There's almost never a reason to dump a file into an array in shell, let alone a silly method that runs awk on the same line 7 times. I've seen people who think they have to run awk n times for n lines before, but n*7 times for n lines is a new one on me!  This accomplishes the output you wanted without awk or arrays in one line: Code:
$ tr -s ' \t' '\n' < /home/rama/expenese.txt 5032 210179 3110 132813874 53488966 11459221 5300794 $ If you really do want it stored in your shell, you could do this: Code:
# works in any bourne shell set -- `cat file` echo $1 echo $2 or Code:
# requires ksh set -A arrname `cat file` But again, there's almost never any reason to dump a file into an array in shell. Please explain your actual goal. Last edited by Corona688; 10-23-2012 at 11:38 AM.. |

What do you want to recall these values for? Why an array and not some other kind of variable? To recall them in order? That's what a shell for loop is for. |
