It looks to me like your script should work. What's the problem? — Barmar

You have some basic syntax errors.

When assigning variables, you can't have spaces around =. So it should be:

filename2=/home/user/chk.txt
text2=$file2

In the if, you're missing the [ command to perform a test, and the then and fi keywords.

if [ "$file2" = "username" ]
then
    sleep 60
fi

There's no pause command, it's sleep (you get it right later in the script).

But if you just want to check if a word is inside a file, you don't need a loop, you can use the grep command.

if grep -q username $file2
then
    sleep 60
fi
