min max and avg using awk is repeated many time..kindly use search option before posting thread.

Try :


Code:
$ cat <<eof | awk 'NR == 1{min = max = $2}{min = $2 < min ? $2 : min; max = $2 > max ? $2 : max; total += $2}END{print "Min :",min,"ms Avg :",total/NR,"ms Max :",max,"ms"}'
aaa: 3 ms 
aaa: 2 ms
aaa: 5 ms
aaa: 10 ms 
eof
Min : 2 ms Avg : 5 ms Max : 10 ms

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
