I occasionally run a bash command line like this:

n=0; while [[ $n -lt 10 ]]; do some_command; n=$((n+1)); done

To run some_command

    Yet another answer: Use parameter expansion on empty parameters:

    # calls curl 4 times 
    curl -s -w "\n" -X GET "http:{,,,}//www.google.com"
    

    Tested on Centos 7 and MacOS.
