I am trying to do a shell script to monitor if any files went through in the last hour.

There is a script in cron that runs every sec checking to see if a file is there and ftp the file out of this folder.

Now I just want to add a block of code that will check to see no files went in the last hour send an email.

ftp----------> folder to monitor ----------->ftp

This is what i came up with so far. I am getting a little problem calculating the time. If someone could help me out here please.



Code:

#Set the path to the folder to monitor
SUBJECT="DWH FILES WERE NOT SENT IN THE LAST HOUR"
FILE1="/home/tibco/javastuff/test/dwh*"


cd /home/tibco/javastuff/test/

###### Run list command
ls -l

time=`echo $line | awk '{ split($8,a,":"); print (a[1]*60)+a[2] }'`
FILEMATCH=`echo $line | awk '{ print $9 }'`


if [ $FILE1 = $FILEMATCH ]
  then
     echo "$time" > dwhtime.txt

     else
######## Run date command ##########
          date
          time2=`echo $line | awk '{ split($4,a,":"); print (a[1]*60)+a[2] }'`
       if [ $time2 -gt $time ]
           then
           mail -s "$SUBJECT" testemail <<EOF
          $SUBJECT
          $time
EOF
        fi

fi

Jonathan,
One way you can do this is:

for newFile in `find . -type f -newer special_named_file`
do
  echo "File = "$newFile
done
touch special_named_file

thats a good idea i will do that. Abou tthe time calcuations, do you have any idea how i should do this

In the code i am taking the time used in the ls -l command for that file and I am writing the time to a file, so when another file comes through it will overwrite the old time. So my issue is when no files comes for an hour I want it send an email

So would it be $time2 - $time1 = $b

if $b is greater than 60 mins then send email

How would i do this part?

You missed the whole point of Shell_Life's comment. The idea is to ask "find" for a list of files that are newer than 60 minutes. If that list is empty, you send mail. Touching the file after the loop finishes would work if your script is run every 60 minutes. If that is not the case, you could construct a timestamp 60 minutes in the past, and touch the file with the -t option at the start of the script. But to answer your question, the easiest way to check if a file is 60 minutes old or not would be to use perl. Here are a couple of perl one liners you can use in your script:

$ perl -e '@d=localtime ((stat(shift))[9]); printf "%4d%02d%02d%02d%02d%02d\n", $d[5]+1900,$d[4]+1,$d[3],$d[2],$d[1],$d[0]' file1.txt

$ perl -e '@d=localtime time()-3600; printf "%4d%02d%02d%02d%02d%02d\n", $d[5]+1900,$d[4]+1,$d[3],$d[2],$d[1],$d[0]'
