You can use bc in bash to do maths calculations with decimals. The man pages can be found:
1 |
http://unixhelp.ed.ac.uk/CGI/man-cgi?bc+1 |
1 |
bc -l <<< "20 / ( 20 + 80) * 100 " |
1 |
20.00000000000000000000 |
1 |
-l = --mathlib = Defines the standard math library |
You can then use this with printf to limit the number of decimals shown: \\The example below shows the results to 3 decimal places. You can replace the 3 with what ever value you wish to place
1 |
printf "%.3f\n" $(bc -l <<< "20 / ( 20 + 80) * 100 ") |
1 |
bc -l <<< "($used / ( $free + $used) ) * 100 ") |
You are able to compare decimal numbers using bc. The output will return 1 or 0 depending on the results. You can then use this with an if statment -le / -ge etc
