# Module: rmcondition #
# #
# Purpose: #
# rmcondition - remove a condition. #
# #
# Syntax: #
# rmcondition [-h] [-f] [-q] [-TV] Condition[:Node_name] #
# #
# Flags: #
# -h help - writes this command's usage statement to stdout #
# -f forces the condition to be removed even if it is linked #
# to responses. The links with the response are removed as #
# well as the condition, but the responses are not removed.#
# -q do not return an error when the Condition does not exist #
# -T Trace. IBM Support Center use only. #
# -V Verbose. #
# #
# Operands: #
# Condition The name of a condition to be removed. Node_name #
# specifies where the condition is defined. #
# #
# Description: #
# The rmcondition command removes the condition specified by the #
# condition operand. The condition must already exist to be #
# removed. When the condition must be removed even if it has #
# linked responses, use the -f flag to force the condition and #
# the links with the responses to be removed. If the -f flag is #
# not specified and links with responses exist, the condition is #
# not removed. Responses are not removed by this command. #
# #
# Exit Values: #
# 0 ERRM_CLI_SUCCESS Command completed successfully. #
# 1 ERRM_CLI_RMC_ERROR Command terminated due to an underlying #
# RMC error. #
# 2 ERRM_CLI_ERROR Command terminated due to an underlying #
# error in the command script. #
# 3 ERRM_CLI_BAD_FLAG Command terminated due to user #
# specifying an invalid flag. #
# 4 ERRM_CLI_BAD_OPERAND Command terminated due to user #
# specifying a bad operand. #
# 5 ERRM_CLI_USER_ERROR Command terminated due to a user error. #
# For example specifying a name that #
# already exists. #
# #
# Examples: #
# 1. Remove the condition named "JFS space used up": #
# rmcondition "JFS space used up" #
# 2. Remove the condition named "JFS space used up" even if the #
# condition is linked with responses: #
# rmcondition -f "JFS space used up" #
# #
# Man Page: #
# For the most current detailed description of this command see #
# the rmcondition man page in /opt/rsct/man. #

# General Program Flow/Logic: #
# #
# 1. Parse command line flags and operands, determine which flavor #
# of this command we are actually invoking. #
# This command allows a user to remove conditions #
# 2. Print usage if -h specified #
# 3. Make sure one and only one condition is specified #
# 4. Make sure the condition exists. #
# 5. If it doesn't exist and -q was specified, exit. #
# 6. If condition is in an association, make sure -f was specified. #
# 7. Call RMC command rmrsrc using the condition name within a #
# selection string. Also pass along -VT if necessary. #
# 8. Return back any errors. #
