setfacl: Modify ACL of a file for user with read and write access.

setfacl

$ setfacl -m u:${username}:rw ${file}

try on your machine

This command sets a specific access control list (ACL) for a file, granting read and write permissions to a specific user.

Here is the breakdown of the command:

setfacl is a command used to manipulate file access control lists on Linux systems.
-m is an option that stands for "modify." It is used to modify an existing ACL or create a new one if it doesn't exist.
u:${username}:rw is the ACL entry being set. The u specifies that this entry is for a user. ${username} should be replaced with the actual username of the user you want to grant permissions to. rw indicates that the permissions being granted are read and write (both).
${file} represents the file for which the ACL is being set. Replace ${file} with the actual path or name of the file you want to modify.

When you execute this command with the appropriate values, it will set the file's ACL to allow the specified user to read and write the file.
