This unix command is very powerful and with it we can calculate the mean, min and max of a data stored in file.

data.txt:

10
20
50
100
200
500

awk command:

awk ‘{if(min==”"){min=max=$1}; if($1>max) {max=$1}; if($1< min) {min=$1}; total+=$1; count+=1} END {print total/count, min, max}’ data.txt

Result:

146.667 10 500
