Problem with date script

[p0bman]

Hi,

I am trying to write a script in bash to find if a new domain has been added to our network.

I would like to be able to use an if stament to check the date on a log entry to see how long this has been happening.

e.g.

My out put looks like:

NEW Domain added at 11:36 on 20-10-05
WORKGROUP

NEW Domain added at 12:36 on 20-10-05
WORKGROUP

I want to be able to say the Workgroup WORKGROUP was added to the daomain on 20:10:05 at 11:36 and has been on for a total of 0 days 01:00

My script is as follows so far.

#!/bin/bash
HOME=/nt_domain
LOGS=$HOME/logs
DATA=$HOME/data
DOMAINLIST=$DATA/domain_list
DOMAINLOG=$LOGS/new_domain_list

DATE=`date +%H":"%M" on "%d"-"%m"-"%y`
smbtree --user=root[%password]|awk '{print $1 }'|grep -v 'knowndomain' > $DATA/domain_list

if [ -s $domainlist ]; then
echo "NEW Domain added at $DATE" >> $DOMAINLOG
cat $DOMAINLIST >> $DOMAINLOG
echo " " >> $DOMAINLOG
fi

If anyone can add any other enhancements that would be great.

date stuff in shell script is complicated - here are several very good scripts:

This isn't really an enchancement, just another variation.

#!/bin/bash
HOME=/nt_domain
LOGS=$HOME/logs
DATA=$HOME/data
DOMAINLIST=$DATA/domain_list
DOMAINLOG=$LOGS/new_domain_list
DATE=`date +%H":"%M" on "%d"-"%m"-"%y`

if [ -f $DOMAINLIST ]; then
echo "$DOMAINLIST already exists"
else
echo "Created blank $DOMAINLIST"
echo touch $DOMAINLIST
fi

# Create new read time for test condition
cat $DOMAINLIST > /dev/null
# Connect to domain tree and find any domain except 'knowndomain'
smbtree --user=root[%password]|awk '{print $1 }'|grep -v 'knowndomain' > $DOMAINLIST

# Test if $DOMAINLIST has changed since last read
if [ -N $DOMAINLIST ]; then
echo "NEW Domain added at $DATE" > $DOMAINLOG.`date +%Y%m%d`
cat $DOMAINLIST >> $DOMAINLOG.`date +%Y%m%d`
fi
