The provided command:

install -d -m 755 /usr/local/sbin

performs the following:

1. install command: This is commonly used in Unix/Linux systems to copy files and set file attributes (like mode/permissions, ownership, etc.) or create directories with specific permissions.

2. -d option: This tells the install command to create a directory instead of installing a file.

3. -m 755 option: This sets the permissions of the created directory to 755. The permissions 755 mean:

   • Owner of the directory has read, write, and execute permissions.
   • Group and others have read and execute permissions.

4. /usr/local/sbin: This is the directory that the command will create.

Summary:

The command creates the /usr/local/sbin directory with owner-read/write/execute and group/others-read/execute permissions (755). If the directory already exists, it does nothing (quietly exits without error).
