General :: Extracting Absolute Directory From Type Command?

Sep 26, 2010

I need to extract the absolute directory from the type command when I pass it a program name. E.g.

Code:

>type cat
cat is hashed (/bin/cat)

There is one other case (I believe):

Code:

>type lpr
lpr is /usr/bin/lpr

I thought of using regex, but it returns the whole line, not just the match. In addition, there is no option cited in the man page for type that returns just the command directory.

Note: this is part of my solution to a programming assignment in bash shell scripting.

General :: Command Line - Get Relative Path From Two Absolute Paths In Shell?

May 13, 2010

We have two paths. First one is directory, second either dir or file.

/a/b/c and /a/d/e.txt

Relative path from first path to second will be: ../../d/e.txt

How to get it in linux terminal?

PS: For those who ask "what is use case?" - creating lots of relative symlinks (just as an example)

General :: Extracting Tar File: Cannot Open: No Such File Or Directory?

Jul 19, 2010

I have a remote Debian 5 machine on which I'm trying to extract a tar-file (Django 1.2.1, but that's unimportant). The first 1300 or so files extracts just fine (of about 2800 in total), after which errors liketar: Django-1.2.1/tests/urls.py: Cannot open: No such file or directoryshows up for the rest of the files, finally ending up with atar: Error exit delayed from previous errorsI use the commandtar xzvf Django-1.2.1.tar.gzI've also tried with sudo (but I'm extracting in my home directory, which I should obviusly have permissions to use without). I've tried gunzipping first (runs flawlessly) and then running tar xvf, but to no avail. I've fetched the file using wget:

General :: Use Mkdir Command To Create 'local' Directory In /usr - There Are Error - Cannot Make Directory

Jun 16, 2010

I am a student studying computer science course.

Well, I am facing problem when doing lab questions.

I must use DLXLinux bundled in Bochs (bochs.sourceforge.net).

I am required to use the /usr/local directory.

In /usr directory, there is no directory named 'local' but there is one thing called 'local@'. So, when I try to use mkdir command to create 'local' directory in /usr , there are error "cannot make directory.....".

Look at my screenshot at [url].

Ubuntu :: Finding Folders - Extracting Files - Permission - Directory Does Not Exist

Aug 28, 2010

new to ubuntu and linux, and using Lucid 10.04 LTS ok, i'm trying to get XBMC going, and following a nice step by step instruction on wiki.xbmc.org, but now i'm stuck at this step... In Ubuntu the SVN Repositories are not automatically added. You must add them manually. First, download the SVN Repo Installer from: [URL] Extract it to the ~/.xbmc/plugins/programs directory. If this directory does not exist, run XBMC one time and then exit back to Ubuntu. The directory should now exist.

i ran xbmc once (after the video driver problem was solved, though it messed up my dual monitors, gotta figure that one out yet.) i got the zip file, it's in my downloads. now my newbness really shows... i can't find an 'extract' command for gnome, can't find the .xbmc directory using the file browser, can't figure out how to hunt for folders instead of files, and don't know how to look inside folders i don't have permission to, that is, i don't know if there's a 'sudo' like option for the file browser. i've been searching the forums, but without the correct search terms, i'm wading in an ocean. i really want to give ubuntu an honest try, but i feel like a foreigner. EDIT: btw, up to this point, the forums have been invaluable, you all are great.

General :: Find Directory Older Than X And Mv Directory With Sub Files Command?

Jul 13, 2011

I'm quite new to linux but I have configured a simple ftp server and it's working great. I have a FTP-Shared folder with upload and download subfolders. Under upload's and download's I have identical category subfolders like mp3's, movies, software etc. in both. As the guy's upload, I would like to create a line crontab where I can move all the content under /FTP-Shared/upload/mp3/* older than 14 day's to FTP-Shared/downloads/mp3/ recursively (Like in cp command), but the timestamp must be searched on the first directory and not sub files example: /mp3/Club Dance/CD1/Hallo world.mp3This is how far I got:[root@clients ~]# /usr/bin/find /FTP_Shared/upload/Mp3s/ -depth -mindepth 1 -mtime +14 -type d -exec mv -f {} /FTP_Shared/download/Mp3s/ ;This command moves the directory and files, but it is not recursively

General :: VirtualBox On Wubi Ubuntu Can't Start VMs Due To Incorrectly Handling Absolute Paths?

Jun 27, 2011

I mostly do .Net development in a Windows 7 virtualbox. I use the host for simple things such as web browsing, skype, chat, etc. All things that are fantastically available on Ubuntu which I in many ways prefer. So this has been begging the question for a while: why even use Windows on the host, seems like a Linux host would use less resources (untested) and allow my Windows VMs to run better while allowing me to do my non-development stuff in an interface I prefer.

So easiest way to do this - I downloaded wubi and installed Ubuntu. I installed in it Virtualbox, and then start add and start my VM to get this message: Failed to open a session for the virtual machine VS2010, Could not open the medium '/host/Users/George Mauer/Virtualbox VMs/VS2010/C:/Users/George Mauer/.VirtualBox/HardDisks/VS2010.vdi; VD: error VERR_FILE_NOT_FOUND opening image file '/host/Users/George Mauer/Virtualbox VMs/VS2010/C:/Users/George Mauer/.VirtualBox/HardDisks/VS2010.vdi; (VERR_FILE_NOT_FOUND).

You see what's going on? With wubi, the windows drive gets mounted at /host/ but virtualbox is for some reason appending an absolute path! I would very much like to use the same exact VM file since it would retain Snapshots and I would be able to use it in either windows or Ubuntu mode. However, even if I try to simply mount the drives into a new VM I get an error: Failed to open the hard disk /host/Users/George Mauer/.VirtualBox/HardDisks/VS2010.vdi. Cannot register the hard disk '/host/Users/George Mauer/.VirtualBox/HardDisks/VS2010.vdi' {guid...} because a hard disk '/host/Users/George Mauer/VirtualBox VMs/VS2010/C:/Users/George Mauer.VirtualBox/HardDisks/VS2010.vdi with UUID {guid...} already exists.

This is especially odd since this worked fine with my recently created Android VM, though this might have something to do with the fact that VirtualBox recently changed their default VM storage locations. Any idea how to fix this? My Linux-fu is weak but I seem to remember from CS class something about symbolic links that might be relevant here?
