Top Forums Shell Programming and Scripting How to transpose a table of data using awk Post 302219294 by s_becker on Monday 28th of July 2008 09:39:42 PM

Taken from the GNU AWK handbook:

{
if (max_nf < NF)
max_nf = NF
max_nr = NR
for (x = 1; x <= NF; x++)
vector[x, NR] = $x
}

END {
for (x = 1; x <= max_nf; x++) {
for (y = max_nr; y >= 1; --y)
printf("%s ", vector[x, y])
printf("\n")
}
}

Copy that to a file, then invoke it like this:

awk -f scriptfile datafile | awk '{ print $8"\t" $7"\t" $6"\t" $5"\t" $4"\t" $3"\t" $2"\t" $1"\t" }'

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
