Top Forums UNIX for Dummies Questions & Answers validate a pattern of numbers that are comma separated Post 302314036 by mgessner on Thursday 7th of May 2009 09:13:00 AM

You're not clear what this is for...
Are you talking about a command line utility? Or are you talking about a C program?

A simple awk script could do this if you're just validating an input file before doing something else.

I'm not the world's greatest authority on awk, as i tend to think of processing lines like I would in C, but this might help you.

#!/bin/awk

{ last=$1
for (i=2; i<NF; i++) {
if ($i < last)
exit NR
last=$i
}

This will return an exit code matching the first wrong line, or zero if everything is OK for all lines of the input.

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
