General :: When Would Creating A Hard Link Be Useful

May 25, 2011

There are basically two main limitations with hard links:

Hard links normally require that the link and the file reside in the same file system. Only the superuser can create a hard link to a directory.

Thus, symbolic links were introduced to get around the limitations of hard links. So, the question is, are hard links still needed? Might there be situation where they are more useful?

General :: Creating Hard Link To Directory?

Jul 3, 2009

I have heard that creating hard link to a directory is not possible however when reading the man page of "ln" the "-d/-f" option says hard link directories ( super-user only). Thus this mean the super user i.e root can create hard link to directory and not a normal user , If yes then you . Even on specifying the above options I get a operation not permitted for a super user.

General :: Creating A Link To A Deeply Nested Folder Like = /home/username/?

Sep 17, 2009

I have an external hard drive mounted at /media/exthdd/ On that hard drive I have folders: Music, Pictures, Videos, etc. Can I make symbolic links to /media/exthdd/Music/ to say the root directory /_ ? the directory /_ is empty I just want a quick method of typing to get me there much like [cd ~] gets me to my home/username folder. I have my music organized by Artist/Year-Album/Track.Title.mp3 I want to be able to "cd /_" then "ls" and see all Artist folders.

General :: Rsync --link-dest Not Creating Hard Links On External Usb Drive?

Aug 24, 2009

CentOS 5.2 64bit 2.6.18-92.el5xen. Use rsync with --link-dest for nightly backups, works well. Was recently asked to start weekly backups to an external drive for off-site storage. The regular syncing works but hard linking seems to be ignored. So the backup is long with no space saving advantage. Here is an example of the command being run:

rsync --stats -axzvl --numeric-ids --delete --link-dest=/mnt/DISASTERBACKUPS/austinBackups/backups/2009-08-21 /AUSTINBACKUPS/backups/2009-08-24 /mnt/DISASTERBACKUPS/austinBackups/backups/

Software :: Relational Database - Creating Workout Generator?

Dec 11, 2010

I have never worked with databases before, and would like to create one to be a "workout generator." i.e. have a name of workout, list of equipment, list of exercises, and instructions. Then be able to search by any of the above parameters (for example dumbells and pullups) to get a list of options. I assume a relational database is my best option, but my brief looks at SQL etc they seem quite complicated. A GUI frontend and good documentation are highly desired. GTK is also preferred.

Software :: Creating Link To Newly Installed G++?

Dec 7, 2010

I have installed gcc-3.3 & g++-3.3 in ubuntu 9.04. Now I want to change the default compiler as gcc-3.3/g++-3.3. After creating links to newly installed gcc/g++, gcc works fine but g++ doesn't work.

When I give "$which gcc" or "$gcc --version" it works fine, but when I give "$which g++" it gives nothing and also "$g++ --version" it gives an error "the program 'g++' can be found in the following packages: * g++..." When I installed gcc I gave the command "$configure --perfix=/opt/gcc33 --program-suffix=33 --enable-languages=c,c++" . When I give "$which g++33" and "$g++33 --version", work fine.

I tried following:

$export CXX=g++33
$sudo ln -s g++-3.3 g++

Nothing happens. I am very new in Linux and I need to install ns2.1a9b in gcc-3.3.

Ubuntu :: Creating Link To A .java File With Parameters

Oct 24, 2010

I have a Java program (minecraft server) that needs to be run from the command line. The code is:

Code:
java -Xmx512M -Xms512M -jar minecraft_server.jar nogui

To make life easy (i've got the java file in a folder on the desktop) I want to have a shortcut (or similar) sitting on the desktop. I've tried

Code:
ln 'java -Xmx512M -Xms512M -jar minecraft_server.jar nogui' ./../minesraftserver

with single and double quotes but my unix command line skills are pretty basic and this is obviously incorrect.

Ubuntu :: Creating A Link To World Of Warcraft On Windows Partition?

Apr 2, 2011

I have a bit of a problem that I don't understand and would like some help please - I will try and explain the best way I can. I installed Ubuntu using the WUBI installer and so I can access my Windows partition in /host. Using Wine I can run World of Warcraft by going to /host/Program Files/World of Warcraft/WoW.exe But I would like to create a link on my desktop to that file so I do not have to keep going to that path everytime.

The Problem - when I click make link and drag it to my desktop I double click the file (expecting it to just act like a windows shorcut) but it doesn't - it creates some of the files that are in the world of warcraft folder on the desktop and then fails to open with message: Failed to open archive dataart etc...its like it is creating a copy of files on my desktop of what is already in the WoW folder.

Programming :: Link Directories - Symlink Not Updated / Hard Link Not Supported?

Sep 6, 2010

In the ordering of files I keep I need links to directories. Sometimes I even need to move directories to new locations. I have tried using symlinks, but they become dead when I move the directory they point to. I have tried hard links, but I haven't found any Linux file system that would support hard linked directories. How can I achieve that a complex structure of directories (currently with symlinks for directories and hard links for files) keep symlinks live when directories are moved?

- is there any utility that updates symlinks when a directory is moved?

- is there any Linux filesystem that supports hard linked directories?

- is there any good Linux interface to the new NTFS (the only file system I know to support automatically updating directory links, called directory junctions)?

Ubuntu Networking :: Mount To Vista Needed For Apache - Symbolic Link Not Allowed Or Link Target Not Accessible

Apr 26, 2010

I have a problem where I'm using Ubuntu linux to mount a Windows Vista machine's USB drive and access it on the web using Apache. I did have the USB drive plugged into the Linux machine directly and that was working via the web. FollowSymLinks is on in httpd.conf

[Code]....

The mount works and I can see the files (see above) from my regular linux user account. If I make a test file in /mnt and soft link to that, I can see it on the web. So it's just the mount to the vista machine that seems to be a problem. It's supposed to be a simple read-only mount and the apache login should (I think) be able to see the same generic root access permissions.

log from apache: [Mon Apr 26 20:39:42 2010] [error] [client 99.99.99.99] Symbolic link not allowed or link target not accessible: /home/user1/pub_html/Music, referer: https://xx.xx.xx/~user1/music.html

The credentials have a login and password that matches a special read-only account on Vista. I can see the files on the system from Linux, but not via the web. As mentioned above, a different link to the same /mnt area works fine via the web. I've tried several different mount options with no success.

Server :: Database Stopped Showing Up - Files Still There - Restore The Database From The Files?

Jul 8, 2011

I recently moved into a new place and when I hooked up my webserver, I wasn't able to bring up my page, even from localhost. With some digging, it seems that I can't access the database that housed my posts (wordpress installation). I looked for the datadir in MySQL and that directory shows the wordpress directory that should be holding the database and all the files are still there. 1) why the database no longer shows up 2) how to restore the database from the files?
