This creates an obvious complication because this script does NOT check for any other dependencies that the node
being deleted may have. You are responsible for making sure that any references and dependencies connected to the
deleted node are removed or corrected in the config.xml file.
The script treats all nodes the same. The syntax to run the script is
# ./delete-‐node {node name}.
To remove user 3:
# ./delete-‐node config.users.user3
The
delete-‐node
script
#!/bin/bash
#User must provide the node to be removed. e.g. "config.users.user1"
# Usage: delete-‐node {full node path}
if [ $# != 1 ]
then
echo "Wrong number of arguments"
echo "Usage: delnode {full '.' delimited node path}"
exit 2
fi
# test for spaces
TEMP=`echo "$1" | sed 's/.* .*/N/'`
if [ "$TEMP" = "N" ]
then
echo "Wrong input format"
echo "Usage: delnode {full '.' delimited node path}"
exit 2
fi
# testing if node exists
TEMP=`config -‐g config | grep "$1"`
if [ -‐z "$TEMP" ]
then
echo "Node $1 not found"
exit 0

# LASTFIELD is the last field in the node path e.g. "user1"
# ROOTNODE is the upper level of the node e.g. "config.users"
# NUMBER is the integer value extracted from LASTFIELD e.g. "1"
# TOTALNODE is the node name for the total e.g. "config.users.total"
# TOTAL is the value of the total number of items before deleting e.g. "3"
# NEWTOTAL is the modified total i.e. TOTAL-‐1
# CHECKTOTAL checks if TOTAL is the actual total items in .xml
