Bash chmod Command - Change File Permissions

The chmod command is used to change the file permissions in Unix-like operating systems.

It allows you to set who can read, write, or execute a file.

The chmod command has several options to customize its behavior:

• -R : Change files and directories recursively.
• -v : Output a diagnostic for every file processed.

The -R option allows you to change permissions for files and directories recursively.

This is useful when you want to apply the same permissions to all files and subdirectories within a directory.

The -v option provides verbose output, showing a diagnostic message for each file processed by the command.

The chmod command is commonly used to:

• Set executable permissions for scripts.
• Restrict access to sensitive files.
• Ensure that files have the correct permissions for sharing.
