Thanks,

Thanks R.Singh. it works as expected.
one more question, I want to count total number of lines and put total number at end of the record. I don't know how to hold all the lines and print at end of each section. I tried below codes, no luck .
what I thought is to use array line[] to hold each line, at end, print the line and number. but it doesn't work like that.

please share you suggestion.

Code:
awk '/^\[/{val=$0;next} {if(!/^$/) {i++; print val,$0, i}}'

Code:
awk '/^\[/{val=$0;next} {if(!/^$/) i++; line[i]=$0}END{if(a in line) print val,line[i], i}'

Code:
awk '/^\[/{val=$0;next} {if(!/^$/) i++; line[i]=$0}END{if(a in line) print val,a, i}'

Code:
[abc_xxxx_yyyy] aaa 3
[abc_xxxx_yyyy] bbb 3
[abc_xxxx_yyyy] ccc 3
[abc_mmmm_nnnn] ddd 3
[abc_mmmm_nnnn] eee 3
[abc_mmmm_nnnn] fff 3
