Top Forums Shell Programming and Scripting Split multiple blank, even if it's blank Post 302969048 by Scrutinizer on Thursday 17th of March 2016 10:20:50 AM

Try introducing tabs:
Code:
unexpand -t "18 30 66 88" file | awk -F'\t' '{print $1,$2,$3,$4,$5}'


---
With GNU awk 4 you can use field widths:
Code:
awk -v FIELDWIDTHS="17 12 36 22 20" '{print $1, $2, $3, $4, $5}' file

But then the fields contain spaces that need to be stripped//

Text::Tabs(3pm) 					 Perl Programmers Reference Guide					   Text::Tabs(3pm)

NAME
Text::Tabs -- expand and unexpand tabs per the unix expand(1) and unexpand(1) SYNOPSIS
use Text::Tabs; $tabstop = 4; # default = 8 @lines_without_tabs = expand(@lines_with_tabs); @lines_with_tabs = unexpand(@lines_without_tabs); DESCRIPTION
Text::Tabs does about what the unix utilities expand(1) and unexpand(1) do. Given a line with tabs in it, expand will replace the tabs with the appropriate number of spaces. Given a line with or without tabs in it, unexpand will add tabs when it can save bytes by doing so (just like "unexpand -a"). Invisible compression with plain ASCII! EXAMPLE
#!perl # unexpand -a use Text::Tabs; while (<>) { print unexpand $_; } Instead of the "expand" comand, use: perl -MText::Tabs -n -e 'print expand $_' Instead of the "unexpand -a" command, use: perl -MText::Tabs -n -e 'print unexpand $_' LICENSE
