1. You must have spaces on both side of opening and closing square brackets.

Code:
if [ $run -eq 10 ]; then


2. Make sure 'samp.csv' exists, Probably it exists in your current directory. Provide full path of all the files so that it can be read with-in cron.


3. What are you trying to achieve with 1=1000?

Exists where? IS it exist in the $HOME of the cron user?
As I said earlier please provide full path of the path (starts with "/").

You can't use absolute numbers as the variables name. Alphanumeric and underscore allowed but must not starts with number.

Code:
a1=1000 #allowed
1=1000 # not allowed
1a=1000 #not allowed
_a1=1000 #allowed

but the problem here is my
Code:
 a.log

file doe not increment the counter every time the cron is executing what might be the reason

Which shell are you using? Has the command executed successfully?
Try running the script manually and check whether the value of $run is being incremented correctly.

If you face any issues, Try replacing let run=($(cat a.log)+1) with run=$(( $(cat a.log)+1 ))
