Read,Write and Execution permissions. r- Read w- Write x- Execution
File permissions in Linux are not represented in binary format, but rather octal format. The first digit represents owner permissions, second digit is group permissions, and the final one is permissions for everyone. Read permissions are assigned a 4, write permissions are assigned a 2, and execute permissions are assigned a 1. A 6 permission allows read and write (4+2).
Create a file and set it's permissions to 222
read, write, execute
You don't say what you want to do with the permissions, but most shells have a 'test' command that can look at various permissions. Look at the 'man' command for the shell you are running in to see what tests are possible on files and directories. You can check to see if the target is a directory, or a file, and whether it has read, write, or execute/search permissions. Again, it varies by the shell environment.
You can use the Server app to set standard permissions-Read & Write, Read Only, Write Only, or None-to control access to a folder and its contents. You can set different permissions for one user (the owner), one group, and all other users who log in. You can also set standard permissions on individual files. Standard permissions are also called POSIX permissions.
I think this is related to permissions given to a file in unix OS. r --> read w --> write e --> execute rw-rw-r-- means first " rw-" for owner read and write permissions " rw- " for group read and write permissions " r--" for others read permissions only I hope this is correct, if any one finds mistake, Please let me know about the mistake... regards, kesavareddy.D
Permissions are allocated based on users and groups, with read, write, and executable privileges being capable of being set.
The group has read and execute permissions. The number is octal; the digits pertain to owner, group and all users respectively. The binary representation in three bits of each digit gives read, write and execute permissions respectively. Thus the middle digit, for group permissions, a 5, is binary 101, indicating read and execute but no write permission.
Read, write, execute and delete.

@Linux : for an example : for a file named " lastlog " Here are its permissions : -rw-r--r-- 1 root root 29492 Dec 1 15:12 lastlog Which means-- here( r )stands for -----Read (w)stands for -----Write and (x)stands for -----Execute Permissions respectively In Detail: User has rw- Permissions(read,write permissions and no execute permission) Group has r-- Permissions and Others have r-- Permissions for the file lastlog* . Extra info : root root ----Means that it is owned by root user(first root) and it belongs to group root (second root). Hope it helped.
