For directories The "sticky bit" also has a different meaning when applied to directories than when applied to files. May 8, I'd like to plug a USB FAT32 formatted memory stick into my Linux laptop and have it mount automatically as it does now but with wide open permissions.
Options This section of fstab contains mount options for partitions. Specify whether the partition should be automatically mounted on boot.
Your Fstab File The fstab file is located at: Which partition number y is it? When the set user ID access mode is set in the owner permissions, and the file is executable, processes which run it are granted access to system resources based on user who owns the file, as opposed to the user who created the process.
Some distros are shipping with ext4 as default. If nouser is specified, only root can mount the filesystem.
Their integrity must be maintained because they can be used to determine when and from where a user or potential intruder has entered your system.
Add this line somewhere in the file: As for "video", this directory is owned by root and the group owner is root. There are quite a few other options that can be placed in this field. Unix separates access control on files and directories according to three characteristics: This means that when, for example, a file is copied to the floppy, the changes are physically written to the floppy at the same time copy command is issued.
An example line in fstab might look like: You may want to give more permission than what's listed, but this should describe what these minimum permissions on directories do: Usually this is the administrator.
One result is that atime is written every time a file is read, which has been heavily criticized for causing performance degradation and increased wear.
This includes permissions on all files and sub directories. You must explicitly mount the filesystem. I have done chmod for a file but I need this for a directory. Visit the following links: Default settings are defined per file system at the file system level. Join our community today! You will see 0,1 or 2 written in this section.
Having a problem logging in? Instead it is written by the system administrator or sometimes by an operating system installation program.
Both directories have the same permissions: How this persistent partition should be formatted? It also prevents someone from creating a hard link to the file.
Are you new to LinuxQuestions.What I want to be able to do, is have create a group, for example called "group1" and set its default permissions to read & write, instead of the usual just read.
So when I add a user into "group1" they automatically have read & write access to all files & directories which is in "group1". Providing educators and students access to the highest quality practices and resources in reading and language arts instruction.
The /etc/fstab entry tells me that the logical partition /dev/sda9 of your disk, which was labeled with a UUID of a1daddba-ceea-b58cdcf during the filesystem format process, will be automatically mounted read/write and contents appear at the /spare directory during system startup.
It would mount, but would not give me read-write permissions. So I could not use it as my solution. Now, you should know that fstab is the preferred method to mount shares on startup.
I think my issue has to do with how the drive is mounted. Here is the fstab entry. The correct way would be to set the read, write, executable flag for tom, and the read executable flag for the group/others. (executable flag = 1) ie.
rw means to mount the device for read and write access. Fstab Mask Permissions. The umask is the default for files and folders, I think its the something like: fstab_perm =!(chmod_perm) (BITWISE NOT) Ramiro Arias You are right George.
No need of a table, just what you said.Download
