The shell is bash.
The directory path, /this/is/directory/aa, is actually linked to the path /this/is/link/aa.
So when I cd to the aa directory I am in /this/is/link/aa and there is no /this/is/link/bb hence the error with ls.
My question is how does cd understand relative paths and not return an error the way ls does?
I've got a shared (Windows/multiuser Linux) laptop, and I've got installed World of Warcraft and some steam games in Windows. With steam games, there is (almost) no problems. I've installed steam in Linux, and soft linked the 'steamapps' directory (per-game compatibility is another issue). With WoW, the problem is different. I would like to have almost (but not) all files. Under World of Warcraft, every file and directory must be linked except the Interface directory and WTF/config.wtf file (so every user can play with their own settings and addons). How can I have a mix of linked and not linked files without linking every file? If I link manually every file/dir, when updating from Linux other users and Windows Wow is not updated; when updating from Windows, new files remains "unlinked".

I'm a storage engineer by trade and have mapped a RHEL 4 server, several LUNs. I've mapped each (HBA Initiator) 4 times to seperate fibre channel ports on a storage array.Is there a RH command to see the device mapped 4 times to the target. I would expect to see something in the output that has the subsystems WWN, such as -

View 8 Replies View RelatedI can't seem to find a way to do this, so maybe it's not actually possible, but I was wondering if there was a way to list all files that link to a file.
For example.
touch a
ln a b
ln a c
I want to find out what files link to a (not symlinks, mind you), assuming that this is more complicated (they are spread around to different directories).
I kind of understand about the filesystem storing links in one area and data in another, so I understand it probably takes more work to find a link from a file location than the other way around.
i would like to have clarification from you.

Is there some sort of standards file path convention for installing softwares that I could follow through? For example, I just learnt how to build Nginx from source. But the default binary path set by nginx is "/usr/local/nginx/sbin". I have seen a couple of tutorials which they specify the location of the installed binary and it is very different from those usual default paths. Thus, got me thinking whether is there some form of file path convention that I should follow?Is there some kind of list which states where do those packages on Debian.org Repository usually installed to?

I search online and there are a few people reporting similar issues. There are no resolution on those questions. And I can't seem to find any repositories that have those libraries.

I just thought I should signup, been checking this forum for a while and so far it had answered most of my google searches. I'm on Karmic Ubuntu and this problem keeps annoying me since it will probably damage my hdd. It's like this: I seed a lot of torrents and I'm keeping my external plugged in; most of the time it's innactive since no one is leeching old torrents and it stays mounted in stand by, being a LP model.
Now, whenever I access a folder on my desktop to browse or whatever, Nautilus freezes because it takes time to get my external back from the stand by. The problem is that the desktop folder isn't linked in any way to the external, so why is Nautilus refreshing everything including my externals when it gets started ? I have 3 externals and this happens for them all. Did you guys ever experienced this ? I was wondering if there was a fox around this or something, I'm kinda new to linux graphic interfaces.

I'm interested in modding an open-source turn based game called Advanced Strategic Command or ASC, but to do that I need bunch of libraries. Installing those libraries is very easy in linux, I know but the thing is I'm working with windows in which the building of the libraries is a bit more complex, as you probably know. One of those libraries is the ligsigc++, I'm using VC++ but haven't been successful in building the libsigc++ in VC++. I considered making my life easier with Cygwin (a unix shell for windows) and simply executing ./Configure, Make. I's worked like a charm and the library dll it produced is named cygsigc-2.0-0.dll which made me wonder is compiling a library in cygwin to be linked with VC++ perfectly ok? That is is there any difference in compiling in cygwin and VC++?

View 2 Replies View RelatedI'm a csh user. In my .cshrc or .login files, I'd like to add certain directories to my search PATH, but I'd first like to check if those directories are already in the search path before attempting to add them (so don't add the same directory twice). The following isn't working
Code:
if ( "${PATH}" !~ ~/bin ) then
setenv PATH "${PATH}:$HOME/bin"
endif
The problem is that the if-statements always evaluates to TRUE, meaning that ~/bin is always added to the path, even if it's already in the path.
What am I doing wrong in the above regulat expression, or alternatively, what's an easy way to accomplish the same thing?
I've got a script to recursively create symlinks in my home directory to my settings directory, to keep the files under version control. I would like it to skip files which are already symlinked via a parent directory. That is, if I have these files/directories:

~/settings/foo/
~/settings/foo/bar
, how do I check that ~/foo/bar and ~/settings/foo/bar are the same file?
Edit: D'oh, another few minutes of searching revealed the answer: readlink -f $path
Trying to understand my ruby folder structure? Why my gems are scattered all over and why they aren't recognised commands. I'll explain how my installation looks like first:
/usr/bin/ruby
/usr/bin/ruby1.8
/usr/bin/ruby1.9.1
The first is a soft link to ruby1.9.1 because the "ruby" command didn't work in the terminal. I did the same with "gem". I installed rubygems through downloading, extracting and then running setup.rb here: (I created the "ruby" folder)
/home/pc/ruby/rubygems-1.7.2/setup.rb
/usr/bin/gem
/usr/bin/gem1.8
/usr/bin/gem1.9.1
I installed a few gems with "sudo gem install"
> gem list
*** LOCAL GEMS ***
compass (0.10.6)
haml (3.0.25)
mustache (0.99.3)
rake (0.8.7)
So far so good? Well not quite, as it turns out the command "compass version" doesn't seem to exist. My confusion grows with each folder I look into. The following path doesn't make any sense to me, for example. Why would it be hidden? Why is mustache the only gem inside this folder?
/home/pc/.gem/ruby/1.9.1/cache/mustache-0.99.3.gem
First of all, here is "gem environment", which makes even less sense, because I have definately installed rubygems-1.7.2 like I told you in the first paragraph, but here it shows an ancient version 1.3.7. Why? I installed Ubuntu the day before yesterday.
RubyGems Environment:
- RUBYGEMS VERSION: 1.3.7
- RUBY VERSION: 1.9.2 (2010-08-18 patchlevel 0) [x86_64-linux]
- INSTALLATION DIRECTORY: /var/lib/gems/1.9.1
- RUBY EXECUTABLE: /usr/bin/ruby1.9.1
- EXECUTABLE DIRECTORY: /var/lib/gems/1.9.1/bin
- RUBYGEMS PLATFORMS: .....
Ruby --version returns "ruby 1.8.7"...........
Also, as it turns out, all gems are installed into this folder (mustache too! even though it already is inside the other folder), just as "ruby environment" claims:
/var/lib/gems/1.9.1/gems. But none of these gems work. I can't call any of these, except rake. So here is where I probably made the mistake, I think I used "apt-get install rake" in addition to "gem install rake", because the command "rake" wasn't recognised, and the command prompt suggested it. I may have done so with rubygems too... I'm new to Linux, and I figured that the command prompt knew how to install this stuff properly. It can't be normal that I have to create syslinks all over, right? In Windows I didn't run into this problem.
When I asked about filesystems with compression I got recommendation to try ZFS. Looks like it worth trying, however I find tools that manage ZFS (zfs, zpool) quite overcomplexified - you need to create some volume, then add it, then create filesystem on it. And finally it suddenly created things in root directory like /qqq/test and it uses /var/run/zfs/zfs_socket (strange for a filesystem).
How to use ZFS (with FUSE) without it's complicated things with volumes, just as good filesystem with compression, something like mount -o loop image.zfs /mnt/qqq -t zfs-fuse?
How to setup ZFS as non-root? FUSE usually means "user can use it too" (example: ntfs-3g). I expect something like this:
Can ZFS be more usual FUSE filesystem that I can add to /etc/fstab and user can install and use on its own?
After I reboot my Ubuntu 10.04.2 LTS l machine my device paths change (even the boot drive) and this causes havoc on my two RAID5 arrays. The device paths change and causes a mismatch in my fstab and I have to manually mount both RAID arrays every time. It's quite frustrating and annoying and I would love for it to stop. This even happens for the boot path.
Example: my boot path is /dev/sde5 I reboot my machine and my boot path changes to /dev/sdm5
Why does this happen? And more importantly how can I stop it from happening so it stops messing with my RAIDs?

I want to print, using locate, all the paths that contain the element /bin/ but only one instance of each one. If I issue 'locate /bin/' then I have many screens of text with, for example,
/usr/bin/foo1
/usr/bin/foo2
/home/me/bin/foo3
whereas I want to see only
/usr/bin/foo1
/home/bin/foo3
That is to say, if in two lines /bin/ appears with the same prefix (in the example above the prefixes would be /usr and /home/me) I only want to print the first line. Can I pipe locate to grep to do this? I've mentioned locate because it does not scan the whole disk.
