r"""
Run the given command string in a shell and return a tuple consisting of
the shell return code and the output.
Description of argument(s):
command_string The command string to be run in a shell
(e.g. "ls /tmp").
quiet If set to 0, this function will print
"Issuing: <cmd string>" to stdout. When
the quiet argument is set to None, this
function will assign a default value by
searching upward in the stack for the
quiet variable value. If no such value is
found, quiet is set to 0.
print_output If this is set, this function will print
the stdout/stderr generated by the shell
command to stdout.
show_err If show_err is set, this function will
print a standardized error report if the
shell command fails (i.e. if the shell
command returns a shell_rc that is not in
allowed_shell_rcs). Note: Error text is
only printed if ALL attempts to run the
command_string fail. In other words, if
the command execution is ultimately
successful, initial failures are hidden.
test_mode If test_mode is set, this function will
not actually run the command. If
print_output is also set, this function
will print "(test_mode) Issuing: <cmd
string>" to stdout. A caller should call
shell_cmd directly if they wish to have
the command string run unconditionally.
They should call the t_shell_cmd wrapper
(defined below) if they wish to run the
command string only if the prevailing
test_mode variable is set to 0.
time_out A time-out value expressed in seconds. If
the command string has not finished
executing within <time_out> seconds, it
will be halted and counted as an error.
max_attempts The max number of attempts that should be
made to run the command string.
retry_sleep_time The number of seconds to sleep between
attempts.
allowed_shell_rcs A list of integers indicating which
shell_rc values are not to be considered
errors.
ignore_err Ignore error means that a failure
encountered by running the command string
will not be raised as a python exception.
When the ignore_err argument is set to
None, this function will assign a default
value by searching upward in the stack for
the ignore_err variable value. If no such
value is found, ignore_err is set to 1.
return_stderr If return_stderr is set, this function
will process the stdout and stderr streams
from the shell command separately. In
such a case, the tuple returned by this
function will consist of three values
rather than just two: rc, stdout, stderr.
fork Run the command string asynchronously
(i.e. don't wait for status of the child
process and don't try to get
stdout/stderr).
