#
# Without options, the name and value of each shell variable are displayed in a format that can be reused as input for setting or resetting the currently-set variables.  Read-only variables  cannot  be
#              reset.   In posix mode, only shell variables are listed.  The output is sorted according to the current locale.  When options are specified, they set or unset shell attributes.  Any arguments remain-
#              ing after option processing are treated as values for the positional parameters and are assigned, in order, to $1, $2, ...  $n.  Options, if specified, have the following meanings:
#              -e      Exit immediately if a pipeline (which may consist of a single simple command),  a subshell command enclosed in parentheses, or one of the commands executed as part of a command list  enclosed
#                      by  braces  (see  SHELL GRAMMAR above) exits with a non-zero status.  The shell does not exit if the command that fails is part of the command list immediately following a while or until key-
#                      word, part of the test following the if or elif reserved words, part of any command executed in a && or ││ list except the command following the final && or ││, any command in a pipeline  but
#                      the  last,  or  if the command’s return value is being inverted with !.  A trap on ERR, if set, is executed before the shell exits.  This option applies to the shell environment and each sub-
#                      shell environment separately (see COMMAND EXECUTION ENVIRONMENT above), and may cause subshells to exit before executing all the commands in the subshell.
#              -x      After expanding each simple command, for command, case command, select command, or arithmetic for command, display the expanded value of PS4, followed by the command and  its  expanded  argu-
#                      ments or associated word list.
