-thread-info
Command-thread-info [ thread-id ]
Reports information about either a specific thread, if the thread-id parameter is present, or about all threads. When printing information about all threads, also reports the current thread.
The `info thread' command prints the same information about all threads.
The result is a list of threads. The following attributes are defined for a given thread:
thread name
command, then this name is given. Otherwise, if
gdb can extract the thread name from the target, then that
name is given. If gdb cannot find the thread name, then this
field is omitted.

-thread-list-ids
Command-thread-list-ids
Produces a list of the currently known gdb thread ids. At the end of the list it also prints the total number of such threads.
This command is retained for historical reasons, the
-thread-info
command should be used instead.
Part of `info threads' supplies the same information.
(gdb) -thread-list-ids ^done,thread-ids={thread-id="3",thread-id="2",thread-id="1"}, current-thread-id="1",number-of-threads="3" (gdb)
-thread-select
Command-thread-select threadnum
Make threadnum the current thread. It prints the number of the new current thread, and the topmost frame for that thread.
This command is deprecated in favor of explicitly using the `--thread' option to each command.
The corresponding gdb command is `thread'.
