Looks like a field separator (FS) problem. The field separator is used by
'awk' to divide a line into fields. The default 'awk' field separator is
"\t" (tab) but your fields are separated by spaces. Try adding this inside
the BEGIN {} block:


FS = " ";


This would give you a script like this:


awk 'BEGIN { FS = " "; }
echo $2
END { print "Fin" }
' testclean

Alternatively, you may specify the field separator as an 'awk' option:

awk -F " " '<your script>' testclean

Oops! I zoomed in on the field separator issue without noticing that the
rest of your script isn't quite correct. Here's a one-liner that should
solve your stated problem:

awk -F "\t" '{print $2}' <filename>

This command will print the second tab-delimited field of every record of
a file.

I don't know that the FS should be declared in the BEGIN processing what
about

awk -F " " '{ print $2}' <file>
