When I installed a new copy of my distro on another partition, in order to preserve all the settings from my old my user account, I made a user account with the same name on the new installation, and then copied my old user account's files (in their entirety) to the new user account, overwriting it. I did the copying from the root account (where else? I assume the new user account can't overwrite itself while it's open), and root became the owner of everything I copied, making it impossible to open the new user account. So I then chowned the new user account's folder to myself. I still can't get in, because apparently, chown only chowned the top folder, leaving all subdirectories owned by root. How do I make chown include all subdirectories? I scanned the man page, but didn't see a parameter.
What is the difference between /usr/local/include and /usr/include? When I compile my program, is both /usr/local/include and /usr/include avaliable? Can I copy a file from /usr/local/include to /usr/include?
I just downloaded the SDL source code. i did compile and make of this code.then i did make install. but i didnt see the files of SDL.h and lib.SDL.*** in /usr/include/ but later i found out that these files are placed in /usr/local/include and /usr/local/lib. how can i specifically install libraries on /usr/include and /usr/lib
My home/container has me as the owner but the contents all belong to root...I've tried >chown cbjhawks /home/cbjhawks but that didn't change anything. Should it be >chown -R cbjhawks /home/cbjhawks? Or what is the proper command for doing this...
I've just installed Ubuntu 10.10 AMD-64 and mounted several partitions into /mnt/ directory. Now I want to be able to perform operations on those partitions without limitations. I'm trying to change the owner and group but it doesn't work. I'm typing sudo chown username filename to perform the operations.
I looked through google but can't find an answer for this..... say I have a directory called "files"; this directory contains several other directories..... what I wanna do is delete ALL the files within the subdirectories, but NOT delete the subdirectory. Can this be done easily without having to run a command for each subdirectory?
vsftpd 2.3.2-3After user uploaded a file it has -rw-------(0600) permissions. Of course user can change permissions manualy to any he likeBut how to set for example 0700 by default?
I have a samba share that I mount locally at boot through fstab. The share is writable and if I access the share directly, say with konqueror and smb (smb://hostname/sharename) then I can do anything I want (create, write, delete, edit, files/directories). I have a mount point on my local machine
Code:
/shares/mp3
and I (username dtest) was unable to do anything except read files and create directories trying to do them to the local mountpoint except as root. I figured it would be a matter of
Code:
chown -R dtest /shares/mp3
but I was unable to do that even as root, I kept getting permission denied. When I did
Code:
ls -alt /shares/ it told me the owner was 1000 and the group was root. Dtest was already a member of the root group and I was able to
Code:
chmod -R 774
as root but I still couldn't do anything except read and create directories directly via the mountpoint. Ultimately I solved this by changing the uid of user dtest via kuser and then just chowning my home directory back to dtest. It seems like as root I should be able to change the owner of the directory. I know it's because this is a samba share, but it doesn't make any sense why root couldn't just chown it. Is there another way to change the owner of a directory, or is this set by the machine hosting the samba share?
I am desperately trying to recover two folders from a Freecom FSG 3 NAS. As far as I am aware it is running Linux 2.6 based on Snapgear. After working through the hardwares' recovery procedure a number of times, the state of the device appears to get worse and worse. So I have attempted to rescue the files by using a program called Putty to access the device over SSH.When I access the device using Putty I login as admin. The folders I need to recover are located in the home folder. Listing the contents of the directory I get...
Performing commands in multiple subdirectories simultaneously. I'd like to run a program I've copied into every subdirectory which takes *.in files in the current directory as input files. I can find the program, but how do I tell it to run when I've found it?
i'd like to execute in several subdirectories that all have the same name, but I don't want to have to change into each subdirectory (there are hundreds) to execute the script. All the subdirectories have the same name ("final_alignments"), but are located in parent directories with different names. All these parent directories are in the same "super parent" directory. I've tried to do this using "for/do" and "find" but no luck so far.
1. How can you find all first level subdirectories under the current directory? 2. How will you show the last 100 lines of the file "foo.log"? 3. How will you Stream the contents of a the log file "foo.log" as it gets written to? 4. How can you grep for a pattern on a gzip'ed file? e.g., find "foo" in bar.gz 5. Find all lines in the file "foo" which DON'T have the pattern "bar" 6. Your web server is running very slowly. If you can login to the server, what command will you run to find out cpu and memory use? 7. Extract the file foo which is a part of the tar'ed, gzip'ed file bar.tar.gz 8. You attach a usb disk to your linux desktop, but it does not show up. How can you get more information about the error? 9. What is the secure way to login to remote systems? 10. What is the difference between TELNET and SSH? 11. Given a file 'a' with the following permissions -rwxrwxrwx 1 rohit rohit 0 2011-01-24 13:30 a Change its permissions such that it is only readable and writable by its owner, not accessible by anybody else in the group and only executable by the world 12.

I have .jpg files in many subdirectories from where I need to copy all the images from all the sub directories and paste them to a specific directory.I have used `cp -rf *.jpg media/sik/` which only copies the .jpg files of the directory in which I was working.
I am a noob and I am trying to display a count of the number of subdirectories in a directory. I have been able to use find -type d to list directories and subdirs but I want a numerical value of dirs and subdirs. I know ls -l gives a count but when I try ls -l -d all it shows is "." I also have tried a combination with the -R option but nothing seems to be working for me.Please forgive my ignorance but I am working on a script for class and this is the first step.
I'm able to use the following to remove the target directory and recursively all of its subdirectories and contents. find '/target/directory/' -type d -name '*' -print0 | xargs -0 rm -rf
However, I do not want the target directory to be removed. How can I remove just the files in the target, the subdirectories, and their contents?
I need to give a user write access to /var/www and its subdirectories. The current directory permissions are as follows:rwx r-x r-x root root
I added the user to the root group but that didn't seem to help.I read I could chmod -R to change the access to write for the www directory and subdirectories but I don't want to change things and mess up the website. How can I give the user access to write to the www directory and subdirectories without messing anything up? Would changing the www directory group owner to his group cause an issue anywhere?
I'm looking to get a shell script to loop through a number of directories and subdirectories,looking for files that contain a particular substring, and renaming the file by replacing the search string with a different substring. For example if you had a directory full of folders that contained digital photos (along with various other files which would need to remain unaffected), and the intent was to remove the "DSC_" prefix from several thousand files buried within. I've whipped up a rather long-winded solution that works well for this purpose but chokes on directory names with spaces. I am reasonably sure there's a 2 or 3-liner that would accomplish this exact same task.
function investigate { path=$1 for file in `ls $1` #for file in *
I am trying to write a very simple script that will go to every subdirectory of a single directory and run a command (lets call it make_ndx).I know I can write this the long way with in a text document with something like:
cd /"the directory"/"the 1st subdirectory" make_ndx cd .. cd "the 2nd subdirectory" cd ..
Alternatively, I also tried: for i in 'find /path/somemorepath -type d -mindepth 1'; do cd $i; make_ndx -f *.gro; done which returns me with the error cd: find: no such file or directory. But if I run the find command by itself to test if I am calling the right directories, it gives me the exactly the output I am looking for. Any ideas? Should I just write the find results to a file and loop through the contents of the file (which seems a little bit like overkill) or am I just making a simple typographical mistake and I am just not seeing it?
I need to copy all subdirectories and files from one directory to another ever 5 minutes or so, with the old data automatically being overwritten with the new data. I'd also like this to run at startup. Is there any way this can be done? If so, what program would I need to schedule the automation and what is the command line I would need.
I am trying to set the default printer on a machine running xubuntu from the command line. It looks like I need: lpoptions -d "printer_name" but I do not know the name of the printer. How can I find this information?
