General :: File Permissions In Every Element Of Path Or Just Last One?
Dec 17, 2010
Kernel 2.6.21.5, slackware 12.0 For a given app run by me as user john to be able to create a file in /foo1/foo2/, what do I need? (a) john to have write permissions in /foo1/? (b) john to have write permissions in /foo1/foo2/? (c) john to have write permissions in both /foo1/ and /foo1/foo2/? Any hint will be welcome. Note: No. It's not homework. KTorrent complains when trying to create the files being downloaded, saying 'permission denied'. But I think he is being run by another user. I can explain in a different thread.
I'm using my Linux (SLES 10) server as a File Server at this point. I need to set File Permissions to nested folders differently to different groups. For example:
homesharedengineering* should be read only for groupA homesharedengineeringadmin should be read & write for groupB Plus read only for groupA homesharedengineeringautocad should be read & write for groupC Plus read only for groupA
I've been using Webmin and Putty to set permissions but Putty only allows me the Default Group, it won't allow me to set several groups on the same directory. Webmin seems to allow me to add multiple groups (Webmin --> Others --> File Manager --> Info & ACL tab will provide extended abilities) but when I add multiple groups, they don't seem to take effect? I'm wondering if my setup at the 'Share' level or at the hierarchy of my folder structure (unix based) needs to be set specifically?
I have a doubt, i have a file which contains around 3000 elements, now i want to search for an element in that file.what will be the Efficient way of searching ? without consuming much memory and time..
1) is this efficient if i take all the 3000 elements from file to a list or array and sort them and search ? 2) or is it efficient to search directly inside the file ?? Can anyone please suggest some algorithms for an efficient way to search in this case ?I am using C for coding..
I'm taking here about tins of directories, thousands of files. I'm looking to find a command that makes me able to move the results above to another path, and to create that path once it doesn't exist like below:
I've been looking around the net for executing a shell script. My basic understanding is that after setting executable permissions and providing a path (#!/bin/sh) in the first line of the script, I can type ./myscript to execute instead of sh myscript. This is not working for me. I can run "sh myscript" but not "./myscript" even though I know for sure I have across the board execute permission and my sh path is correct. I'm working on a redhat linux station.
I had a situation in which the the path of the file to be copied is written in other file and I had to copy it using shell script..I can use cp $(cat /home/robert/location.txt) /media/sda1 on normal linux shell...But I am using buildroot script where $(cat /home/robert/location.txt) evaluate to nothing..is just blank..
I have an ntfs partition that I wish to access as a normal user(non-root). For this I did the following. As root I created a folder /windows and did a chmod 777 -R on /windows. Then I added the following line to /etc/fstab
Now, the partition is mounted alright but the problem is that when any other user (non-root) creates a files in /windows (say by executing touch newfile) the newly created file has the owner and group set as root. The non-root user can create the file and he can also delete the file, however, he cannot change the permissions of the file and also the owner:group is always set as root:root. How do I get across this problem, i.e. how do I mount a partition, so that a non-root user can also change the permissions and ownerships of the files he creates.
i can download but i cant run anything because there is no ar file path for ark. please dont tell me to download something to get the ar file path because if i download it i can't open it
The problem is I can't use $0 as reference because the script is only sourced not executed. I also don't want to hardcode the path because the location might change and there will be more copies. Is there an easy way to create this information from within the the sourced bashrc file? I use Gnu bash 2.05b on Suse Linux 9.
I have installed a software and set the variables in the .bashrc file to avoid setting them everytime I would like to run te software. Now I have installed a new software and would like to do the same thing in the .bashrc file.How can I add the path to the new software directory without affecting the first software path.
Finally I managed to install my printer/scanner drivers.The last thing I need to do is to add the following two lines to 40-libsane.rules (which is a read only file):# Brother scanners ATTRS{idVendor}=="04f9", ENV{libsane_matched}="yes".How can I change permissions for this file or add these lines without changing permissions?
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.
I have an array ch and I want to increment each element in my array for the following if statement. I'm not sure I have the right array increment syntax but I have tried it in different ways ant it doesn't seem to work.
I tried ch[$1]++, ch[$1]+1, ch[$1++], ch[$1]+=1, ch[$1]=ch[$1]+1 none of these seem to work. # while loop reading from read.txt for check list 1 - 15 for i in `seq 15` do a=`grep "${cl[$i]}" $file` status=$? if [[ $status = 0 ]]; then echo -n -e "1 " let ch[$i+1] let k++ else echo -n -e "0 " fi done for l in `seq 20` do echo -n -e "${ch[$l]} " done
I am unable to create either a file or a directory in a specified path in Linux. I am getting the error "No space left on device". I have checked with df -k and df -i. Free disk space is 28 % and free inodes are 28 %. What else could be the reason?
I am reading about jiffies in linux kernel. In one of the related example in the book Linux Device Driver, the author use head -8 /proc/currentime to print out some time information.
However this file is not present in my linux installation (kernel: 2.6.32-131.6.1.el6.x86_64). Why is it the case? Is it because the file path is no longer valid, or it is a distribution feature thing? It is not present in OSX too. What would be an equivalent in OSX?
I am total new to linux as I worked mostly on RTOS (symbian). My problem is, I need to find the file IOSTREAM.H and I am following commands below: 1) cd / 2) find . iostream.h ( finds the file / directory from the current path) It shows No such File or Directory
trying to write my thesis in Lyx 1.6. It works fine on my windows laptop at home but Not on my work computer. The problem is, when i try to view it in pdflatex it comes with with: Lyx: file name error The directory path to the document cannot contain spaces
I need to replace a string in a file(startup.sh) using a script(parser.sh). After running parser.sh startup.sh should be filled with nfs path like /home/vimal etc but im getting error since path contains /. how to remove this.
I have a program that takes a relative path as input appends it to a some path string to get the actual path.
Now all I can input is the relative path. So if I want to go one level above my input will be ../mypath.
If I know the depth of the path used internally, I can use .. as many times to go to the root directory and then give the absolute path. But suppose I do not know the depth of the directory, can I construct a relative path string such that it considers it as a relative path. One way could be to have enough .. in the path string so that I can force an absolute path for some maximum depth of path.
Is there some path string syntax that I am not aware of but can achieve this?
Experimenting with shell variables, accidentally deleted the path variable how could I return to the original path value. What kinds of problems will I have if I don't have a path variable.
I have a path c:windowsackup I need this string to be changed into /windows/back/up I used the command -bash-3.00$ echo windackup | sed 's/\//g' but the output is windbackup
prefix=user@my-server: find . -depth -type d -name .git -printf '%h�' | while read -d "" path ; do ( cd "$path" || exit $?
[code]....
How shall i go about changing the absolute path to relative path, so that /home/git/mirror/android/adb/ndk.git gets converted to /mirror/android/adb/ndk.git //echo <command> "$prefix$PWD.git" ?? - anything for relative path?
