Top Forums Shell Programming and Scripting How to replace multiple words together? Post 302953116 by Corona688 on Tuesday 25th of August 2015 11:41:02 AM

What does the text being replaced look like? If it's regular enough to do in a more intelligent way than a brute-force search that could help a lot. If not, perhaps not.

A brute force search in Perl won't be much faster than a brute force search in awk, the problem is the brute force search.

How big is new_word_list.txt ? Does the first column ever contain special characters? If you have GNU awk, it might be possible to build your own regex and play with a loop on match.

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
