[please do not toppost on usenet]

That depends on what you want to achieve.
I hope you try to experiment awith and learn something from this.

<script>
function test(x){
unix = x.unix.value
if(/^[a-z][a-z0-9]*$/i.test(unix)){
// (no whitespace, only alphanumeric, must start alpha)
return true // submit allowed
}
alert("Not an allowed string") // warning
return false // submit prevented
}
</script>

<form onsubmit="retur n test(this)">
<input name=unix>
<input type=submit>
</form>

IE6 tested
