Question

I’m using grep to find verify some initial conditions at the beginning of a line, but I need the rest of the line after that to be alpha. I can’t figure out how to do it.

This is what I have so far:
^[0-9][0-9][0-9][[:alpha:]]+

This doesn’t work because if there is say a number or space one or more characters after it still returns it. I need it so just lines like 111saasniIUSABIBAFAib get returned.

Thanks

Use the $ token to match the end of the line like so:

^[0-9][0-9][0-9][[:alpha:]]+$
