def openbmctool_execute_command(command_string,
*args,
**kwargs):
r"""
Run the command string as an argument to the openbmctool.py program and
return the stdout and the return code.
This function provides several benefits versus calling shell_cmd directly:
- This function will obtain the global values for OPENBMC_HOST,
OPENBMC_USERNAME, etc.
- This function will compose the openbmctool.py command string which
includes the caller's command_string.
- The openbmctool.py produces additional text that clutters the output.
This function will remove such text. Example:
Attempting login...
<actual output>
User root has been logged out
NOTE: If you have pipe symbols in your command_string, they must be
surrounded by a single space on each side (see example below).
Example code:
${rc} ${output}= Openbmctool Execute Command fru status | head -n 2
Example output:
#(CDT) 2018/09/19 15:16:58 - Issuing: set -o pipefail ; openbmctool.py -H hostname -U root -P ********
... fru status | tail -n +1 | egrep -v 'Attempting login|User [^ ]+ hasbeen logged out' | head -n 2
Component | Is a FRU | Present | Functional | Has Logs
cpu0 | Yes | Yes | Yes | No
Description of arguments:
command_string The command string to be passed to the
openbmctool.py program.
All remaining arguments are passed directly to shell_cmd. See the
shell_cmd prolog for details on allowable arguments. The caller may code
them directly as in this example:
openbmctool_execute_command("my command", quiet=1, max_attempts=2).
Python will do the work of putting these values into args/kwargs.
