awk redirect output to shell variable
I'm trying to redirect awk's output to a BASH variable. Currently the statement looks like this
options=`awk '{ while (i < NF) { print $i; ++i } }' answer but for some reason that makes $options look like this: 1 2 3 4 1 2 3 Now, the input file 'answer' is taken from a dialog checklist. So if I choose option 1, 2, 3, and 4, they are printed to $options twice, but in horizontal, then vertical order. And 4 is gone! Try to explain that. |
