General :: Setting Execute Permissions On Second Hard Drive
Apr 4, 2011
I am running Linux Mint on my primary hard drive, and I would like to access some folders I have on my second hard drive, which has Windows XP installed on it. However, whenever I try to use these folders, I am greeted with the error message, "The file is not marked as executable." While I know how to set files as executable whenever I am using folders on my Linux drive, whenever I try to set such permissions on my XP folders, I can't seem to make it work. The files revert to their former status, and I'm told that I don't have permission. Should I set the files as sharable from within XP, so that they aren't marked as read-only? Or is there another solution I've missed?

My mac osx hard drive does not boot anymore and I would like to get my important files off before I reformat the hard drive. I have run into a bit of an obstacle -- there seems to be some permissions setting that are barring me from accessing the files I need to. I can see the Machintosh HD and can access some files. How do I change permissions for the entire drive and all it's directories?

Current when my NTFS external drive is auto mounted, I can't run any executables from it.
If I unmount it and then manually do:
sudo mkdir /media/portable
sudo ntfs-3g /dev/sdc1 /media/portable
it works fine. Is there a way to make the auto-mount have "full" access so I can run applications from it?

You know the great thing about having a debian system is that you have to reinstall so rarely you miss all the new changes that happen in the system until you have to do something like install a new piece of software and realize that fstab has been turned into spaghetti and you no longer have the slightest idea what is going on.I just got a new 1TB USB2 drive to use for backups. I plugged in it and it was recognized fine but it was formatted in NTFS which I didn't particularly want so I reformatted it as ext4FS. It automounts fine but only with all permissions set to root. I tried doing a direct chmod on the drive but that wasn't recognized. Where in the hodgepodge of HAL settings and whatnot do I set it to make the drive user accessible and mount to somewhere other than /media/disk?

I've been installing/tweaking F12, and I've found something that I can't say I've ever seen or expected to find before: the contents of my ~/Documents folder has lost its permissions and ownership info. I restored it from a backup last night/this morning, and I've rebooted a few times since then. Other folders from the backup are OK, just Documents.I don't know what my options are. I could try to blow it away and restore it, but that doesn't answer what caused it. If there's a "relabel" or something, that might help... though I've never had to do it before. Could it be that after these two-and-some-change years, my hard drive is giving out? Good thing I have a recent backup... but it'd be a shame to lose all my work getting F12 to work again.

I'm running Opensuse 11.2 and am using a couple of USB hard drives to store large data. One of these drives is formatted with FAT32 and one with NTFS. When I plug-in a USB device KDE4 shows me a little pop-up asking what I want to do with it, I select to open it in Dolphin which of course automatically mounts it.
My question is what if I want to change some of the mount options - is this possible without reverting to manual mounting? And second question is what system does it use to automount - Fedora, Debian and Ubuntu are all deprecating HAL in favour of pure udev, is this the case in Opensuse too?

I've checked out a subversion project with source c++ files in netbeans 6.8 on Red Hat 5.5. My machine has a dual boot with windows xp and RHEL 5.5 so I checked out the project on a folder called winshare which is a shared drive/partition (E: under xp) allowing both operating systems to access the contents. I've Fedora as virtual machine on xp and wanted to be able to work on the source seamlessly whether using fedora or RHEL.
Problem is that Netbeans is able to build the source just fine but I can't seem to run the generated executable. It has -rw-rw---- permission and the owner is the same user logged in (let's say user1) but no matter what I do, whether I change permissions as user1 or root issuing command chmod 777 -R /dir/where/file/is does not have any effect whatsoever on the executable as well as any .cpp or .h files (nothing that I need exectue permissions on .cpp but just to make a point).

Binary files need only execute permission to execute. No read permission is required. But all executable files must be read by the kernel into main memory before executing. Also script files need both read and execute permissions for executing the file.

setuid bit allows the process to execute the file with the uid of the file. But, what is the purpose of setting setuid without execute bit? The man page tells that if a file is setuid without execute flag, the permission will be displayed as 'S' (capital s) in ls command. Why should anyone set the setuid without execute flag? Does setting setuid without execute flag have any special meaning?

My parents bought a new hard drive for a laptop that I've owned for several years. It's much larger than the current one, so I plan on splitting it up to dual boot it with Ubuntu.I have no problem with partitioning a drive (I always keep a LiveCD handy), but my question is this: how can I go about moving the existing partition to the new drive? This is a laptop, so I can't simply plug the new drive into another slot.
Also, even if I manage to move it, will Windows still work on the new drive in a larger partition? I've had this laptop for quite a while, and I've lost the recovery discs that came with it a long time ago. I also have a lot of software without CDs to reinstall them with. This makes not reinstalling Windows a high priority.

Basically I want a shared hard drive plugged into my wireless router and for the family (me and my girlfriend until the little one grows up) to be able to access common files on the same external without the desktop needing to be on.
How to do this?
Do I just use any external? Does it have to have its own power source if plugged into a router? If I have a networking router how do I access those neat features that seem to be written for WIndows?
There are too many things I like about Ubuntu to go back to Windows, but I would like some tips on having a shared external hard drive via the wireless router instead of dropping money on a new bluetooth enabled router.

Basically I got Windows 7 installed on my laptop and it's been doing nothing but slowing down more and more even though it isn't used for much more than basic internet use and I realized the hard drive was the cause, I did a bunch of stuff to try to fix it that I won't get into here, and in basic I'm to the point I'm just going to reinstall Windows 7, but this time with the help of Ubuntu's partitioning utilities.
I've already had the first ~5GB of the drive overwritten with zero's (thanks to DBAN) and now I'm booted on the Ubuntu LiveCD and trying to learn the command line stuff for formatting a drive. What I want to achieve is use the smallest amount of space possible for the MBR and that's also a point I don't quite understand.
After some research on Google I read that the MBR is on one sector only the very first one, yet the first partition on a hard drive starts anywhere from 63 to 4096. Why are they so far apart? And can I force the partition to be moved closer? I know I know their is pretty much no purpose to this but it bugs me knowing that their might be 31MB (64 512byte sectors minus 1 (MBR) and 64 (beginning of partition)) just going to waste when I could put the NTFS MFT there. Then the second and last part I want to understand is I want to make the NTFS partition have a 512byte allocation unit size and have it lined with the 512sectors on the hard drive so it can have the max performance. Does anyone know how to do this stuff or could find better info than I have on the internet?

On a Powerbook G4, I set hdparm to set the filesystem readahead (-a) to the maximum 2048 on boot. This produces a visible increase in performance... But today the hard drive started acting up - first generating I/O errors when trying to access various system binaries, and the second time bringing the desktop to a standstill and emitting loud clunking noises.In both cases the drive worked normally after a reboot... Even so, these are not what I'd consider good signs. However, the computer was working perfectly up until now, so I'm wondering if my tweaking was responsible. Can overly aggressive filesystem readahead settings damage an IDE hard drive?

I also want to give 705 permissions to all directories and 777 to all files on unzipping?

I have set up freenas with 3 1tb hard drives. I have set up the SMB shares for the drives and can view each shared drive from each of the machines on my network. I can copy files from the hard drives, on the freenas but when I try to copy a file to the Freenas hard drives I get a message that I need permission to do this. I have all my shares set as anonymous how do I change the permissions so that I can save files to the drives.

'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.

i wonder, why nobody has written about it ...
How can i grant permission for files to specific user or specific group ??
Updated:
We have 3 groups: "g12" ("u1" and "u2), "g34" and "g56".
"g12" should only read the file.
"g34" should write and read it.
"g56" should have all permissions (rwx).
And others should not access the file at all.

Sorry if this is the wrong section for this type of question. Anyway, I have two servers running Ubuntu 10.04. Server A has an NFS share that is mounted on server B, and the former has this share set up with specific permissions for a group called netusers. This group basically grants its users read/write permissions, and blocking all of files from anyone who's not part of the group.My question is this: how can I set up the permissions on server B, such that if I was to add a new user on server B, he would have read/write access to the share? I tried adding a counterpart group called netusers with the same permissions on B, but that didn't work.

i borrowed an external hard drive from my friend to back up a load of stuff on my windows partition before reinstalling it. I am doing this through ubuntu. I am trying to zip up folders like My Documents etc and chuck them on the external hard drive but it always comes up with errors to do with read/write permissions. In the permissions tab on the folder properties of the ext hard drive it says I am owner but i have no file access (only folder access is create and delete files). When i try to give myself read/write permission it just goes straight back to nothing when i look at it again.

I'm struggling to understand an aspect of mounting and mountpoints with /etc/fstab. There is a large number of sites and threads that make recommendations using things like uid, gid, umask, and other options. These methods, however, which I've used, are file-system specific, useful only for filesystems such as (V)FAT and NTFS that allow them.My current situation is that I am mounting partition /dev/sdb5 in, let's call it /media/myMount. My goals:Mount this partition automatically upon boot using /etc/fstab...The partition should be fully accessible only to a specific user or group.What I've done is create the mount point in /media:
If user michapma were to carry out the mount, I believe it would work; however, I want the mount to happen automatically during boot. So, how can I achieve my user (or group) permission goals for this and any other such partitions using fstab?The manpage for mount has been helpful, but after reading many tutorials and forum threads, the only way I know how to do it is to have the user do the mounting or rely on the file-system specific options.

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 would like to set both user and group permissions permanently to be 'rwx' (read-write-execute). I would like these rwx settings for all the future files and folders.
I tried umask 002, chmod etc, but they don't set it for future files.

I have a SATA drive that worked fine. Then I installed two more hard drives into my system. When these hard drives are installed, if I try to access the SATA drive in Linux, it will start lightly clicking and then the drive will become unavailable. If I power on the machine without the other two hard drives then it works fine. What could be causing this to happen? I don't think it's heat because the two hard drives are far away from the SATA drive.
