Top Forums UNIX for Dummies Questions & Answers how to append spaces(say 10 spaces) at the end of each line based on the length of th Post 302280825 by quirkasaurus on Tuesday 27th of January 2009 03:47:09 PM

it sounds like you want a variable length record file turned into a fixed width record file.

Here's a general awk script you might be able to tweak:

awk '{ printf( "%-106.106s\n", $0 ); }' file_in > file_out

You can add search strings so it's more selective, if you need to.
But it won't hurt on records that are already the right length.

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
