bash function to repeat a command

There may be a builtin to do this, but here is a function you can stick in your .bashrc. Usage: repeat N COMMAND COMMAND-ARGS. This will run COMMAND with COMMAND-ARGS, N times. Note that the quoting might be messy. I find this handy for running simple test scripts in a loop.

function repeat()
{
    count=$1
    shift
    if [ x$count = x ]
    then
        count=10
    fi

    n=0
    while [ $n != $count ]
    do
        eval $*
        n=`expr $n + 1`
    done
}
