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).

Run the given command in an SSH session and return the stdout, stderr and

If there is no open SSH connection, this function will connect and login.
Likewise, if the caller has not yet logged in to the connection, this
function will do the login.
NOTE: There is special handling when open_connection_args['alias'] equals

Description of arguments:
cmd_buf The command string to be run in an SSH
session.
open_connection_args A dictionary of arg names and values which
are legal to pass to the SSHLibrary
open_connection function as parms/args.
At a minimum, this should contain a 'host'
entry.
login_args A dictionary containing the key/value
pairs which are acceptable to the
SSHLibrary login function as parms/args.
At a minimum, this should contain a
'username' and a 'password' entry.
print_out If this is set, this function will print
the stdout/stderr generated by the shell
command.
print_err If show_err is set, this function will
print a standardized error report if the
shell command returns non-zero.
ignore_err Indicates that errors encountered on the
sshlib.execute_command are to be ignored.
fork Indicates that sshlib.start is to be used
rather than sshlib.execute_command.
quiet Indicates whether this function should run
the pissuing() function which prints an
"Issuing: <cmd string>" to stdout. This
defaults to the global quiet value.
test_mode If test_mode is set, this function will
not actually run the command. This
defaults to the global test_mode value.
