I am trying to execute 3 command and get the output as a variable which needs some percentage calculation and display the same as the example. can this be executed as script.

First command output

$ isi status -q | grep -e "^Size" -e "^Used" -e "^Avail"
Size:573T
Used:448.0T
Avail:74T

Second command output

$ isi_classic snapshot usage | tail -n 1 | awk 'printf "tttSnapshot USED %=%.1f%%n", $4'
 Snapshot USED =0.6%
$ isi_classic snapshot usage | tail -n -1 | awk ' print "tttSnapshot USED:" $1'
 Snapshot USED=3.2T

example script awk script not working. after removed space

# isi status -q | grep -e "^Size" -e "^Used" -e "^Avail" | awk 'function print (num)
pipe pipe quote> /Size:/ TotalSize=$NF~
pipe pipe quote> /Used:/ TotalUsed=$NF
pipe pipe quote> /Avail:/ TotalAvail=$NF }
pipe pipe quote> END awk 'printf "Snapshot_per :%.1fn", $4'")
pipe pipe quote> Usedw/o=Total Used-Snapshot USED/Total Size
pipe pipe quote> print hostname ": " "t","Total Size:" Total_Size
pipe pipe quote> printf "tttTotalUsed:%.1fn", TotalUsed, "TB"
pipe pipe quote> printf "tttTotalAvail:%.1fn", TotalAvail, "TB"
pipe pipe quote> printf "tttTotalUsed %:%.1fn", used, "TB"
pipe pipe quote> printf "tttSnapshot Used :%.1fn", Snapshot_used, "TB"
pipe pipe quote> printf "tttSnapshot Used %:%.1fn", Snapshot_per, "TB"
pipe pipe quote> printf "tttUsed w/o:%.1fn", Usedw/o, TB)'
awk: syntax error at source line 1
 context is
 function >>> print <<< (num)
 missing

awk: bailing out at source line 7

Sample Requirement

Total Size : 573 TB
Total Used : 448.0 TB
Total Available : 74 TB
Total Used % : 86.1 % # Total Used(%) = Total Used/Total Size *100 = 86.1(%)
Snapshot Used : 3.2 TB
Snapshot Used % : 0.6 %
Used w/o : 85.5 % # (Total used)-(Snapshot used) / (Total size) = 85.49%

Original answer:

Totalanswer=$(command1 ; command2)
Subanswer1=$(echo $Totalanswer|grep Sub1)
Subanswer2=$(echo $Totalanswer|grep Sub2)
printf " Answer1:%sn Answer2:%sn" $Subanswer1 $SubAnswer2

Added comment:
The trick is in getting the required information by using the right tools. Using an external (ie. no native shell) command is to be avoided. Replacing the greps with bash native (hint) is left as an exercise for the reader.
