I cannot mkdir on an ancillary HDD
[Code].....
I've written a program which creates a directory using the system call mkdir()
How can i execute 'mkdir -v' using this system call? is there another system call to include options?
I just rebuilt my system from cd CentOS5.5
Went to make a dir and got this...
The command took a while to come back. I googled it but nothing came back.
Could this be hadw error? The drive is new. I was able to issue the command again and have it work.
"You'll probably want to operate from inside your home directory. If your user is (for example) username, your home directory will be /home/username/. For the rest of this section we will assume you have downloaded your zip file to /home/username/src. If you do not have a src directory, you can create it with the following "mkdir" (make directory) command:"
Where do the commands go? I cant make it work in terminal. How do I get back to "home" from where i am now? example /home/mydesktop/. I am working in mydesktop. I have downloaded some packages that pkcon search will not find, but when I try to install them using "synaptic" it cant find the packages i dl. So I found this tutorial.
"So, we have our source package in /home/username/src/.
Change to the /home/username/src/ directory with the "cd" (change directory) command like so: cd /home/username/src/
but I dont know where to write the commands.
I was to set up a cronjob that sends its output to a logfile, i want that log file to be unique. the easiest way to set this up would be to make the directory in the script, then output the command to that directory, they call that directory via is full path in cron (because cron only uses full path names.
This does not work
keep in mind the command "/bin/mkdir -p /tmp/pw_log/`date +20%y%m%d_%H%M%S`.log" works fine on the command line - but once I put it in the shell, it does not work.
Code:
This won't work in a script but it WILL work on the commandline...
Here is my output when I try the script:
Code:
Also, what is the at the end of the path in the error?
I'm having a bit of trouble understanding umask and mkdir in C++. In my program, I want to create a directory with the permissions 755.
If I do:-
Code:
The permissions come out all messed up.
But if I do:-
Code:
The permissions are set as expected.
I am having trouble understanding why umask(0); is needed, and what is the 'proper' way to use it so I can make my directory. From what I can understand from the man pages and everything, I need to set the umask in my program to allow it permission to make a directory with those permissions? And I don't get why umask(0); fixes it anyway!
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].
How can we fire a shell command like ls,./a.out automatically in kernel space via a kernel module ? i.e. replacement of system() function of user space into kernel space.We need to develop a kernel module which can fire some shell command let say "firefox [url]" automatically to open google automatically from module.

'the command I would use to change the group permission to write and the user and other to read and execute for the file "generate-report"' Sounds simple enough but I cant get it to work at all, tried doing a search in google and on the forums here to no avail. Is it possible to do in one command or will I need two?
Ive tried:
chmod g+w, uo+rx generate-report
And numerous other variants all with no luck.
What does the mkdir -p flag do? i.e the '-p' part?

View 3 Replies View Relatedim trying to implements mercurial repositories using ssh access.The problem is that if a login via ssh with the user "userA" all file upload vi that user are created with the owner: userA:userA and i need to use the group of the parent directory... is that posible ?For example:
repos ( root:repo)
-> project1 ( root:repoPrj1 )
-> file1 ( userA:usearA ) -> here i want userA:repoPrj1
The setup ( although dont trust anything I say ):
I'm working on an embedded system device using a NFS mounted rootfs ( as shared by my host ) , but I store large video content directly on the device's hdd in /data.
Device's hdd partition /dev/sda3 is ext3 fs mounted at /tmp/mnt/diska3 (rw), then I have a script create dirs like /tmp/mnt/diska3/data and /tmp/mnt/diska3/data/incoming, then symlink :
ln -s /tmp/mnt/diska3/data /data so that the /data appears like any other directory.
I can see /tmp/mnt/diska3/data/incoming. I did chmod -R a+w tmp to rule out permissions.
Running a subsequent script calls mkdir: mkdir -p /data/incoming/gui
BUT fails: mkdir: cannot create directory '/data/': No such file or directory
I have a problem with my external hdd, I mounted it manually and in the mount table it says ive got rw permissions. But when i try to change permissions it says:
chmod: changing permissions of `whatever': read-only filesystem.
This is my mount table:
[root@localhost ExtHDD]# mount
/dev/mapper/VolGroup00-LogVol00 on / type ext3 (rw)
none on /proc type proc (rw)
none on /sys type sysfs (rw)

Im running samba on fedora core 7, im abit new to the server part of fedora, i set up samba and it runs well, only issue i have now is resolving permissions( User Rights)i have a shared folder which has alot of files and many subfolders in it, the files and folders in this shared foldr were copied from our old Novell Server through samba, i need to assign permissions to this folder where by a defined usergroup can have full read and write permissions to all the files and folders and sub-folders in the shared folder. i tried doing it in GUI but i realized there were over 1000 subfolders.is there a command i can run in the Terminal to help me assign the permissions?
View 1 Replies View RelatedInspite of having 755 permissions on the chown command, it seems the command can be executed by the root only. I was under the impression that the 'x' permission for 'others' can give executable rights to the normal user too, which does not seem to be the case here. Just curious to know, if not the file perms itself, what controls the execution of the command?

I am working on a bash script which among its operations creates directories using the mkdir command. However, when the directory already exists mkdir mentions that in the command line output.
Is there any way I can make mkdir silently overwrite any existent directory? (no messages in the output). For the same price, could it be done with other commands such as cp or mv?

Question: How do I set up my 2nd HD with correct permissions? Background: I had previously a dual boot XP+10.04 with a 2nd HD formatted as NTFS. With this I was able to use my rsync and backintime to my 2nd HD with no issue. My new set up is EXT4 on both HD.
(I even tried to reformat my 2nd HD as NTFS, but that didnt fix the issue) I followed [URL] to mount the 2nd HD and get permissions. But now when I run backintime i get this error: [E] Error: rsync: opendir "/home/myhome/.ssh" failed: Permission denied (13) I did my requisite reading for a newbie, and am stuck. I ran backintime as root, and it backed up ok. How do I run my user version of backintime? (i.e. How do I fix the permission issue?)
