awk print using a variable
hey, just want to ask how to do this. ex. Code:
g="hi i am john"
h=`echo $g | awk '{print $2}'`
echo $hOUTPUT is 'i' What if I want to use a variable instead of using '2', how do I do that? Because this one does not work: Code:
a=2
h=`echo $g | awk '{print ${$a}}'`this one also does not work: Code:
a=2
h=`echo $g | awk '{print $a}'`anyone? thanks! Last edited by Franklin52; 02-08-2012 at 05:19 AM.. Reason: Please use code tags for code and data samples, thank you |

In shell that supports arrays (bash/ksh): Code:
g="hi i am john"
i=2
h=( $g )
echo "${h[ $((i-1)) ]}" |
