Thanks anbu23! I just have one question:
I tried with only one FILE_${m} containing 1.0 in each line on column 3.
So the average should be 7*1.0/7 = 1.0, but instead I get 0.142857 which is equal to 1/7.
So I replaced your solution with:
AVERAGE=$(awk ' NR==11 && NR<= 17{sum +=$3; if(NR == 17){exit}} END {print sum}' $FILE)
This time it works, but I don't understand why... any idea?
I have the following requirement.
file1.txt (this could contain 5 million rows)
ABC 1234 XYZ .... (3000 bytes)
QRD 4612 GHT .... (3000 bytes)
I need to create
file2.txt

I have a EAI process to change file2.txt into

Then I would have to use... (0 Replies)

Hi,
I am searching for an awk-script that computes the mean values for the $2 column, but addicted to the values in the $1 column. It also should delete the unnecessary lines after computing...

IGAWK(1) Utility Commands IGAWK(1)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
