That's all.
or, try this.
$ awk '{for(i=2;i<=NF;i++)print $1, $i}' test.txt
I think awk is the best solution for this problem.
The following command does almost exactly what I want:
cat ./filename_introduced_user.txt | awk '{print $1" "$2; print $1"
"$3; print $1" "$4; print $1" "$5; print $1" "$6; print $1" "$7; print
$1" "$8; print $1" "$9; print $1" "$10; print $1" "$11; print $1"
"$12; print $1" "$13; print $1" "$14; print $1" "$15; print $1" "$16;
print $1" "$17; print $1" "$18; print $1" "$19; print $1" "$20; print
$1" "$21; print $1" "$22; print $1" "$23; print $1" "$24; print $1"
"$25; print $1" "$26; print $1" "$27}' | grep -v ' $' >
another_filename_introduced_user.txt
I am wondering whether it is possible to write a script to do the same
but for a number of columns introduced by the user.
Thanks in advance,
Paul
