What does the chmod command do in Linux?

In Linux, the chmod command allows you to change the permissions of a file or directory. The permissions are a set of rules that determine who can access the file or directory and what they can do with it. There are three types of permissions: read (R), write (W), and execute (X). The most common permission is read, which means that people can view the contents of the file but cannot modify it. The next most common permission is write, which means that people can modify the contents of the file but not view it. The least common permission is execute, which means that people can run programs from the file.

How can permissions be set so that only certain users haveaccess to execute, read, or write specific files ?

In Linux, permissions can be set so that only certain users have access to execute, read, or write specific files. To change the permissions on a file, use the chmod command. The following table lists the different types of permissions and their corresponding values:

Permission Type Value

Execute 0x00000001

Read 0x00000002

Write 0x00000004

Group permission: This type of permission allows a user to execute a file as if it were part of their group membership. For example, if you are logged in as root and you want to make sure that all users in your office have access to open the file test.txt, you would use the chmod command with the g+ option (group plus). This would give everyone in your office the ability to execute test.txt as if it were part of their regular shell commands. If you wanted just one user in your office to be able to open test.txt but not be able to modify it, you would use the u+ option (user plus). You can also combine these options together; for example, if you wanted someone in your office to be able to open test.txt but not be ableto modify it, you would use chmod u+g+w test.txt . Note: In order for group permission settings on files and directories to take effect, they must first be created using either mkdir -p or touch -t "groupname" . Files and directories without this special treatment will not have any group permissions applied when they are accessed by members of that group name . For more information about groups , see Section Access control list (ACL): ACLs allow administrators or system administrators greater control over who has access rights than what is given by simple mode permissions alone. ACLs are made up of three parts: source IP address(es), destination IP address(es), and action(s). When specifying an ACL for a file or directory using the chmod command, include at least one source IP address and one destination IP address; otherwise no changes will occur . Source IP addresses refer to computers that attempted or succeeded in accessing the file/directory while destination IP addresses refer either explicitly assigned localhost addresses or any other host listed within /etc/hosts on which an application running under UNIX trusts its network connections originate from (.e., 12

  1. 1 , “Groups” .
  2. *.*.*) ). Actions taken by systems with access rights granted through an ACL depend on whether they match one of two predefined sets : deny means do nothing ; allow means perform whatever action is specified after Allow followed by one space character then another allowed action such as read , write , append , etcetera .
