Thanks bakunin,

Actually files will be generated in time basis in the directory named "backup".
maximum file size is 10MB. if it reach 10MB it will write another file that i mentioned code below.

i want to write a program to check these files. whether these files are updating regularly or not. it should update regularly. if it is update regularly i need to print in echo " files are updating " ... if its not updating last 15 mins , i want to print in echo " files not updating"

Hope you understand my requirement.

Something like this,

#!/bin/sh

while true
do
var=`find /backup -name "SCP_*.log" -type f -mmin -15`
if [ -z $var ]
then
 echo "File Not Updating"
else
 echo "Success : File Updating"
fi
sleep 300
done
5 
#!/bin/bash
eval $(stat -s file)
[ $st_ctime -lt $(($(date "+%s") - 900)) ] && echo No update || echo Update

Dear pravin27..

Thanks.. but i'm getting some bugs. pls check the code and suggest me.

bugs:

find: bad option -mmin
find: [-H | -L] path-list predicate-list

Thanks in advance.

Try this,

#!/bin/sh

while true
do

TSTAMP=$(perl -e '($ss, $mm, $hh, $DD, $MM, $YY) = localtime(time() - 900);
printf "%04d%02d%02d%02d%02d", $YY + 1900, $MM + 1, $DD, $hh, $mm')

touch -t $TSTAMP file1
var=`find /backup -name "SCP_*.log" -type f -newer file1`
if [ -z $var ]
then
 echo "File Not Updating"
else
 echo "Success : File Updating"
fi
sleep 120
done
