Top Forums Shell Programming and Scripting AWK separating a file into an array Post 302604045 by Corona688 on Friday 2nd of March 2012 04:10:26 PM

awk and shell variables aren't really related to each other. awk is its own language and has its own variables so, even when processed by awk, you're still faced with the same problem -- getting text output from a stream into variables in the arrangement you want.

An even simpler way is to just tell the shell to split on newlines, so you can cram the text in raw:
Code:
#!/bin/bash

OLDIFS="$IFS"
IFS=$'\n'

ARRAY=( `tail -n +2 file` )

IFS="$OLDIFS"

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
