How to run a linux command in a loop?

Running a Linux command multiple times

Sometimes there is a need to run a Linux command multiple times without writing a shell script. For those times you can easily use the following snippet which is similar to how you would do in any programming language. It’s basically a For Loop which iterates through the command and number of times.

for ((n=0;n<10;n++)); do php deleteduplicates.php; done

in this case I have script name deleteduplicate.php which is a PHP script that I am running for 10 times.  you can just change the number to make it run more or less based on the input. I like this approach because it is readable and doesn’t need any addition program to be installed.
