[ale] Read multiple variables

[Ed Cashin]

I bet you know already, but for completeness I guess it's worth mentioning
that awk can do it all, from the grep part to the while loop.

[ecashin at herlihy ~]$ awk -vuser=ecashin -F: '$1==user{print "U is " $1 ", G
is " $4 ", and it\x27s " $5}' /etc/passwd
U is ecashin, G is 1000, and it's Ed Cashin
[ecashin at herlihy ~]$
