To edit the lines in a source file, use the edit command.
The editing program of your choice
is invoked with the current line set to
the active line in the program.
Alternatively, there are several ways to specify what part of the file you
want to print if you want to see other parts of the program:
edit locationlocation. Editing starts at that location, e.g., at the specified source line of the specified file. See Specify Location, for all the possible forms of the location argument; here are the forms of the edit command most commonly used:edit numbernumber as the active line number.edit functionfunction at the beginning of its definition.
You can customize GDB to use any editor you want
10.
By default, it is /bin/ex, but you can change this
by setting the environment variable EDITOR before using
GDB. For example, to configure GDB 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 …
The only restriction is that your editor (say ex), recognizes the
following command-line syntax:
ex +number file
The optional numeric value +number specifies the number of the line in
the file where to start editing.
