Ubuntu :: 10.10 - Cannot Detect Subdirectory (Bash CD Error)
Dec 21, 2010
I'm trying to change to a subdirectory:
Code:
tony@advent:~/scratch$ cd Home-Arch
bash: cd: Home-Arch: No such file or directory
So I list the contents of the current directory:
Code:
tony@advent:~/scratch$ ls
duhome Home-Arch qcad_1.dxf qcad_1.svg runme stdout
OK, I assume I have mis-typed the subdirectory name in ways I cannot detect, so I copy the sub-directory name from the output of the 'ls' command, while within the terminal window, and paste it into the next 'cd' command:
Code:
tony@advent:~/scratch$ cd Home-Arch
bash: cd: Home-Arch: No such file or directory
I browse the directory and sub-directory in Nautlius - everything is there where I expect it to be. The folders/files are not hidden. What is happening here?

At the moment I'm doing:
for i in mdx/[0-9][0-9].png; do cp $i ../../d_s_c/images/mdx ; done
But as well as the directory mdx, I also have other directories called ntt, etc.
How can I say 'For everything in a subdirectory, copy it across to the same subdirectory over at at ../../d_s_c/images'?

I'm trying to write a small script and there's one part of it that makes me sick:
Code:
ifconfig eth$num down
sleep 6
ifconfig eth$num hw ether $mac
ifconfig eth$num up
The problem is that the ethX interface doesn't go down immediately after the first line is executed. So sometimes the change of MAC is called while ethX is up, no matter how big is the sleep time, which results in an error. Is there a way to make this work right?

I want to be able to time how long I spend in front of a terminal. I'm thinking the best way will be to have some sort of timer that starts and stops when the terminal gains/loses focus. And it will have to work with multiple terminals...
I'm using GNOME.

Using xsel I pass a selection into a variable. I then check that the variable includes an embedded newline to be sure that the selection returned by xsel is complete. If the selection content preceding the newline is just a single word, the check fails to detect the newline, thus
Code:
g fnm=`xsel`
g cat <<< "$fnm"

How one could determine (for use in a Bash or Python script) which device (eg /dev/sda1, /dev/hda1... etc) a ramfs was loaded from when booting from a USB drive.
I have a RIPLinux/Tinycore live USB disk that automatically needs to run a script that is stored on the same USB drive but not part of the RIPLinux/Tinycore image. (Please note that I do not want to put this script into the RIPLinux image.) I therefore would like to remix the RIPLinux/Tinycore ISO to automatically run this script once it has started up. After RIP linux has booted I would like to automatically mount the USB drive that RIPLinux/Tinycore was booted from. I need help detecting which device this is.

I have Joomla installed at /var/www/joomla, if I navigate to http://localhost/joomla, I get a 404 error, but if I add index.php, the page loads. What is wrong?? Also I am not able to navigate to the administration part of Joomla for the same reason, typing in index.php doesn't load it in this case. Yes I have verified that all files are present in the directory.

I have a machine (mercury) on which /home/hyperhacker/video is a mounted external hard drive while the rest of /home/hyperhacker is on the internal hard disk. I have a second machine (konata) using autofs to automatically mount mercury:/home/hyperhacker in /mnt/mercury as needed. This works, except /mnt/mercury/video shows up empty.mercury:/etc/exports has: Code: /home/hyperhacker konata(ro,subtree_check)/home/hyperhacker/video konata(ro,subtree_check) and I've tried a few variations in konata: Code: $ cat /etc/auto.master

While saving a file I made a typo and performed the vi command ':w~' instead of ':w!' and I created a root '~' instance in one of my subdirectories. How do I remove this reference without wiping out the entire main /root /~ directory? Do I use unlink()?

I would like to know how can I get permission to subdirectories of a share other than what main share has. I do not want them to have same share I mean for example I share "sharetest" and it has full access for A and B and C groups but "sharetest/foo1" has read only access for A group and "sharetest/foo2" has read only access for B group and "sharetest/foo3" has read only access for all of them.

I have the following command that I run on cygwin:
find /cygdrive/d/tmp/* -maxdepth 0 -mtime -150 -type d | xargs du --max-depth=0 > foldersizesreport.csv
I intended to do the following with this command: for each folder under /d/tmp/ that was modified in last 150 days, check its total size including files within it and report it to file foldersizesreport.csv however that is now not good enough for me, as it turns out inside each
/d/tmp/subfolder1/somefile.properties
/d/tmp/subfolder2/somefile.properties
/d/tmp/subfolder3/somefile.properties
/d/tmp/subfolder4/somefile.properties
so as you see inside each subfolderX there is a file named somefile.properties inside it there is a property SOMEPROPKEY=3808612800100 (among other properties) this is the time in millisecond, i need to change the command so that instead of -mtime -150 it will include in the whole calculation only subfolderX that has a file inside them somefile.properties where the SOMEPROPKEY=3808612800100 is the time in millisecond in future, if the value SOMEPROPKEY=23948948 is in past then dont at all include the folderin the foldersizesreport.csv because its not relevant to me.so the result report should be looking like:
/d/tmp/,subfolder1,<itssizein KB>
/d/tmp/,subfolder2,<itssizein KB>
and if subfolder3 had a SOMEPROPKEY=34243234 (time in ms in past) then it would not be in that csv file.so basically I'm looking for:
find /cygdrive/d/tmp/* -maxdepth 0 -mtime -150 -type d | <only subfolders that have in them property in file SOMEPROPKEY=28374874827 - time in ms in future and not in past | xargs du --max-depth=0 > foldersizesreport.csv

I have a vary unique problem with file and directory ownership. I need to change the ownership of multiple files and directories under a specific subdirectory.Under this directory structure there are files and directories owned my different users and groups. I need to change all files and directories owned by "user1" to "user2". but if any are owned by "user3" I need those left alone.Is there a simple way to do this or will I need to traverse the structure and change things one at a time.

I have the following /etc/fstab:
# /etc/fstab: static file system information.

proc /proc proc defaults 0 0

This is, incidentally, the same message that I see while booting. The error message goes away if I comment out the line in fstab starting with /dev/sdc.

I've installed Squeeze 2.6.32-5-amd64 on my laptop (Alienware M17X R3, Intel i7 Sandybridge, ATI Technologies Inc Broadway [ATI Mobility Radeon HD 6800 Series])The screen is 17", with maximum resolution of 1920 x 1080. After a default install of the operating system, the maximum resolution I can select is 1280 x 1024.My research so far has suggested that I need to edit the /etc/X11/xorg.conf file and provide xorg with the necessary resolution.
Again, by default, the xorg.conf file is not created. This leads me to believe that xorg is scanning my hardware at startup and providing me with whatever it thinks is appropriate. I tried following these instructions to generate an xorg.conf file. This process created an xorg.conf file under /root/.
When I copy this xorg.conf file to /etc/X11, I get a blank (i.e. black) screen. Deleting this file restores the default resolution 1280 x 1024.This system is dual booting with Windows 7. Under windows I am able to get a 1920 x 1080 resolution, so I know my hardware is up to it.At this stage I have yet to install the drivers for the Radeon graphics card.What are my options regarding configuring xorg to give me a higher screen resolution?

OS: Debian 5.0.4
Server: Apache2
I've used mod_rewrite to rewrite my apache2 root (my.server.com/) to point to /var/www/drupal6/ instead of /var/www/. I also have a script installed in my cgi-bin (/usr/lib/cgi-bin) but since the rewrite I can't seem to access it. When I go to my.server.come/cgi-bin/test.pl, I get a page not found from my drupal.
Is there a way I can access my cgi-bin without resorting to accessing my drupal through my.server.com/drupal6/?
Background: I have installed drupal CMS which has a base address of my.server.com/drupal6/ as it resided in /var/www/drupal6/. However I wanted users to be able to access it as my.server.com/ so I added the following into my httpd.conf
Code:
NameVirtualHost *:80
<Directory /var/www/drupal6>
RewriteEngine on
RewriteBase /

To find the appropriate firmware without knowing the make or brand of your wireless chip, you can use the command:
#fw-detect
But apparently debian package do not offer this useful tool, well, certainly for sidux exclusively.
Is there a package of fw-detect eventually?
