Shell Programming and Scripting

Hi,

I have scenerio where i need to check 3 files whether they are of current day files and then count should not be equal to zero.

how to achieve the same please let me know.

Vishal

Do have specific file names or file name patterns or could the three files have any name?

there are 3 different files and for one of the file i need to check count also if count is less then 0 i have to rerun the process

You're not making yourself very clear, is there a count (number) inside one of the files or do you you mean how many lines or bytes are stored in one of the files?

Let me explain you the full scenerio. For e.g i have 3 files created by informatica process and stored in Unix server and files are

1. a.txt
2 b.txt
3 c.txt

Now before i start my next process i need to make sure these files exists in folder and only b.txt has records in it i mean there should be some records inside the file or file should not be empty.

If the b.txt file is empty then i need to runmy informatica process again and make sure b.txt has data in it.

once b.txt has data then i go to next process.

overall i am checking two things here one is files are loaded today only today not yesterday and one of the file has data in it.

Okay, so you could do something like:

Code:

if [ -f a.txt -a c.txt -a ! -s a.txt -a -s b.txt -a ! -s c.txt ]; then
  # All three files exist, a.txt and c.txt are empty and b.txt is not empty
  echo ok
else
  # Rerun informatica process
  echo not ok
fi

Hi,

thanks for your reply, but i am confused could you please eleborate more.
