Calculate Row Percentage Bash One line Command -


i need know how calculate row percentages using 1 line bash command. suppose content of file test.tsv looks this:

item sort   clicks    clicks b item 1  100 50 item 2  60  40

i want know percentage each click sort item like:

item sort   clicks    clicks b item 1  66.70%  33.33% item 2  60% 40%

any ideas on how this?

use awk kind of thing, bash doesn't real/floating-point arithmetic.

awk script:

nr==1 { print } nr>1  { printf("%s %d %.2f%% %.2f%%\n"               , $1, $2               , ($3*100/($3+$4))               , ($4*100/($3+$4))               ) }

which means:

  • if line number 1, print as-is.
  • for other lines, print columns 1 , 2 as-is, calculate respective percentage columns 3 , 4.

in 1 line:

awk 'nr==1{print}nr>1{printf("%s %d %.2f%% %.2f%%\n", $1, $2, ($3*100/($3+$4)), ($4*100/($3+$4)))}' test.tsv
