APAR status

• Closed as program error.

Error description

• The shell in RHEL 8.2 now outputs warnings such as:-
  
  ./nco_adduser: line 93: warning: command substitution: ignored
  null byte in input
  
  These are harmless but the nco_adduser and nco_removeuser
  scripts can be updated to prevent triggering the warnings.
  

Local fix

• Line 90 of nco_adduser can be modified from:-
  
  GROUPSTR=`$COMMON_ARCH_BIN_DIR/isql -S$OMNISERVER
  -U$OMNISERVER_USER -P$OMNISERVER_PASSWD -I$INTERFACES -b <<EOF
  
  to:-
  
  GROUPSTR=`$COMMON_ARCH_BIN_DIR/isql -S$OMNISERVER
  -U$OMNISERVER_USER -P$OMNISERVER_PASSWD -I$INTERFACES -b <<EOF |
  tr -d '\0'
  
  Likewise line 96 of nco_removeuser can be modified to be:-
  
  USERSTR=`$COMMON_ARCH_BIN_DIR/isql -S$OMNISERVER -Uroot
  -P$OSPASS -I$INTERFACES -b <<EOF | tr -d '\0'
