Overview On Linux and other Unix -like operating systemsthere is a set of rules for each file which defines who can access that file, and how they can access it.
How would I do the others using this method? Would these the same commands for fedora? Linux ignores the sticky bit for files, but other OSes honor it.
And yes, the commands work an any Unixy OS. If you would find it inconvenient to have to reinstall your system or retrieve data from a live session, make sure you experiment with permissions and ownership safely.
While you're learning your way around the filesystem and basic commands, you should avoid running chmod and chown with sudo or in a root shell.
That way, a permission error will let you know that you might be doing something risky and you should check the command again.
We change file permissions with chmod. This command has a recursive flag -R. This flag is often used unnecessarily, and it is rarely useful, because we don't usually want directories to have the same permissions as the files inside them.
Directories need execute permission to be entered, so aren't useful without it, while files only need execute permission if they are programs. Without the -R flag, chmod can do only limited and repairable damage, but with -R you can make a terrible mess of your system in a single command.
If you are using -R, consider whether you really need it, and check the file path for typos. The mode you have been asked to give the file is a common one -rwxr-xr-x The leading dash indicates that this is a regular file.
The x bits in three places indicate that it needs to be executable by any user. So, this mode is appropriate for programs that anyone can execute. It's important for security that only the owner, root, can write to modify these files, so the programs you run can't be accidentally or otherwise changed by users without root privileges.
As pointed out in George Udosen's answer the permission bits are set separately for user the owner of the filegroup, and others. This is explained, for example, in our tag wiki for chmod and in many other places on the internet, and even on your system; you can read about it by running man chmod.
You have been asked to make the file readable, writeable and executable by its owner, and readable and writeable for its group and others. You can see the owner and group of a file by running ls -ld file the -d is only necessary if it's a directory; without that flag, ls shows the content of the directory rather than the directory itself or if you want less irrelevant information, use stat: If it's in the current directory, its name is sufficient, but you can give a path for files elsewhere: This provides a very useful reference if you ever forget what permission bits a particular octal number represents to chmod, though vidarlo's answer provides a nice way to recall them.// Depending on whether the characteristic has the WRITE REQUEST property or not, we will either send it as it is (hoping the long write is implemented), // or divide it into up to .
