config file, get field.

Hi Everyone,
I have a txt file: a.txt
Code:
a_b_ 3
c_d_e_ 55

(Assume this a.txt got 100 lines, here i just list 2 lines)
How should i get the 2nd field when 1st field eq c_d_e_. my way is:
Code:
`cat a.txt | grep c_d_e_ | cut -f2 -d' '`

Is there simple way, more efficient way in regular expression, perl? awk? and etc. Smilie
Thanks
