+Set/show the directory where index files will be saved.
+
+The default value for this directory depends on the host platform. On
+most systems, the index is cached in the @file{gdb} subdirectory of
+the directory pointed to by the @env{XDG_CACHE_HOME} environment
+variable, if it is defined, else in the @file{.cache/gdb} subdirectory
+of your home directory. However, on some systems, the default may
+differ according to local convention.
There is no limit on the disk space used by index cache. It is perfectly safe
to delete the content of that directory to free up disk space.
Show the name of executable of the process. This command is supported

+Show the file descriptors open by the process. For each open file
+descriptor, @value{GDBN} shows its number, type (file, directory,
+character device, socket), file pointer offset, and the name of the
+resource open on the descriptor. The resource name can be a file name
+(for files, directories, and devices) or a protocol followed by socket
+address (for network connections). This command is supported on
+FreeBSD.
