Menampilkan Bilangan Prima Dengan Array (2-100)

$ ls -l | awk 'BEGIN {bil[100];}
END {for (i=2;i<=97;i++ ){
if(i%i==0 && i%2!=0 && i%3!=0 && i%4=0 && i%5!=0 && i%6!=0 && i%7!=0 && i%8!=0 &&
i%9!=0 || i==2 || i==3 || i==5 || i==7) {print bil[i],i;}}}'

Hasilnya adalah
2
3
5
7
11

Menampilkan Kriteria Nilai dan Nilai IPS

buat file contoh seperti dibawah ini dan beri nama filenya nilai

No Nama MalKul SKS Tugas UTS UAS
1. a RTOS 3 80 84 90
2. a AWK 6 70 95 80
3. a Matem 2 90 92 76
4. a bing 2 92 75 100

program menampilkan nilai IPS

awk' { nilairata=0; nilairata=($5+$6+$7)/3}
{{if(81<=nilairata && nilairata<=100){print $1,$2, $3,$4,$5,$6,$7,nilairata, "A", $8= 4*$2}}
{{if(71<=nilairata && nilairata<=80){print $1,$2, $3,$4,$5,$6,$7,nilairata, "B", $8= 3*$2}}
{{if(61<=nilairata && nilairata<=70){print $1,$2, $3,$4,$5,$6,$7,nilairata, "C", $8= 2*$2}}
{{if(51<=nilairata&& nilairata<=60){print $1,$2, $3,$4,$5,$6,$7,nilairata, "D", $8= 1*$2}}
{{if(0<=nilairata && nilairata<=50){print $1,$2, $3,$4,$5,$6,$7,nilairata, "E", $8= 0*$2}}
BEGIN {SKS=0}
{SKS=SKS+$4}
END { print "Total SKS= ", SKS}
BEGIN { Total=0 }
{Total=Total+$8}
END{print " Nilai total = ", Total}
BEGIN { IPS =0 }
{ IPS=Total/SKS}
END {print " IPS=", IPS}' nilai
