an error: hdid: attach failed - no mountable file systems.

  • How do I use XQuartz with ssh on OS X?

    - by cwd
    I've downloaded the latest stable version of XQuartz on my Snow Leopard machine, and I'm trying to make an ssh connection with X forwarding but X11 keeps opening. How can I get OS X to use XQuartz? I had X11 installed I downloaded and installed XQuartz X11 is not open / running XQuartz is open and running I try and connect to a remote system using iTerm2: ssh user@remote -X X11 opens. XQuartz is still open, but I doubt it is doing anything. I also tried moving X11 to the trash but then the ssh connection will not complete, even though XQuartz is open. I also get the two warnings which I don't understand how to fix, even after reading the ssh man page. Warning: untrusted X11 forwarding setup failed: xauth key data not generated Warning: No xauth data; using fake authentication data for X11 forwarding.

  • Dividing with Gnu's bc

    - by Boldewyn
    I'm just starting with Gnu's bc and I'm stuck at the very beginning (very discouraging...). I want to divide two numbers and get a float as result: $bc bc 1.06.94 Copyright 1991-1994, 1997, 1998, 2000, 2004, 2006 Free Software Foundation, Inc.

Obviously this is either not true or I'm missing something. Googling hasn't brought up any new insights (besides that 'BC' can also stand for 'British Columbia'). Do you see my error? Better yet, do you know any good references/tutorials to bc?

  • mac os x, find all symbolic links that point to files on a different volume

    - by Eddified
    In my ~ dir, I have some symlinks that point to "/Volumes/Macintosh HD 2/..." and I want to find them all recursively. A look at the man page for 'find' says the '-lname' argument will search the symbolic link contents. It appears to work, but not recursively: $ pwd /Users/myusername $ sudo find . -lname '/Volumes*' $ cd Documents/ $ sudo find . -lname '/Volumes*' ./Documents on Win7 ./work.rtf What's going on? How can I make this work recursively? -- The 'find' program is supposed to always work recursively.

  • What does the [0/0] indicator mean when entering copy mode in tmux?

    - by bps
    When entering copy mode in tmux, an indicator in the upper right corner shows "[0/0]". I can't find any documentation in the man page about what these numbers mean, and it's difficult to search since Google throws away the brackets and slash. This is generated by window_copy_write_line() in window-copy.c: if (py == 0) { size = xsnprintf(hdr, sizeof hdr, "[%u/%u]", data->oy, screen_hsize(data->backing)); if (size > screen_size_x(s)) size = screen_size_x(s); screen_write_cursormove(ctx, screen_size_x(s) - size, 0); screen_write_puts(ctx, &gc, "%s", hdr); but the variable names aren't very instructive to someone who isn't familiar with the code. Any hints as to what these numbers mean?

  • How do I turn of "auto-echo" in bash when I 'cd'?

    - by Avery Chan
    I don't know when this started happening but now, every time I cd to a directory it echoes the path right before it changes directories. This happens when I log into a server but doesn't happen on my local machine. The server is running Linux. My local machine is running Mac OS X. I searched the Google as well as looked at the bash man page but I couldn't find anything. My .bashrc/.bash_profile doesn't have anything related to 'cd' (that I know of). How do I modify this "feature"?

    I need to use my university's ssh access and run my programs there for testing. I don't have sudo access there. It doesn't have vncserver there either. I would work with vim and make but I need git at least. Now I am looking into rsync to sync my current source directory into a remote directory and I'll ssh into the directory and run my make file to test it. I am looking at the man page of rsync and it looks very complicated. Can anyone please help me with this? I have googled in superuser and all commands seem different for different cases. Can anyone please help me with this?

  • Disable writing RAID degraded mode

    - by jolivier
    I have a RAID5 with 5 disks on my machine and suspect the motherboard chipset to fail at some points and make my raid going in degraded mode. Last time it happened I noticed it on the failure of the 2nd drive connected to the same chipset and lost a lot of data. So I would like to prevent this, and especially I would like to have mdadm disable writes on the raid if one of the disk fails. So that in between I get notified, I recover and can use my system again. Sadly I could not find it in man mdadm so I was wondering if this is possible via a tool or hidden option since for me it looks like a standard feature of a RAID system. If this is not possible I would also be happy with a solution to stop the raid if degraded.
