Question Replace the content of file with incremented value
I have a file myfile with only one value 1000.I am using it in a shell script.Each time i run the script,the file shud get incremented by 1. I have used the below code for incrementing the value-
Code:
curr=`cat myfile`
echo $curr
curr=`expr $curr + 1`

But i am not sure how to save this replaced value back into the file.
Can anyone help me out?
