My Problem is 'total_files' count always giving null in if block and i don't want to store in to a variable like
total_files=find . -type f -name '*.TXT' -print|wc -l
but when i checking manually cat total_files it is giving value 1
how to get values also in Total No of files :- cat`$total_files` Please advice me .
how can you check the count of file called total_files in if block?
and since you are storing the total file count in a file called total_files just cat total_files will display the count.
I am still unsure why you dont wanna use variable here? I cant see any pat of the code where it should be a file? If you want to be it as a file at the end of the code just echo the variable able store it in file.

Why don't you want to do:
This command sets the shell variable total_files to the number of files in and under the current directory whose names end in ".TXT". You can then find that value by expanding the variable using $total_files. The command you are using:
stores the same number in a file named total_files; not in a shell variable. When you store the data in a file, and don't set the shell variable, expanding the (unset) shell variable using $total_files will produce an empty string.
If you set the shell variable as shown above, then to put that number in your mail body, you could just use:
Rather than either of these, you'd probably be better off with a while read loop to actually remove the files and adjust the count based on the number of times you successfully removed a file.
Even more common (and much more efficient) would be to remove the files in the find command using a -exec rm {} +, but that wouldn't give you the number of files removed. (It would just tell you if all of the files more than five days old were successfully removed.)
