Bash script to get total size off of remainder calculated
I am working on a script to get the final total size and so far have the following and wondering if this can be improved.

# Compare the desired size of each lvm to the standard size. If it is desired is larger than calculate the difference and keep that value as the amount to add to that LVM.
# If the desired size is smaller than the standard than set the amount to add as 0.

Code:
If VarSize > VarStandard Then
VarAdd = VarSize - VarStandard
Else
VarAdd = 0
End If
 
If OptSize > OptStandard Then
OptAdd = OptSize - OptStandard
Else
OptAdd = 0
End If
 
If HomeSize > HomeStandard Then
HomeAdd = HomeSize - HomeStandard
Else
HomeAdd = 0
End If
 
If TmpSize > VarStandard Then
TmpAdd = TmpSize - TmpStandard
Else
TmpAdd = 0
End If
 
 
# Add up the additional amount required for each LVM to get the total additional required space
TotalAdd = VarAdd + OptAdd + HomeAdd + TmpAdd

My script flow for this:

Code:
#!/bin/bash
"$1"=5
"$2"=3
"$3"=2
"$4"=2

VarStandard=4
OptStandard=2
HomeStandard=1
TmpStandard=1

if (( $( echo "$1 > $VarStandard" |bc))); then
    VarAdd=$( $1 % $VarStandard ) 
      fi
  if (( $( echo "$1 > $OptStandard" |bc))); then
    OptAdd=$( $2 % $OptStandard ) 
  fi
  if (( $( echo "$3 > $HomeStandard" |bc))); then
    HomeAdd=$( $3 % $HomeStandard ) 
  fi
  if (( $( echo "$4 > $TmpStandard" |bc))); then
    TmpAdd=$( $4 % $TmpStandard ) 
  fi
  
if [ $(( VarAdd + OptAdd + HomeAdd + TmpAdd )) -eq 0 ] ; then
   echo "No Space needed"
  else
   echo "$(( VarAdd + OptAdd + HomeAdd + TmpAdd )) extra space is needed"
   fi
