Regex pattern to show counters at zero "0"?

[Alex Willoughby]

Good afternoon,

im trying to get an regex pattern to show counters that are set to 0 on some catalyst switches.

so far ive tried

#sh interfaces counters | i _0^
#sh interfaces counters | i .0^
#sh interfaces counters | i $0^

but they all return nothing, from the below sample:

Gi1/0/29           17663            101             26              0
Gi1/0/30          807366           2667             42              7
Gi1/0/31               0              0              0              0
Gi1/0/32         3253549          12569             33              8
Gi1/0/33           17527            101             25              0
Gi1/0/34           17901            104             25              0
Gi1/0/35          192500           1231             10              0
Gi1/0/36           17663            101             26              0
Gi1/0/37           17119             93             26              0
Gi1/0/38               0              0              0              0
Gi1/0/39         3816293           8715             32              5

id hope to return g1/0/38 and g1/0/31

can someone help me out with this pattern?

Thanks

Depends on exactly what you need. 

So '#sh int counters | inc _0_' will show any line with a 0 in any of the columns if that is what you are looking for ?

that has narrowed it down a bit. is it possible to show interfaces were all columns are zero only?

You can just cut and paste a line from the output eg. 

#sh int counters | inc <paste one of the lines you want to see>

didn't think of that! the simplest solution is often right in front of you! Thanks Jon
