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.
