I tried this …
Code:
nawk '{a[$4]+=$3} END{for(k in a)print "["a[k]"]";}1'

but this gives me the TOTAL after reading all records ...like this

Code:
`0B0A RDF1+TDEV 45 BL_lmapm03
`0CE7 TDEV 59 BL_lmapm03
`0B09 RDF1+TDEV 70 BL_lmapm02
`0CE6 TDEV 59 BL_lmapm02
`0B08 RDF1+TDEV 70 BL_lmapm01
`0CE5 TDEV 59 BL_lmapm01
[129]
[129]
[104]

Try:
Code:
awk '/^`/{t+=$3}!/^`/{printf ("%23s[%d]\n","",t);t=0}1;END{printf ("%23s[%d]\n","",t)}' input
