Re^4: How do I use a template, csv file and script to generate multiple switch configurations

I can also add that my .csv now looks like this:

# ip,hostname,location
172.30.240.1,CUSOM-176-SWI-001,1st Fl N IDF
172.30.240.2,CUSOM-176-SWI-002,1st Fl N IDF
[download]

and my config template looks something like this:

hostname ##hostname##
interface Vlan1
 ip address ##ip## 255.255.255.0
snmp-server location ##location##
[download]

or at least, those are the lines from it that contain the variables.

A missing ; and a bit of re-ordering was all to be done. Now it should do the job but a lot of it is implicit and not obvious to the Perl starter. So be careful when expanding on it... #!/usr/bin/perl use strict; use warnings; use autodie; # usage: perl makeconfig.pl < host-ip.csv my $template_file_name="configtemplate.txt"; while(<>) { next if /^#/; chomp; my ($ip, $hostname, $location) = split (/,/); my $ofile_name=$hostname . ".txt"; open(TFILE, "< $template_file_name") \|\| die "config template f +ile $template_file_name: $!\n"; $ofile_name = $hostname . ".txt"; open(OFILE, "> $ofile_name") \|\| die "output config file $ofile +_name: $!\n"; while (<TFILE>) { s/##location##/$location/; s/##hostname##/$hostname/; s/##ip##/$ip/; printf OFILE $_; } close OFILE; close TFILE; } [download]	[reply] [d/l]
