Choosing
files
When GDB starts, it reads
any arguments other than options as specifying an executable file and core
file (or process ID). This is the same as if the arguments were specified
by the -se
and -c
options respectively. (GDB reads the first argument that does not have
an associated option flag as equivalent to the -se
option followed by that argument; and the second argument that does not
have an associated option flag, if any, as equivalent to the -c
option followed by that argument.)
Many options have both long
and short forms; both are shown in the following list. GDB also recognizes
the long forms if you truncate them, so long as enough of the option is
present to be unambiguous. (If you prefer, you can flag option arguments
with --
rather than -,
though we illustrate the more usual convention.)
-symbols file
-s file
Read symbol table from file,
file.
-exec file
-e file
Use file, file,
as the executable file to execute when appropriate, and for examining pure
data in conjunction with a core dump.
