## sdb

    sdb [options] [objfile [corefile [dir_list]]]

A C and FORTRAN symbolic debugging program used to look at "core" files resulting from aborted programs. `objfile` contains an executable program, and `corefile` contains the core image produced when `objfile` was executed. a.out is the default `objfile`. core is the default `corefile`. The `dir_list` argument specifies the source directory for the files compiled to create `objfile`. See Section 20 for more information on sdb.

### Options

-e

  Ignore symbolic data; treat addresses as file offsets.

-s `n`

  Don't stop processes that receive signal number `n`. See the signal system call for values of `n`. -s may be used more than once.

-V

  Print version information (exit if no `objfile` is given).

-w

  Make `objfile` and `corefile` writable.

-W

  Suppress warning messages about older files.
