#!/bin/bash
ls -l /usr/local/dir | grep username > /tmp/watchfile
while true; do
sleep 10
ls -l /usr/local/dir | grep username > /tmp/watchfile2
diff -q /tmp/watchfile /tmp/watchfile2 > /dev/null
if [ $? -ne 0 ] ; then
echo "New File was created"
exit ;
fi
cp /tmp/watchfile2 /tmp/watchfile
done
### Set initial time of file
LTIME=`stat -c %Z /path/to/directory/file.txt`
SIZE=$(du -B 1 /path/to/directory | cut -f 1 -d " ")
CHECK=$(du -sb /data/sflow_log | cut -f1)

while true
do
ATIME=`stat -c %Z /path/to/directory/file.txt`

if [[ "$ATIME" != "$LTIME" ]]
then
echo "RUN COMMNAD"
LTIME=$ATIME
fi
sleep 5
done
if [ -n "$(find . -user "$username" -print -prune -o -prune)" ]; then
echo "The current directory is owned by $username."

if [ -n "$(find . -user "$(id -u)" -print -prune -o -prune)" ]; then
echo "The current directory is owned by the current user."
