Top Forums Shell Programming and Scripting Assigning array values using awk in shell scripting Post 302719999 by Corona688 on Tuesday 23rd of October 2012 11:31:46 AM

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! Smilie

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.

NAME
times - shell built-in function to report time usages of the current shell SYNOPSIS
sh times ksh times DESCRIPTION
sh Print the accumulated user and system times for processes run from the shell. ksh Print the accumulated user and system times for the shell and for processes run from the shell. On this man page, ksh(1) commands that are preceded by one or two * (asterisks) are treated specially in the following ways: 1. Variable assignment lists preceding the command remain in effect when the command completes. 2. I/O redirections are processed after variable assignments. 3. Errors cause a script that contains them to abort. 4. Words, following a command preceded by ** that are in the format of a variable assignment, are expanded with the same rules as a vari- able assignment. This means that tilde substitution is performed after the = sign and word splitting and file name generation are not performed. ATTRIBUTES
