Sorry
I am not sure what was wrong. 

I have a file which has two pattern

5673058-
AE-848/14271200-

in command line I typed:
awk '/^[0-9]/ { print }' file
, tried to get "5673058-" but it printed nothing
so I tried to type
awk --re-interval '/[0-9]{7}/ { print}' file
strangely, it didn't print "5673058-" but instead it printed "AE-848/14271200-"

my gawk version is 3.1.4

Thanks all

Mine is 3.1.3 and it works as expected:

$ printf "5673058-\nAE-848/14271200-\n" | awk '/^[0-9]/ { print }'
5673058-

$ printf "5673058-\nAE-848/14271200-\n" | awk --re-interval '/[0-9]{7}/ 
{ print }'
5673058-
AE-848/14271200-

$ awk --version
GNU Awk 3.1.3

So, at least you know it isn't your RE(s). If grep or sed don't find 
them, it's your file that's got control chars or something, otherwise 
it's your gawk version.

Regards,

Actually, I'm 99% certain it's not the gawk version, but the locale; the
original poster is in China.  It's probably better to use

	/^[[:digit:]]/

and

	/^[[:digit:]]{7}/

instead of [0-9].  I suspect that if the original poster uses

	export LC_ALL=C

before running gawk, things will work as expected.

It didn't work when I use /^[[:digit:]]/ without "export LC_ALL=C"

and both /^[0-9]/ and /^[[:digit:]]/ could work after "export LC_ALL=C" 

Thanks very much for all responses

Perhaps the file contains a CR character, so that it prints
"AE-848/14271200-" on top of "5673058-".
