7.2.1 Choosing your Editor

You can customize No value for GDBN to use any editor you want (4). By default, it is ‘/bin/ex’, but you can change this by setting the environment variable EDITOR before using No value for GDBN. For example, to configure No value for GDBN to use the vi editor, you could use these commands with the sh shell:

 
EDITOR=/usr/bin/vi
export EDITOR
gdb …

or in the csh shell,

 
setenv EDITOR /usr/bin/vi
gdb …
