Top Forums Shell Programming and Scripting Need help with sed and regexp Post 302691575 by Don Cragun on Saturday 25th of August 2012 01:11:02 AM

Note that if you're on a system that doesn't have gawk and awk's match() function only takes two arguments (such as on OS X), the following should also work:
Code:
awk -F = '$1 ~ /"(-*[0-9]+)"/ {
        split($1, f, "\"")
        sub( "\";", ";" f[2] "\";", p )
        next
}
        { if(p) print p
        p = $0
}
END { if(p) print p
}' input_file > output_file

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
