+user ID specified by the user operand. The user operand is a decimal
+integer user ID.
+.IP "ln source_file target_file"
+The ln and symlink commands create a symbolic link at the target_file location
+pointing to the source_file location.
+.IP "mkdir directory_name"
+The mkdir command creates the directory named by the directory_name operand.
+.IP "pwd"
+The pwd command returns the absolute pathname of the current working directory.
