[gentoo-user] OT: awk problem

[Dirk Heinrichs]

Hi,

maybe one of you can sched some light on this. I want to match a sequence of 
two digits with awk, but the following doesn't work

gawk '/([[:digit:]]){2}/' test_file

while it works as expected when using egrep, like

egrep ([[:digit:]]){2} test_file

Leaving out the interval also works, like in

gawk '/([[:digit:][:digit:]])/' test_file

but that would of course get worse when it comes to more than two digits. It 
also doesn't make a difference if I use [0-9] instead of [[:digit:]].

According to awk's man page its regular expressions are the same than those 
used by egrep. What do I miss?

Thanks...

	Dirk
