This perl script reads-in a Template- and parameterdata-File and generates multiple Config-Files by replacing the placeholders
<parameterx> with the corresponding value on the parameter file.
The config files will be named after the first parameter in the data-file, so typically you should put the hostname as the first columns, then files will be named hostnamex.cli
Program arguments:
-h: just displays this help file
-t: template file with placeholder like <parameterx>
-p: parameter file with a comma or semicolon as separator, not a tab!
The first line must contain the names of the parameters
e.g. parameterx (this name is then used as placeholder)
Example:
perl genconfig.pl -p data.csv -t template.cli
The format of the data file (as an example) is as follows (separated by semicolons! Can be exported from excel!):
Hostname;Location;PrivateIP;PublicIP;PublicGW;MgmtIP;MgmtNatIP;ARLicense
Host1;anywhere;10.10.10.1;20.20.10.20;20.20.10.1;10.10.10.2;11.11.11.11;AR-1234567-1000000000-A1
Host2;there;10.10.20.1;20.20.20.20;20.20.20.1;10.10.20.2;11.11.11.12;AR-1234567-1000000000-A1
The first row carries the parameternames, these names are then used as placeholders (surrounded by brackets: <param1>) in the template file:

There are no limits on the number of parameters or length of files.
