How to receive a specific alphanumeric number from a sentence?
Hi,

I am quite new to shell scripting.
I am facing challenge in retrieving a specific number from a sentence from the log. the number is random and changes everytime in the log.
For example,

Code:
The number of rows updated in table is: 7000
The number of rows updated in table is: 8000
The number of rows updated in table is: 9000

Now i want to capture 7000,8000,9000 in a variable. How to do that?
