Question relating regexp

[Robert.Land@t-online.de (Robert Land)]

This is a example one can find on one of the links
discribed in the deb HOWTO package:

=Section Multipliers(text just pasted):


"
An example from the phone list:
....
1248   Kate 634
....
1548  Kerry 534
....

To match a line that starts with a 1, 
has some digits, at least one space 
and a name that starts with a K we can write:

grep '^1[0-9]\{1,\} \{1,\}K' phonelist.txt
or use * and repeat [0-9] and space:
grep '^1[0-9][0-9]*  *K' phonelist.txt
"


=Why, in the first example, has the author
prefaced the char 'K' with the one or more
times multiplier? He only wants to find a 
name beginning with 'K'(!)

Then, in the snd grep command he doubled
'[0-9]', wouldn't only '^1[0-9]*....'be 
sufficent? Again, 'K' is prefaced with the
asterisk which doesn't seem necessary to me.




I hope one day all would agree on one standard.
