Somebody please please help me here
I am new to Unix and wanted to try on using command line arguments.

I am trying to write a program that would monitor a file and print something each time the file changes.

The problem is when I am exeuting the file with
a.out monitored_filename
it doesnt show me anything on the screen. I am not aware of how should I change the monitored_file so that it follows the loop and prints something. I tried to search it in the Unix book , but couldnt find anything.

if(fstat(filedes,&stbuf) == -1)
{
printf("couldnt stat \n");
exit(1);
}
for(;
{
if(stbuf.st_mtime != last_time)

printf("file modified");
last_time = stbuf.st_mtime;
sleep(60);
fstat(filedes,&stbuf);
}
}

Hi bubu,
may be this can help you out.

# org_file is your original file you want to monitored

cp org_file help_file

while true
do
LOG_DATE=`date '+%d.%m.%Y %H:%M:%S' `
X=`diff org_file help_file`
if [ -n "$X" ]
then
echo "File was changed at "$LOG_DATE
else
echo "File was not changed "
fi
cp org_file help_file
sleep 60
done
