Top Forums Shell Programming and Scripting Append text from one file to another based on a search from the end of a document Post 302465020 by marcozd on Thursday 21st of October 2010 01:09:40 PM

Hey - thanks very much - this worked but I had to change it slightly:

First, my system doesn't have nawk (i don't know why so I changed it to "awk" instead).

I also had to add a space in front of the "$HESS" because I didn't realize there actually was a space in the .dat file. Oops.Smilie

Thanks for your efforts but the scritp you suggested wasn't working - it didn't grab all of the text and the resulting output didn't have the "$END" in it.

Again, many thanks for your time and effort though.Smilie

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
