This command is used to modify SELinux boolean values using the semanage tool. Let's break down the command into its components:

• semanage: This is the executable command used to manage SELinux policies.
• boolean: This keyword specifies that we want to manage SELinux boolean values.
• -S ${store}: This option sets the source of the boolean value to be modified. ${store} represents a variable and it would be replaced with the actual source value. For example, it could be system_u, user_u, etc.
• ${select} ${select1}: These are additional options or arguments that help to select the specific boolean to be modified. ${select} and ${select1} are variables to be replaced with the appropriate values. For example, it could be httpd_can_network_connect, samba_export_all_ro, etc.
• -F ${select2}: This option sets the specified boolean value to the new value ${select2}. ${select2} is also a variable that would be replaced with the necessary value. For instance, it could be on or off to enable or disable the boolean.

In summary, the command semanage boolean -S ${store} ${select} ${select1} -F ${select2} is used to modify a specific SELinux boolean value by specifying the source, the boolean name, and the new value.
