Debugging with GDB

21.4 TUI specific commands

The TUI has specific commands to control the text windows. These commands are always available, that is they do not depend on the current terminal mode in which GDB runs. When GDB is in the standard mode, using these commands will automatically switch in the TUI mode.

info win

List and give the size of all displayed windows.

layout next

Display the next layout.

layout prev

Display the previous layout.

layout src

Display the source window only.

layout asm

Display the assembly window only.

layout split

Display the source and assembly window.

layout regs

Display the register window together with the source or assembly window.

focus next | prev | src | asm | regs | split

Set the focus to the named window. This command allows to change the active window so that scrolling keys can be affected to another window.

refresh

Refresh the screen. This is similar to using C-L key.

update

Update the source window and the current execution point.

winheight name +count

winheight name -count

Change the height of the window name by count lines. Positive counts increase the height, while negative counts decrease it.
