chmod: Recursively give [a]ll users [r]ead permissions to files and e[X]ecute permissions to sub-directories within a directory.
$ chmod -R a+rX ${path-to-directory}
try on your machine
The command "chmod -R a+rX ${path-to-directory}" is used to modify the permissions of files and directories in a specific directory.
Here is the breakdown of each component:
- "chmod" is a command-line utility in Unix-like operating systems that is used to change file permissions.
- "-R" is an option that stands for "recursive" and is used to modify permissions for all files and directories inside the specified directory, including subdirectories and their contents.
- "a+rX" is the permission argument. It consists of two parts:
- "a+r" means to add read (r) permission for all users (owner, group, and others).
- "X" means to add execute (x) permission for directories and files that already have execute permission for some user. It does not add execute permission if it is not already set.
- "${path-to-directory}" is the placeholder for the actual path to the directory you want to modify the permissions for. You need to replace it with the actual path like "/path/to/directory".
Overall, this command will recursively add read permission for all users and execute permission for files and directories that already have execute permission in the specified directory and its subdirectories.
