$- is used to show current shell options (in Bash, Korn and others)... These can be options passed during the shells invocation (i.e. when the shell is first started), or set whilst the shell is running with the "set" command. For example....

$ echo $-
himBH
$ set -x
$ echo $-
himxBH
$ set +x
$ echo $-
himBH
$ bash -r # start another shell with -r set
$ echo $-
himrBH
$ exit
$ echo $-
himBH

Read the manual page for the shell you're using and take a look at the "set" section and also the invocation options section.

I check the value of $- in my .kshrc file to make sure that it is executed for interactive shells only.

Cheers

scmp_sys_resolver(1)					     libseccomp Documentation					      scmp_sys_resolver(1)

NAME

       scmp_sys_resolver - Resolve system calls

SYNOPSIS

       scmp_sys_resolver [-h] [-a ARCH ] [-t] SYSCALL_NAME | SYSCALL_NUMBER

DESCRIPTION

       This command resolves both system call names and numbers with respect to the given architecture supplied in the optional ARCH argument.	If
       the architecture is not supplied on the command line then the native architecture is used.  If the "-t" argument is specified along with  a
       system  call  name,  then the system call will be translated as necessary for the given architecture.  The "-t" argument has no effect if a
       system call number is specified.

       In some combinations of architecture and system call, a negative system call number will be displayed.  A negative system call number indi-
       cates  that  the  system  call  is not defined for the given architecture and is treated in a special manner by libseccomp depending on the
       operation.

       -a ARCH
	      The architecture to use for resolving the system call.  Valid ARCH values are "x86", "x86_64", "x32", and "arm".

       -t     If neccessary, translate the system call name to the proper system call number, even if the system  call	name  is  different,  e.g.
	      socket(2) on x86.

       -h     A simple one-line usage display.

EXIT STATUS

       Returns zero on success, errno values on failure.

NOTES

       The libseccomp project site, with more information and the source code repository, can be found at http://libseccomp.sf.net.  This tool, as
       well as the libseccomp library, is currently under development, please report any bugs at the project site or directly to the author.
