@c man begin DESCRIPTION strings
! For each @var{file} given, @sc{gnu} @command{strings} prints the printable
! character sequences that are at least 4 characters long (or the number
! given with the options below) and are followed by an unprintable
! character. By default, it only prints the strings from the initialized
! and loaded sections of object files; for other types of files, it prints
! the strings from the whole file.
! @command{strings} is mainly useful for determining the contents of non-text
! files.

! For each @var{file} given, @sc{gnu} @command{strings} prints the
! printable character sequences that are at least 4 characters long (or
! the number given with the options below) and are followed by an
! unprintable character.
!
! Depending upon how the strings program was configured it will default
! to either displaying all the printable sequences that it can find in
! each file, or only those sequences that are in loadable, initialized
! data sections. If the file type in unrecognizable, or if strings is
! reading from stdin then it will always display all of the printable
! sequences that it can find.
!
! For backwards compatibility any file that occurs after a command line
! option of just @option{-} will also be scanned in full, regardless of

@itemx -
! Scan the whole file, regardless of what sections it contains or
! whether those sections are loaded or initialized. Normally this is
! the default behaviour, but strings can be configured so that the
! @option{-d} is the default instead.
!
! The @option{-} option is position dependent and forces strings to
! perform full scans of any file that is mentioned after the @option{-}
! on the command line, even if the @option{-d} option has been
! specified.
!
! @item -d
! @itemx --data
! Only print strings from initialized, loaded data sections in the
! file. This may reduce the amount of garbage in the output, but it
! also exposes the strings program to any security flaws that may be
! present in the BFD library used to scan and load sections. Strings
! can be configured so that this option is the default behaviour. In
! such cases the @option{-a} option can be used to avoid using the BFD
! library and instead just print all of the strings found in the file.
