bash – awk if then else snippet
A clear example of the if/then/else structure formatting in awk.
1 2 3 4 5 6 7 8 9 | $ awk ' BEGIN { FS="," ; FORMAT="%-10s%-8s%s\n" ; {printf FORMAT,"A","B","% age"} } { if($1>=$2) {printf FORMAT,$1,$2,100} else {printf FORMAT,$1,$2,($1/$2)*100} }' num.txt |
Output:
A B % age
34 140 24.2857
190 140 100
89 120 74.1667
110 110 100
