Shell Programming and Scripting

Hi mens, it really helpful, I did it and Works OK!:
cat code.ksh

#! /usr/bin/ksh
awk '{
for(f=1; f<=NF; f++)
r2c[f","NR] = $f
} END {
for(f=1; f<=NF; f++) {
for(row=1; row<=NR; row++)
printf("%s\t", r2c[f","row])
print ""
}
}' $1

./code <file.txt> ... and voila!
Thanks shamrock

Lobaria: can you check whether NF and NR are defined in the END part? Just add a print statement. My hunch is that they will be zero in your version of awk.

Do you have nawk, or mawk, or gawk, or XPG4 awk on your system? Then try with one of those instead.

Modding the script so that it remembers the last values of NR and NF before the END section is not a complicated fix, as such.

Dear era, dear shamrock,

Thanks - Problem solved !
I was thinking along the same lines and installed gawk and it worked just fine.

Does anybody have an idea what the problem could be with my version of awk?

printf("%s\t", r2c[f","row])
print ""
}
}' $1

Well, my speculation would be that it doesn't remember the NF and NR values in END, since strictly speaking they are no longer defined in that context (intuitively speaking, at least).
