awk condiontals for grep like things and sum of the two - linux

Question

I have a Data in a file where I have some numbers with denomination like GB & TB and i have to sum them together .
Below is file data:
$ cat data_in_transit| awk '/TB/{print $6}'
1.26TB
1.24TB
2.85TB
1.03TB
1.07TB
1.01TB
$ cat data_in_transit| awk '/GB/{print $6}'
962.2GB
1005GB
892.5GB
910.0GB
823.4GB
1008GB
426.4GB
168.6GB
208.1GB
511.3GB
787.5GB
448.0GB
509.6GB
496.1GB
550.7GB
I can calculate them individually, however i want below two to be summ'ed into one query.
Anything starting with GB ..
$ awk '/GB/{sumGB+=$6}END{printf ("%.2f\n", sumGB / 1024)}' seoul_data_in_transit
9.48
Anything starting with TB ..
$ awk '/TB/{sumTB+=$6}END{printf ("%.2f\n", sumTB)}' seoul_data_in_transit
8.46
please suggest .

Answer 1

awk '$6~/GB/{s+=$6}$6~/TB/{s+=$6 * 1024}END{print s/1024,"TB"}' file

Answer 2

Assuming the current summation code generates the correct results:
awk '
/GB/ { sumGB+=$6 }
/TB/ { sumTB+=$6 }
END { printf ("%.2f GB\n", sumGB / 1024)
printf ("%.2f TB\n", sumTB)
}
' seoul_data_in_transit
Which should generate:
9.48 GB
8.46 TB

Answer 3

this is probably way overkill, but here's an unified way to sum up sizes for anything from Kibi-bytes to Yotta-bytes down to individual bytes without hard-coding them one-by-one :
mawk 'BEGIN {
OFS = "\r\t\t"
_ = "_KMGTPEZY"
gsub("[^_]","&B",_)
_+=_^=__=___=____*=_____=_
OFMT = \
CONVFMT = "%\047"((__=-_-+-++_^_)+_*_)".f"
__*=++_+!(_-=_=___=_*(_+_))
} $++NF=____+=int(___^index(_____, substr($!_,length($!_)-!_))*$!_)'
